WARNING Please Read Carefully
Note to Installers
This warning contains vital information. As the only individual in
contact with system users, it is your responsibility to bring each
item in this warning to the attention of the users of this system.
System Failures
This system has been carefully designed to be as effective as
possible. There are circumstances, however, involving fire, bur-
glary, or other types of emergencies where it may not provide
protection. Any alarm system of any type may be compromised
deliberately or may fail to operate as expected for a variety of
reasons. Some but not all of these reasons may be:
■ Inadequate Installation
A security system must be installed properly in order to provide
adequate protection. Every installation should be evaluated by a
security professional to ensure that all access points and areas
are covered. Locks and latches on windows and doors must be
secure and operate as intended. Windows, doors, walls, ceilings
and other building materials must be of sufficient strength and
construction to provide the level of protection expected. A
reevaluation must be done during and after any construction
activity. An evaluation by the fire and/or police department is
highly recommended if this service is available.
■Criminal Knowledge
This system contains security features which were known to be
effective at the time of manufacture. It is possible for persons
with criminal intent to develop techniques which reduce the
effectiveness of these features. It is important that a security
system be reviewed periodically to ensure that its features
remain effective and that it be updated or replaced if it is found
that it does not provide the protection expected.
■Access by Intruders
Intruders may enter through an unprotected access point, cir-
cumvent a sensing device, evade detection by moving through
an area of insufficient coverage, disconnect a warning device,
or interfere with or prevent the proper operation of the system.
■Power Failure
Control units, intrusion detectors, smoke detectors and many
other security devices require an adequate power supply for
proper operation. If a device operates from batteries, it is possi-
ble for the batteries to fail. Even if the batteries have not failed,
they must be charged, in good condition and installed correctly.
If a device operates only by AC power, any interruption, how-
ever brief, will render that device inoperative while it does not
have power. Power interruptions of any length are often accom-
panied by voltage fluctuations which may damage electronic
equipment such as a security system. After a power interruption
has occurred, immediately conduct a complete system test to
ensure that the system operates as intended.
■Failure of Replaceable Batteries
This system’s wireless transmitters have been designed to pro-
vide several years of battery life under normal conditions. The
expected battery life is a function of the device environment,
usage and type. Ambient conditions such as high humidity,
high or low temperatures, or large temperature fluctuations may
reduce the expected battery life. While each transmitting device
has a low battery monitor which identifies when the batteries
need to be replaced, this monitor may fail to operate as
expected. Regular testing and maintenance will keep the system
in good operating condition.
■Compromise of Radio Frequency (Wire-
less) Devices
Signals may not reach the receiver under all circumstances
which could include metal objects placed on or near the radio
path or deliberate jamming or other inadvertent radio signal
interference.
■System Users
A user may not be able to operate a panic or emergency switch
possibly due to permanent or temporary physical disability,
inability to reach the device in time, or unfamiliarity with the
correct operation. It is important that all system users be trained
in the correct operation of the alarm system and that they know
how to respond when the system indicates an alarm.
■Smoke Detectors
Smoke detectors that are a part of this system may not properly
alert occupants of a fire for a number of reasons, some of which
follow. The smoke detectors may have been improperly
installed or positioned. Smoke may not be able to reach the
smoke detectors, such as when the fire is in a chimney, walls or
roofs, or on the other side of closed doors. Smoke detectors
may not detect smoke from fires on another level of the resi-
dence or building.
Every fire is different in the amount of smoke produced and the
rate of burning. Smoke detectors cannot sense all types of fires
equally well. Smoke detectors may not provide timely warning
of fires caused by carelessness or safety hazards such as smok-
ing in bed, violent explosions, escaping gas, improper storage
of flammable materials, overloaded electrical circuits, children
playing with matches or arson.
Even if the smoke detector operates as intended, there may be
circumstances when there is insufficient warning to allow all
occupants to escape in time to avoid injury or death.
■Motion Detectors
Motion detectors can only detect motion within the designated
areas as shown in their respective installation instructions. They
cannot discriminate between intruders and intended occupants.
Motion detectors do not provide volumetric area protection.
They have multiple beams of detection and motion can only be
detected in unobstructed areas covered by these beams. They
cannot detect motion which occurs behind walls, ceilings, floor,
closed doors, glass partitions, glass doors or windows. Any type
of tampering whether intentional or unintentional such as
masking, painting, or spraying of any material on the lenses,
mirrors, windows or any other part of the detection system will
impair its proper operation.
Passive infrared motion detectors operate by sensing changes in
temperature. However their effectiveness can be reduced when
the ambient temperature rises near or above body temperature
or if there are intentional or unintentional sources of heat in or
near the detection area. Some of these heat sources could be
heaters, radiators, stoves, barbeques, fireplaces, sunlight, steam
vents, lighting and so on.
■Warning Devices
Warning devices such as sirens, bells, horns, or strobes may not
warn people or waken someone sleeping if there is an interven-
ing wall or door. If warning devices are located on a different
level of the residence or premise, then it is less likely that the
occupants will be alerted or awakened. Audible warning
devices may be interfered with by other noise sources such as
stereos, radios, televisions, air conditioners or other appliances,
or passing traffic. Audible warning devices, however loud, may
not be heard by a hearing-impaired person.
■Telephone Lines
If telephone lines are used to transmit alarms, they may be out
of service or busy for certain periods of time. Also an intruder
may cut the telephone line or defeat its operation by more
sophisticated means which may be difficult to detect.
■Insufficient Time
There may be circumstances when the system will operate as
intended, yet the occupants will not be protected from the emer-
gency due to their inability to respond to the warnings in a
timely manner. If the system is monitored, the response may
not occur in time to protect the occupants or their belongings.
■Component Failure
Although every effort has been made to make this system as
reliable as possible, the system may fail to function as intended
due to the failure of a component.
■Inadequate Testing
Most problems that would prevent an alarm system from operat-
ing as intended can be found by regular testing and maintenance.
The complete system should be tested weekly and immediately
after a break-in, an attempted break-in, a fire, a storm, an earth-
quake, an accident, or any kind of construction activity inside or
outside the premises. The testing should include all sensing
devices, keypads, consoles, alarm indicating devices and any
other operational devices that are part of the system.
■Security and Insurance
Regardless of its capabilities, an alarm system is not a substi-
tute for property or life insurance. An alarm system also is not
a substitute for property owners, renters, or other occupants to
act prudently to prevent or minimize the harmful effects of an
emergency situation.

