Sandwich Dispatch

The new Sandwich Public Safety Communications Center
opened in June-July 2019 at the new Sandwich Police Station
at 255 Cotuit Road, Forestdale. The Comm Center has three
console positions, each having about 8 CAD screens
which include radio, mapping, log, and 911 screens.
The consoles can be elevated or lowered to dispatcher
preference to stand or sit.

Hyannis Fire Changes

February 20, 2018
The Hyannis Fire Department is currently building a new fire headquarters.
The new station will have a dispatch room in it, but

sometime around May 2018. Approximately 12 civilian dispatchers
were hired and are being training to do police dispatch and Hyannis
Fire Dispatch.

The transition follows other Cape Fire Departments
that have given up local in fire station dispatch for either a regional
dispatch center (Barnstable Sheriff's Office dispatches 10 fire depts)
or to town public safety dispatch centers (Sandwich & Falmouth)
that do both fire and police dispatch within the communities.

It is unclear whether any of the other fire departments within the
Town of Barnstable will continue as is or change to the Barnstable
Police option in the future. Currently Barnstable and West Barnstable
Fire Departments are dispatched by the Sheriff's Department,
while COMM and Cotuit Fire Departments are dispatched by COMM.

February 20, 2018

On February 19, 2018 the Hyannis Fire Department changed the way
they identify apparatus on the radio. For many years, all Cape FDs
have used the unique "county" radio designations on both the mutual
aid operations channels and on the local dispatch "fire alarm" channels.
Apparatus will continue to have "county" radio number assignments
for mutual aid purposes, but will use local IDs on fire alarm dispatch.

Car 1 = C801 = Fire Chief
Car 2 = C802 = Deputy
Car 3 = C803 = Duty Officer Car
Car 4 = C804 = EMS Officer
Car 5 = C805 = Fire Prevention Officer
Car 6 = C806 = Fire Prevention Officer
Car7 = C807 = Training Captain
Car 8 = C800 = Mechanic Vehicle
Engine 1 = FOX  = Antique Ahrens Fox
Engine 2 = E822 = E-One Pumper
Engine 3 = E823 = Pierce Pumper
Engine 5 - MACK = Antique Mack
Engine 6 = E826 = Pierce Pumper
Tower 1 = LT829 = Pierce Tower Ladder
Ambulance 1 = A831 = Ambulance
Ambulance 2 = A828 = Ambulance
Ambulance 3 = A825 = Ambulance
Ambulance 4 = A827 = Ambulance
R1 = H821 = Pierce Heavy Rescue
Marine 1 = Marine 808 = Fireboat
Marine 2 = Marine 809 = Small Boat
Dive 1 = Dive810 = Dive Truck
Service 1 = new Pickup
Service 2 = C830 = Service Van  



The transition of dispatching duties from the Hyannis Fire Station
to the new communications center at Barnstable Police took
place over a few days this week.  The new "Purvis" automated
voice dispatch went in service and use of the new CAD program
also went in service.

Hyannis Fire Alarm

The new communications center at the Barnstable Police Station
will soon (expected week of June 25, 2018) begin dispatching for
the Hyannis Fire Department. A dozen civilian dispatchers were
hired by the BPD and have been trained to dispatch the Hyannis
Fire Department as well as Barnstable Police.

The Comm center has 4 console positions, at least one of which
will be dedicated to Hyannis FD. Each dispatch station is setup
with about 7 computer displays including 911, CAD, mapping,
and touch screen radio controls.

As dispatching begins, so too will the use of a new CAD system
and a new "voice" on the radio.  The Computer Aided Dispatch
(CAD) system will use RedAlert to manage calls. As dispatchers
enter information into CAD, another program known as PURVIS
will quickly formulate and announce (dispatch) calls using a
computer generated, tone, voice and format. 

The new system is in use by a number of departments across the country, including Boston, but this will be a first on Cape Cod.

So when you begin to hear the new voice on the radio
you will know where it is coming from.

in the Hyannis Fire Station as long as anyone can remember.
That is about to change.


New Radios
The department recently issued all members new radios
which replace the old pagers carried by personnel for recalls.
The 8 channel radio receivers have a variety of settings allowing
personnel to be alerted by group or all call.  The Unication G5
radios are small and are able to monitor a variety of frequencies
including 400 mhz UHF and 800 mhz frequencies.

but will remain operational as their new headquarters is built over the next
18 months or so. This photo taken in the new comm room at the DPW Sept 2014.



