I. Introduction
The purpose of this policy is to describe the communications systems of the Canton Police
Department utilized during routine and emergency activities.
The basic function of the communications system is to convey information. Dispatching
officers are the vital link between members of the public who request information or
services, employees who respond to calls for assistance, and other law enforcement and
public service agencies.
The speed and accuracy with which information flows through the Dispatch Center to the
person who needs it is a measure of the department’s capability to respond to the needs of
our employees and the community we serve.
II. Policy
It is the policy of this department to:
- Maintain an efficient flow of information essential to the functions of the department and
the community it serves; and
- Continually assess the effectiveness with which the department utilizes available
information technology in fulfillment of the department’s mission.
III. Procedure
The following procedures are intended to ensure that information of vital importance is
received and recorded properly. Although speed is of obvious importance regarding the
receipt of emergency information, reliability and accuracy are of primary importance.

7. Call Transfers 81.2.12
If it is necessary to transfer a call to another agency, obtain the caller’s name, phone
number, address and nature of the emergency prior to the transfer. Advise the caller
that they are being transferred, where they are being transferred to, and to remain on
the line.
8. Multiple Calls
Callers may be put on hold if necessary.
Determine the priority of each call.
Handle the call in order of priority.
Multiple calls may be received for a single incident. Advise additional
callers as such.
Ensure that multiple callers do not have a different emergency from the
one being handled.
9. Calls Placed on Hold
Callers should not be put on “hold” for any unreasonable length of time. If there is
going to be a delay:
Preface putting a caller on hold with a brief statement and explanation of
the reason why.
Get back to the original caller as soon as possible.
Under busy conditions, this process may be to be repeated.
Callers should not be put on “hold” for any longer than necessary.
Emergency calls should never be placed on hold.
10. Hang-up Calls
Hang-up calls must be considered to be emergency calls, and officers must be
dispatched to determine if assistance is needed. Using the caller-ID function in the
dispatch area, attempts will be made to determine the nature of the call. If the call
is determined to be an accidental 911 call, a unit will continue to that address
(without lights and siren) to confirm that it was in fact an accidental call.
11. Misdirected Emergency Calls 81.2.12
No caller shall be procedurally required to speak with more than two call takers.
When emergency 911 calls come in, the primary PSAP call taker is considered the
second person and the remote agency call taker is the first. It shall be this
Canton Police Department’s Central Dispatch Telephone & Radio Use Page 405PDF page 5Read textHide text
department’s policy to advise a calling party that the call is about to be transferred
and to remain on the line. The initial call will be handled promptly and routed
appropriately.
This department responds to emergency calls on a priority basis. This sometimes
includes responding to emergency calls where proper jurisdiction cannot
immediately be determined. A caller may report an accident, and not know the
exact location. First responding units will notify dispatch of what other agencies
and units are needed as quickly as is determined
12. Hearing Impaired Callers 81.2.1
The Dispatch Center provides 24-hour, toll free voice and TDD telephone access or
an equivalent system for emergency calls for service to the communications
impaired community who communicate by typing and reading their messages rather
than speaking and hearing them.
When a 911 call is received from a TTY Unit, the dispatching officer shall place the
call in TTY Mode and follow the instruction sheet on how to communicate.
A silent open call must be considered a potential TTY call unless proven otherwise.
If no voice response is given to a dispatching officer’s voice query, they shall
immediately send a TTY query to determine if a TTY caller is on the line.
If a call is received form a Telephone Relay Service, an operator will speak the
words typed by a TTY caller. The information will be given verbatim and the
operator will not deviate from the caller’s words. Responses from department
personnel will be typed by the relay service and forwarded to the caller.
13. Emergency Notifications 81.2.11
Delivering emergency notifications is a legitimate law enforcement function.
Requests for emergency notifications can come from a variety of different sources
such as citizens, hospitals, medical examiners, and other law enforcement agencies.
Our agency will accept and deliver messages that are “valid” and involve
emergency or exigent circumstances.
The following are guidelines on what types of messages are to be accepted and
delivered:
Well-being check on a resident. Dispatching Officer is to obtain enough
information to ensure that the request and circumstances are valid.
Request by another law enforcement agency to notify a resident to contact
them.
A physician’s office or medical facility requesting a well-being check be
done on a resident they feel may be in harm’s way.
14. Department Resources 81.2.5 A-G
The Dispatch Center will have the following information available at all times:
The name of the officer in charge; (d)
Canton Police Department’s Central Dispatch Telephone & Radio Use Page 506PDF page 6Read textHide text
Duty roster of all personnel; (b)
Telephone number of every agency member; (c)
Visual maps detailing the agency’s service area; (a)
A call screen showing the status of all on-duty officers/Officer status
indicators; (e)
Tactical dispatching plans; and (g)
Written procedures and telephone numbers for procuring emergency and
necessary external services to the agency (See Dispatch Manual) (f)
15. Telephone System
The Dispatch Center has two identical working stations. At each station, there is a
telephone with 10 incoming lines available. These phone lines can be used to make
outgoing calls as well. In addition to the landlines, there is one PSAP station at
each desk for 911 calls. Only employees who have been to NG911 Training are
authorized to answer any incoming PSAP calls.