Section 2: Getting
Started
2.1 Installation Steps
The PC4936 module must be installed by SERVICE PERSONNEL ONLY. It
must be installed in a metallic cabinet properly grounded. It is the installer’s
responsibility to ensure such degree of protection for the equipment that
NO ACCESS to the TNV circuit is given to the end user. The metallic cabinet
must be secured to the building structure before operation. A proper ground
connection must be provided for the metal cabinet. Internal wiring must be
routed in a manner that prevents:
• excessive strain on wire and on terminal connections
• loosening of terminal connections
• damage of conductor insulation
Follow these steps to install the PC4936 Audio Interface module and audio
stations. Review this section to get an overall understanding of the order of
installation. Once this is done, carefully work through each step.
Step 1 Mounting the PC4936 Audio Interface Module
Mount the cabinet close to the control panel as the PC4936 must be con-
nected to the incoming telephone line. Before attaching the cabinet to the
wall make sure to press the nylon circuit board mounting studs into the cab-
inet from the back.
Step 2 Connecting the PC4937 Module (optional)
To add 8 ports to the system, connect the PC4937 to the PC4936 module. See
the PC4937 Installation Sheet for instructions.
Step 3 Wiring the Combus
Wire the Combus to the PC4936 Audio Interface module according to the
diagram provided in 2.2 “Combus Wiring” on page 4.
Step 4 Wiring the Audio Stations
Wire each audio station according to the diagram provided in 2.3 “Audio
Station Wiring” on page 5.
Step 5 Wiring the Incoming Telephone Line
Wire the incoming telephone line according to the diagram provided in 2.4
“Telephone Line Connection” on page 6.
Step 6 Enrolling the PC4936
You must enroll the PC4936 on the system before it will work. To enroll the
PC4936, enter programming section [0200] then scroll to PC4936. To enroll

system keypad. Refer to Section 4: “Programming” on page 11 for informa-
tion on each programming section.
Helpful Installation Tips
Feedback
If an intercom station appears to be exhibiting feedback noise, check the fol-
lowing for potential causes.
• Microphone - Remove the backplate. The microphone and holder are located
in the bottom-left corner. Ensure that the microphone is pushed fully into the
black rubber holder so that the face of it is flat against the rubber.
• Speaker - Ensure that the felt is secured around the speaker.
• Gain Control - Remove the backplate. The speaker volume control is
located directly above the microphone and the microphone sensitivity
control is located directly beneath the speaker. Turning either of these con-
trols counter-clockwise will reduce their gain, thereby reducing the possi-
ble level of feedback.
• Placement - Avoid installing intercom stations directly across from one
another. Feedback may also occur due to room acoustics which will be
affected by several different factors such as the size of the room, whether
or not the floor is carpeted and the objects in the room. Try moving one of
the intercom stations to correct the problem.
• Ventilation - In some extreme instances the station may be feeding back to
itself. The speaker output may be feeding back into the microphone
within the housing. To eliminate this, open a hole through the wall equal
in size to the rectangular opening in the backplate to allow the sound to
escape.
2.2 Combus Wiring
The PC4936 Audio Interface module has 4 terminals marked Combus (red,
black, yellow and green). Connect the four Combus terminals on the PC4936
to the four terminals on the control panel marked Combus (red, black, yel-
low and green).
firealarmresources.com