Falmouth Dispatch

The new Falmouth Public Safety Communications Center
located in the Falmouth Police Station opened back in the
Spring of 2017.  The center has 4 dispatch stations in a quad
setup.  The Falmouth Police and Falmouth Fire dispatchers
are next to each other.  Two other positions allow for
backup or future growth.
Photos Oct 2017


Sandwich Dispatch

The Sandwich Police Department has been the 911 PSAP in town for years.
The police station right next door to the fire department would take calls and
transfer them next door for fire and EMS response. The center was staffed by
police officers, typically 1 per shift on a rotating assignment basis.

Early in 2016 that will be changing. Joint efforts between the fire and police
department are preparing the equipment, policies, procedures, and personnel
to open a combined communications center at the police station.

Currently the 4 civilian fire dispatchers work 24 hour shifts in the fire station
while police officers work the desk on 8 hour shifts. With the hiring of several
more civilian dispatchers, all fire, EMS, and police dispatching will be done
by 2 dispatchers sitting next to each other in communications center. All will
be cross trained to dispatch any type of incident, provide EMD, or greet the
public who come in to file complaints or have other business.

The communications center currently has 2 fully functional consoles
and one the move is made, a 3rd console will be brought over from the
fire station to allow for an extra position should it be needed at some time.

While older consoles were usually made up of steel panels and buttons,
today it is all done with a computer screen and a mouse / keyboard.
Dispatchers can see 911 data, mapping, a log, and status of various
resources directly in front of them and monitor various cameras located
around the station on another tv display.

March 2014






     The Hyannis Fire Department's dispatch officially transferred to civilian police-fire dispatchers at the Barnstable Police Station, 1200 Phinney's Lane on June 28, 2018.  Dispatch was previously done by on duty firefighters being rotated into dispatch duty at fire station.  The new dispatch program utilizes a digital generated voice dispatch of incidents called "Purvis."  Additionally, the department is now using a Computer Aided Dispatch program known as Red Alert with computers in apparatus. The department also recently issued all new receiving radios to replace older pagers for recall purposes.
July 2018

    The Hyannis Fire Department is planning to transfer its fire rescue dispatch over to the new Barnstable Police Department's civilian public safety dispatchers sometime in the spring of 2018. Hyannis is building a dispatch center in their new station, but it will be a backup to the primary option of the police department dispatch.
   Hyannis has also made significant changes to apparatus radio designations as of Fen 19, 2018
Car 1 = C801 = Fire Chief
Car 2 = C802 = Deputy
Car 3 = C803 = Duty Officer Car
Car 4 = C804 = EMS Officer
Car 5 = C805 = Fire Prevention
Car 6 = C806 = Fire Prevention
Car 7 = C807 = Training Capt
Car 8 = C800 = Mechanic
Engine 1 = FOX = Antique Ahrens Fox
Engine 2 = E822 = E-One Pumper
Engine 3 = E823 = Pierce Pumper
Engine 5 = MACK = Antique Mack
Engine 6 = E826 = Pierce Pumper
Tower 1 = LT829 = Pierce Ladder Tower
Rescue 1 = H821 - Pierce Heavy Rescue
Ambulance 1 = A831 = Ambulance
Ambulance 2 = A828 = Ambulance
Ambulance 3 = A825 = Ambulance
Ambulance 4 = A827 = Ambulance
Marine 1 = M808 = Fire boat
Marine 2 = M809 = small boat
Dive 1 = D810 = Dive truck
Service 1 = new Pickup Truck
Service 2 = C830 = Service van 



   The Sandwich Fire Department has implemented a rather significant change in their dispatching. As of Sept 22, 2017 a number of apparatus are being referred to by other than their "county" based radio numbers as has been the case since the late 1990's. 
    Essentially the Engines will now be referred to as Engine 1, 2, and 3 (corresponding to E451, E452, and E453). Tower 450 will now be called Tower 1. 
   The ambulances will be referred to as Ambulance 1, 2, 3 and 4. It appears that the Ambulance designation will be tied more to the station assignment (at the time) than the county number of the ambulances (A456, A457, A458 and A459). With the anticipated opening of the East Sandwich Station 2 in December 2017 (approximately) an ambulance would be assigned to each station and A4 would serve as a "reserve" unit.
    Other apparatus, such as the brush breakers and tankers will continue to be referred to by their county numbers (B461, T464, etc). 
    Some cars will be reassigned, Chief C-1 (441), Deputy C-2 (442), while others may continue to use their county numbers (C440, C467, etc).  The Duty Officer, when in C-460, will now utilize numbers assigned to officers with Captains by Seniority (C-3, C-4, C-5, and C-6) not corresponding to shifts, and numbers assigned to Lieutenants based on shift assignments (L-1, L-11, L-2, L-12, etc...) The EMS Officer will become C-8 and Fire Prevention will become C-9.  A system of "retiring" various portable numbers or officer numbers assigned to various personnel will also be used as retirements or promotions occur.  Confused??  The new listing will be posted on the Sandwich Roster page. 
Oct 2017    