In order to transfer an incoming call on the landline phone, the caller must be put on
hold. The call taker then hits Cnf/Trn button, the extension they are looking for and
then hangs up. Once he/she has hung up, the call transfer will be complete.
If there is no one in the Town’s Animal Shelter (after hours) or the Town Water
Department, then all their calls are automatically transferred to the Canton Police
Department’s number.
16. Failure of Telephone System 41.2.4
In the event of a failure of the telephone system anywhere in the station, dispatching
officers shall advise:
The shift Sergeant, using a radio or cell phone
A contact person from IT, using a cell phone
The Fire Department in the event that calls end up being directed to them
B) Radio Communications
An overview of the radio system is provided in General Dispatch Functions Policy
1. The radio system is the primary means of communicating with the Dispatch Center.
All department personnel engaged in field duties, including details, have
continuous two-way radio communications access to the Dispatch Center
and other officers by means of portable radios or vehicle radios. 81.2.2
All full-time sworn officers, reserve, permanent intermittent, special,
auxiliary, and animal control officers are issued portable radios.
2. Radio operations shall be conducted in compliance with the Federal
Communications Commission (FCC) rules and regulations. 81.1.2
All frequencies used by the department are properly licensed.
Canton Police Department’s Central Dispatch Telephone & Radio Use Page 607PDF page 7Read textHide text
An excerpt of the Code of Federal Regulations, Title 47, Part 90, which
govern our radio system type, is available on the internet at:
http://www.fcc.gov/encyclopedia/rules-regulations-title-47. 81.1.2
FCC rules prohibit: 81.1.2
Unnecessary transmissions
Transmissions not essential to law enforcement activities
False calls or fraudulent distress signals
The use of obscene, indecent or profane language.
3. Channel Usage
The main radio frequency is utilized for essential dispatching and coordination. It
is designated as “Canton PD 1”. “Canton PD 2” channel is to be used for officers
working:
High volume events;
Details where there is expected to be a lot of radio communication
between detail officers.
4. Call Designations 81.2.4 C
Personal names of employees will not be used during radio transmissions.
Dispatch Center employees are referred to as “Canton Control”.
Officers will be identified by either their cruiser number or “Officer (Their
last name)”.
For a large incident, the person in charge will be referred to as the Incident
Commander (IC).
Mobile Operations units will be referred to as “Charlie (followed by their
motorcycle number).
Mountain Bike units will be referred to as “Bravo Unit”.
5. Identifying Radio Users 81.2.4 C
Our radios send an ID code with every radio transmission. This shows on the Radio
Transmission screen at the end of every transmission, displaying a programmed
number – the portable ID number issued to those employees with radios.
Radio transmissions generated from a cruiser will reflect the cruiser number on the
Radio Transmission screen. If an officer is unable to speak, or the voice message is
too weak or garbled, the dispatching officer will be able to see the ID number
associated with who “keyed” their radio. 81.2.4 G
6. Dispatch Radio Features 81.2.4 G
All portable radios have an orange button located at the top of the radio.
This button can be pressed in emergency situations. This will cause an
audible and visual alarm on the Radio Transmission Screen. Other
officers will be able to hear the audible alarm both on their cruiser and
portable radios. Dispatching officers are trained to send assistance to an
Canton Police Department’s Central Dispatch Telephone & Radio Use Page 708PDF page 8Read textHide text
emergency request for assistance by dispatching all available officers
including officers on details and to silence and reset the alarm.
All portable radios have a purple button located on the side of the radio.
That is to be used when communicating “direct” with another officer on
portable radio. Each cruiser radio has a similar button.
Dispatching offices should have the main channel selected. In the event
that he/she needs to switch over to another channel, such as BAPERN, this
can be accomplished by clicking on that channel from the Radio
Transmission Screen.
The station garage doors can be raised or lower by clicking on the
designated “up” or “down” boxes located on the Radio Transmission
Screen.
There is a master volume control located on the Radio Transmission
Screen.
7. Required Communications 81.2.4 A, 81.2.4 E, 81.2.4 F
Offices dispatched to calls should maintain radio contact in order to clarify initial
information, if necessary, or to receive additional instructions. 81.2.4 A
Self-initiated calls such as motor vehicle stops and disabled motor vehicles, or when
the officer steps out of the cruiser for business purposes, shall be called into
dispatch and logged/recorded. 81.2.3 (2), 81.2.4 A
Upon arrival to a call, officers should access the situation and notify the dispatching
officer if additional assistance and resources are needed. 81.2.4 E
Dispatching officers should automatically start a back-up unit to the responding
officer’s location if the situation dictates it (i.e. To direct traffic around a motor
vehicle crash). No less than two officers will always be dispatched to a domestic
call. In some instances, more than one back-up officer is going to be needed;
usually to help with a search, establish a perimeter, or directing traffic.
Some examples include: 81.2.4 E
Scene of a multi-car accident
Fatality
Robbery
B&E in progress
Active fire or suspicious package call