5
2.3 Audio Station Wiring
Up to 7 audio stations can be connected to the PC4936 Audio Interface mod-
ule. Each station must be home-run to the interface module via a shielded 22
gauge, 4 wire cable. Each PC5921 can be up to 1000’/303m from the PC4936;
each PC5904 can be up to 500’/151.5m from the PC4936.
Connect each station to power (red - AUX, black - COM) and to the proper
audio connections on the PC4936 module (yellow - speaker, green - micro-
phone). Connect the drain wire of the shield to the COM terminal on the
PC4936 module or the black terminal of the station (make sure the drain
wire of the shield does not short anything on the back of the board), but not
both. Refer to the diagram below:
Avoiding Audio Station Interference Noise
The Combus wiring and several different electrical devices (fluorescent
lighting, etc.) may induce noise onto the intercom wires. For this reason
shielded wire should be used whenever possible. If shielded wire is not
used, each intercom wire must be spaced a minimum of 4 ft./1.2 m from all
Combus wiring, electrical wiring, fluorescent lighting and other sources of
electrical interference. If this is not possible, shielded wire must be used
with the drain of the shield connected as indicated in the above diagram.

2.4 Telephone Line Connection
The PC4936 has 4 terminals for the telephone line connection (TIP, RING, T1
and R1). The wiring must be as follows:
• Incoming line - PC4020 TIP and RING
• PC4020 T1 and R1 - PC4936 TIP and RING
• PC4936 T1 and R1 - house telephone
NOTE: If there is an Escort4580 on the system, connect the modules to
the telephone line as shown below.
2.5 Music Input Wiring
The music input must be wired to a single port, using an audio signal which
does not exceed 200mV peak to peak. To do this, connect the music source to
the microphone input for a port:
• connect one side of the source to the microphone input - one of terminals
M1 to M7, or M8 to M15 (if a PC4937 is used).
• connect the other side to a COM terminal.
Program the port to which the music source is connected for Music Input.
See section 4.1 “Port Definitions” on page 11.

Section 3: Audio
Functions
3.1 Paging
Users can page people on the premises using the intercom stations.
NOTE: Only one page can be performed at a time.
To initiate a page press the Page/Answer button on any station. The station
beeps twice. If no beeps are heard it is because another conversation is
already taking place. If the page is successful all other stations that are not
on “Do Not Disturb” will sound a rapid beep. Talk into the audio station.
The system broadcasts your voice to all other interior audio stations.
To answer the page, press the Page/Answer button on another station. The
station beeps twice to indicate that a connection is established between the
intercom stations where the page was initiated and answered. No other sta-
tion will transmit the conversation.
The PC4936 automatically detects the source of the loudest voice and uses
this to control the direction of conversation. During a page, the Do Not Dis-
turb (DND) light will be on when the microphone of the intercom station is
active.
To end a page, either person can press the Page/Answer button. If the
PC4936 detects silence for 30 seconds, it will end the page.
3.2 Page Listens To All
You can program the system so that when a page is initiated, users at all
other intercom stations can respond hands-free for 30 seconds (i.e., without
pressing the Page/Answer button). Ports in DND mode, or which have the
Paging/Monitoring/Doorbell Sounds option turned off will not be able to
answer the page.
A user who wants to talk for longer than 30 seconds can press the Page/
Answer button to establish a private communication link. If the page is not
answered within 30 seconds, it will time out.
3.3 Cancelling a Page
To cancel a page, press the Page/Answer button a second time. The page
will automatically be cancelled if there is no response in 30 seconds.
3.4 Do Not Disturb
To avoid receiving pages, doorbox calls or incoming telephone calls, users
can put a station on Do Not Disturb (DND). To do this, press the Do Not
Disturb button on the station. The Do Not Disturb light on the station will
come on to indicate the unit is in Do Not Disturb mode.
To take a station off DND, press the Do Not Disturb button again. The Do
Not Disturb light on the station will go out.