The Joint Base Fire Department has added a STATION TONE in the dispatching of calls.  Their dispatch will pre-announce a call, follow it with the Station Tone and a specific Alert tone signifying either a medical response or a fire response.
Oct 2017

You may have noticed that COMM has changed some of their dispatching procedures, specifically reducing the number of times an "alert" tone is used on their talk-group for the initial dispatch of calls. Medical calls are typically not dispatched with the wobble (turkey) tone as has been done for many, many years. Primary alerting of personnel is still conducted on 154.355 which in primarily an in house paging and alerting channel.  Ambulances then sign on on the department's talk group and are acknowledged by dispatch. A straight alert tone is still mostly used for fire related incidents. This has been in place since early in the winter of 2017.
Updated Oct 2017

Falmouth Fire began being dispatched from the communications room at the Falmouth Police Station in the Winter of 2017.  Fire and police dispatchers are cross trained to do either position.

Sandwich Fire Dispatch is gradually transitioning next door into the Sandwich Police comm center. Equipment, policies, procedures, and personnel are being brought up to readiness for an expected transition early in 2016. Civilian dispatchers from the SFD and new hires will replace police officers who currently dispatch for the police. Changes will include dispatchers who currently work 24 hour shifts in the fire station going to 8 hour shifts on a 4 on, 2 off work week schedule. All will be cross trained to answer 911 calls, dispatch fire, EMS, or Police to various incidents in town.
Jan 1, 2016

Falmouth Fire Department and Falmouth Police Department may be combining dispatch centers. The town is trying to determine where the best site for a combined center would be.  The discussion has gone from the Gus Canty building (out of both police and fire stations), to using a larger space within the fire station, to using a smaller space within the police department. There are a number of concerns and costs involved with any of the choices.  More to follow.  Oct 2015

The Mass State Police Motorola Type II Trunking System that Cape Fire and Police Departments have utilized since the late 1990s was re-banded and activated in Feb 2013.

The re-banding program is a nationwide effort to reallocate radio frequency assignments due to improved technologies and increased demands for frequencies.

As a result, much of the radio communications devices, including personal scanners may need to be reprogrammed in order to work properly.

Scanning, which has been a popular hobby since the first scanners came out in the 1970s, has become significantly more complicated, but also in many ways improved as long as you have the right technology.

It is pretty much a given that you must have a Trunk Tracker type scanner to monitor local fire and police radios. It is also pretty important to utilize a computer and software to properly program the scanner correctly.

One of the alternatives to using a scanner is to utilize some of the online scanners that others may provide free or at a very reasonable price.

For those who have scanners locally, you may need the frequencies.


Updated Sept 2014



A little radio news for you all....

Those who monitor CMED and the EMS channels may have noticed some changes recently.

Massachusetts CMEDs have under gone a "narrow banding" of radio frequencies and all must utilize these new frequencies by January 1, 2013.

Essentially, narrow banding takes a radio spectrum or band of frequencies assigned to a certain purpose (ie CMED) and because of improvements in radio technology is able to squeeze additional frequencies into the same band width.

Rather than renumbering all the channels however, those common channels that have been narrow banded are simply called Med 2-N, Med 3-N, etc.
In-between each set of channels is a secondary 'new' frequency that has been added to the pool of possible channels. These are called 2-2, 3-2, etc.

So here on the Cape, where CMED previously used Med 2, Med 4, Med 5, Med 7, and Med 8 - the NEW set of channels that will be utilized are Med 2-N, Med 3-N, Med 4-N, Med 7-N and Med 8-2.