3.5 Answering Doorbells
Exterior stations (PC5921EXT, PC5921EXT/R) can be programmed as door-
box 1 or doorbox 2 for doorbell operation. When someone presses the but-
ton on a doorbox 1 station, it will broadcast a “dingdong” sound over the
system. Doorbox 2 will broadcast a “dong” sound over the system.
To answer the doorbell users can press the Page/Answer button on any sta-
tion. The audio channel will operate the same as it does for a page.
If a page is in progress when a doorbell is pressed the two persons on the
page will hear the tone. To answer the doorbell either person can press the
Page/Answer button. The page will end and the user will immediately be
connected to the doorbell station.
3.6 Opening the Door
You can program any intercom station to open the door (using a doorstrike
module) while in communication with a doorbox station. After answering a
doorbell on an intercom station, press and hold the Page/Answer button for
2 seconds to activate the doorstrike. The system will sound an acknowledg-
ment beep. The PC4020 will trigger the programmed Command Output (1 -
8), which will activate the PGM output connected to the doorstrike. See sec-
tion 4.3 “Doorstrike Function Button” on page 11.
To terminate communications with the doorbox station, press the Page/
Answer button briefly.
3.7 Door Chime
If the door chime feature is enabled for zones on the system, when a zone is
violated or restored, the keypads on the partition will beep. If an Escort4580
v1.3 is connected to the system, it will announce the label for the zone which
generated the door chime over the audio stations.
3.8 Monitoring
The Monitor feature allows users to listen-in on one area at any other inter-
com station (except stations on DND). To listen-in on an area, go to the sta-
tion in the area and press and hold the Do Not Disturb button for two
seconds. The station will be put in Do Not Disturb mode and the Do Not
Disturb light will flash. The PC4936 will transmit all sounds heard from that
station to all the other stations on the system.
Other features such as paging, door answer and answering incoming calls can
still be performed and will override the monitor feature. If a page, door
answer or telephone call answer is in progress the monitor feature will not
operate until the conversation is ended. To turn off the monitor feature press
the Do Not Disturb button once. The red light on the station will stop flashing.
Only one station at a time can be monitored. To monitor another area, turn
the monitor feature off on the first station.
3.9 Answering Incoming Calls
When an incoming call is detected, the PC4936 will sound a ringing tone on
all stations which are enabled to sound the tone (unless on Do Not Disturb).
To answer the call the user must press the Page/Answer button for 1 sec-

ond. Once the call is answered the audio channel will operate the same as it
does for a page.
The call will end if the user presses and holds the Page/Answer button for 1
second. The call will also end after 30 seconds of silence.
If a page is in progress when an incoming call is detected only the two users
on the page will hear the ring. To answer the call either user can press and
hold the Page/Answer button for 1 second. The page will end and the user
will immediately be connected to the incoming call.
If a user has answered a telephone call at an intercom station and then the
doorbell is pressed, the user will hear the doorbell. The user can press Page/
Answer to hang up the telephone, and then press Page/Answer one more
time to answer the doorbell.
3.10 Transferring and Holding Calls
Once a user has answered a call on an intercom station, they can:
• put the call on hold
• transfer the call to an in-house telephone
• page someone so that the they can answer the call at another intercom station
To put a call on hold press the Do Not Disturb button once. Once the call is
on hold, you can page someone else to answer the call, or answer door-
bells as usual.
To pick up a holding call at a telephone, go to the telephone, pick up the
receiver and press the [#] key for 1 second. This puts the call through to the
telephone and disconnects the intercom station from the conversation.
To pick up a holding call at any intercom station, press the Do Not Disturb
button.
3.11 Call Waiting
If you have answered the telephone through an audio station and a second
call comes in, the station will ring. To answer the second call while on line
with the first call, press the Page/Answer button. This puts the first call on
hold and answers the second call. To return to the first call press the Page/