Scanner Listening



Cape Cod Area Scanning
     There are a number of important things to keep in mind when scanning public safety agencies in the Cape Cod area. First of all, to really listen to the fire and police activity you will need a TRUNK TRACKER RADIO. The Cape is on the Massachusetts State Police 800 mhz Motorola Type II Trunked Radio system. An ordinary scanner will not provide the control or scanning ability you need to hear the action.
    That being said, there are plenty of frequencies of interest in the area from 33mhz low band fire simulcast, to air and marine frequencies, to 400 mhz EMS radio, and much more.
    The Islands utilize 150 mhz high band and in Plymouth County it's mostly 400 mhz UHF.
    Listening to a good scanner (or two...) is a great way to keep track of what's going on.  This page will help you understand how best to listen, what the frequencies are, and more.
Listening Live
     One of the greatest things about the internet is the ability to Listen Live to scanner radio traffic that you would not be able to hear normally from where you live since scanners can only pick up within a certain distance. Online listening is a great way to enjoy your favorite departments.
    This page will help you listen in to the Cape Cod area. It will also introduce you to other areas such as Boston, Providence, Worcester, New York City, and more.
     We have several pages of frequencies that can be printed for your refrerence and scanner programming. There are also plenty of links to find frequencies for other areas you may visit.

Cape Cod Fire Departments have traditionally operated on the low band in the 33 mhz range. At one time all departments were on a single channel....33.70 mhz. As departments got busier and communications more frequent, many departments switched to their own "fire alarm" frequency. The 33.70 mhz channel continued to be used as a common "county" frequency for inter-department and mutual aid communications. By the late 1970's all departments were off the "county" frequency and operating on their own channels. The county frequency continued to be used, and is still in service today, for mutual aid purposes.

"Skip" used to be a very common problem on the 33. mhz frequencies, particularly the summer. To overcome this extremely irritating condition, all departments added PL (private line) tones (CTCSS) to radios. The common tone in the county is 114.8. This helped greatly in reducing the foreign noise.

As departments continued to grow in recent years, some added additional VHF and UHF frequencies that could be used for administrative purposes. Primary operations however, continued on the 33. mhz channels.

Today all Fire Departments utilize an 800 Mhz Trunked Radio System....See below.


Cape Cod Police Departments originally operated in the high band. The (4) channel 155. mhz police radio system was once utilized by all Cape Police Departments. Ch.1 operated by the Sheriff's Department was used for General Broadcasts (GBCs), General Info broadcasts (GIs), Be On the Look Outs (BOLOs) and other countywide communications. All departments used FCC callsigns. Each department had assigned car designations (Able, Baker, Charlie, David, Easy, etc...).

As communications increased, some departments aquired their own police channels, while others continued to use Ch.2, 3, and 4. Most of the departments continued to stay on 155. Mhz frequencies.

When 800 Mhz radios became available, some departments switched to 800 Mhz "conventional" frequencies with local repeaters. Others remained on VHF high band.

When the 800 Mhz Trunked Radio system came a couple years ago, all the departments still on the VHF high channels joined the 800 Trunked system. Departments which already had conventional 800 Mhz radio channels stayed on those.

Today, all Cape Police Departments are on 800 mhz, some trunked and some conventional.


Cape Cod Fire Departments have provided EMS service on the Cape for many years. In 1975 a 400 Mhz UHF EMS CMED radio system was installed providing ambulance to hospital communications for over 60 ambulances operating within the region. The Cape & Islands Emergency Medical Services System (CIEMSS) provided the system and the Barnstable County Sheriff's Department staffs and operates it.

Barnstable CMED is a system of radios, repeater sites, and telephone circuits which connect ambulances to (4) area hospitals. There are (6) repeater tower sites in the area, each having multiple channels available for "patches" to local hospitals. Channel 4 is the primary calling channel for rescue units. Channels 2,5,7 and 8 are available for "patching" an ambulance radio communication via phone line to the area hospital. It is a duplex system allowing two way conversations. Each channel has an input and output frequency. CMED is an active system with over 35,000 incidents per year being handled.


A few years ago, the Massachusetts State Police radio system upgrade to 800 mhz trunking began. Cape Fire and Police Departments worked out arrangements to join with the State Police Trunking System. The result has been a considerable change in Cape Cod communications. While not yet 100% completed, the system has been utilized quite reliably now for over (2) years.

The "Trunked Radio System" is someone complex to understand and explain, but basically it is a Motorola Type II system. It presently utilizes a bank of (15) 800 mhz frequencies. Within these frequencies is a "data" channel which allows user radios to track communications by user groups known as "Talk Groups." The system utilizes several repeater sites on the Cape. All radios must reach the repeater site to transmit. A very sophisticated computer controls the whole system. These frequencies are shared by all Cape Cod Fire Departments, most Police Departments, the State Police, Environmental Police, and perhaps more.

Mobile and portable radios issued to fire departments have (3) banks of 16 channels each.

The "A" Bank, contains the home department's channel, a mutual aid dispatch channel, 5 neighboring departments, the local police channel, a Capewide Administrative channel, a CIEMSS talkgroup, and (5) common I-Call / T-Tac channels. Channel 1 in the "A" bank is a low power, Direct channel. Radios in the "A" Bank typically can scan the home channel, neighboring departments, and the mutual aid dispatch channel.

The "B" Bank in each radio contains the remaining fire department channels not included in the "A" bank.

The "C" Bank has the home channel, (3) OPS channels for major incidents, and other channels.

The "C" Bank in each radio was designed for use at multi-department incidents. Channel 1 is the Direct channel. The direct channel is a conventional 800 (not trunked). This is paired with the C2 channel which is the home department's primary channel. C1 and C2 scan each other. If for some reason, a portable in a building cannot transmit out (it is unable to hit one of the cape's repeater sites), the person in the building can switch to the direct C1 position to reach command or other units on the scene. The (3) OPS channels are similarly paired....C3 is direct/C4 is OPS 1..........C5 is direct/C6 is OPS 2......etc.... Each pair scans itself for this "backup" for emergency purposes. The direct channel frequency is the same in all positions.

The Cape does not utilize a "regional" or centralized dispatch center. Each of the Cape's Fire Departments have their own dispatch centers, each department uses its own channel (Talkgroup), and all of the departments using the "Trunked" system simulcast radio communications over their 33. mhz frequencies for tone activated pagers. Most dispatch centers have (1) A fire alarm channel for dispatch and day to day operations...simulcast over 33. mhz, (2) a countywide "Mutual Aid Dispatch" channel used for inter-department and mutual aid dispatch purposes. This is strictly used for station to station communications and is not used for mobile or portable communications. Dispatch centers then use mobile radios which can be selected as needed for access to OPS channels during major incident.

Protocol for an incident is basically as follows. Each department dispatches its incidents on their own "fire alarm" talkgroup (A2 and C2 positions on their radios.) These communications, including pager tones, are simulcast on their 33. mhz frequency. When a working fire or major incident is encountered, the fire alarm dispatcher contacts the mutual aid center via phone or the M/A Dispatch talkgroup, and is assigned an "OPS channel" for fireground / incident communications. All units responding to and operating at the incident are instructed to switch to an OPS channel (OPS 1, 2, or 3). Units on scene will stay on the OPS channel until the incident is concluded. Units given coverage / moveup assignments are dispatched by the mutual aid center on the M/A Dispatch talkgroup. As apparatus responds, it remains on its own fire alarm channel until reaching the community to be covered. Upon reaching that community, apparatus switches to the fire alarm talkgroup of the department being covered and remains on that channel for assignments. If additional moveups occur, units switch to the talkgroup of the next community being covered. It is complex and may be confusing to follow... but so far it works.

Monitoring fire communications on the Cape by scanner has actually improved greatly with the 800 trunked system. Obviously, having a newer scanner with "Trunk Tracking" capability helps to provide best control over what you hear. Listening with older, non-trunking radios has also improved, as the process of simulcasting communications has made it possible to hear portable radios as well as mobiles in most cases. Monitoring with a Trunk Tracker scanner involves programming the (15) 800 mhz frequencies and then the 5 digit talkgroups of the departments you wish to hear.

The trunked system is being improved on again at this time with additional repeater sites being installed soon to provide the desired 95%/95% coverage for in building use.

Presently all Cape Fire Departments are capable of using the 800 mhz trunked system. Mobile and portable radios, as well as dispatch center radios are in place. Due to some concerns about "in building" coverage, Hyannis and Yarmouth Fire Departments have not yet made the switch to 100% use. The West Barnstable Department has shared a low band frequency with the Barnstable Fire Department. This creates a situation with simulcasting, so WBFD has not switched to 800 mhz yet pending a new 33. mhz channel to put pagers on. All other departments are on and working well.

The Mutual Aid Center for Barnstable County (Barnstable County Control) is located at the barnstable Sheriff's Department in Barnstable. This is the center piece of Cape Fire Communications.