To turn on the background music, enter user programming [*][6][Master
Code], then press [9]. To turn off the music, enter [*][6][Master Code][9] again.
NOTE: The monitor and music input feature cannot be on at the same
time. If both are turned on monitoring will take priority and the music
will not be heard.
3.14 Alarm Follower
The audio stations will sound alarm conditions along with the bell output of
the control panel. All stations will sound an alarm using Burglary and Fire
type tones. All Burglary alarms will sound a steady alarm output. All Fire
alarms will sound a pulsed alarm output.
3.15 Verbal Alarm Announcements
If you have installed an Escort4580 v1.3 on the system, when zones go into
alarm the Escort will announce the labels for those zones over the intercom
system. The alarm announcement will be as follows:
• an alarm tone
• verbal announcement of the first zone in alarm
• verbal announcement of the latest zone in alarm
• series repeats until alarms are silenced.
See section 4.6 “Verbal Alarm Options” on page 12 for more information.
3.16 Central Station Talk/Listen-in
When a Talk/Listen-in event occurs the PC4936 will seize the telephone line,
call the central station and initiate a talk/listen-in session. The PC4936 will
start a session of low-gain listen-in on the station closest to the zone in
alarm, or on all stations if the CS Listen All option is on (see 4.9 “Central
Station Talk/Listen-In” on page 13). When the central station operator
presses any key on the telephone a new session will begin.
If a Holdup, Panic or Duress alarm occurs, the operator will only be able to
listen-in, as the speakers will not be turned on. See 4.9 “Central Station
Talk/Listen-In” on page 13 for information on programming which events
will trigger a Talk/Listen-in session.
Central station operators can control the Talk/Listen-in session using the
keys on their Touch-Tone* telephone. You can program the functions of
these keys by following the instructions in 4.10 “Central Station Talk/Lis-
ten-In Commands” on page 14.
NOTE: Doorbells and monitoring will not work when Talk/Listen-in
mode is on.
NOTE: If Talk/Listen-in is active and another event occurs, the PC4936
will end the Talk/Listen-in session and transmit the event to the central
station. For UL Listed applications, the maximum on-line time must be
limited to 30 seconds.

Section 4: Programming
Refer to the PC4020 Installation Manual for programming instructions. The
following section explains all the programmable features including how the
feature operates and options for the feature.
4.1 Port Definitions
Ref #: [001600XX00], where XX = ports 01-15
Each PC4936 has 7 ports that can be connected to audio stations. Program
ports 08 - 15 only if you have installed and enrolled an PC4937 (8-port
expansion module).
One port can be connected to a music input. Program that port as [04].
Only PC5921EXT and PC5921EXTR exterior boxes should be defined as [01]
Doorbox 1 or [02] Doorbox 2.
Program all PC5921 Interior Audio and PC5904 Central Station Talk/Listen
stations as [03] Intercom.
Program all unused stations as [00].
• Option [00] - Not Used • Option [03] - Intercom
• Option [01] - Doorbox 1 • Option [04] - Music Input
• Option [02] - Doorbox 2
4.2 Audio Station Options
Ref #: [001600XX01], where XX = port 01-15
You can disable certain features of each interior audio station using the fol-
lowing toggle options. All options are turned on for each station by default.
• Pag/Mon/Drbell: When you turn this option off, pages, doorbell sounds
and monitoring will not be broadcast to the station.
• Incoming Rings: When you turn this option off, incoming telephone calls
will not ring at the station.
• Doorstrike: When you turn this option off, users will not be able to unlock
the door (using the doorstrike) from the station.
4.3 Doorstrike Function Button
Ref #: [001600XX02], where XX = port 01-15
If you set up the doorstrike function button, when users answer a doorbell
page, they will be able to open the door near the doorbox station. See section
3.6 “Opening the Door” on page 8.
For this feature to work, you must:
1. Connect the doorstrike module near the doorbox to a PGM output terminal.
2. Program the PGM output for one of Command Outputs 1 - 8. (See your
PC4020 Installation Manual for information on PGM output programming.)
3. Program each internal audio station to trigger the Command Output.
(Ref #: [001600XX02], where XX = port 01-15)

4.4 Page Listens To All
Ref #: [001601]
Enable the Page Listn All option to allow all stations which hear pages to
respond without having to press the Page/Answer button. If the page is
answered, normal page activity will take place. If the page is not answered,
it will time out after 30 seconds. See also 3.2 “Page Listens To All” on page 7.
4.5 Handsfree Doorbell Answer
Ref #: [001601]
Enable the Handsfree Dr. option to allow all stations which hear doorbell
pages to respond without pressing Page/Answer. As well, visitors initiating
the doorbell page will be heard on all other stations which hear pages. If the
doorbell page is not answered, it will time out after 30 seconds.
4.6 Verbal Alarm Options
If you have installed an Escort4580 v1.3 on the system, when zones go into
alarm the Escort will announce the labels for those zones over the intercom
system. The alarm announcement will be as follows:
• an alarm tone
• verbal announcement of the first zone in alarm
• verbal announcement of the latest zone in alarm
• series repeats until alarms are silenced.
You can program two options on the PC4936 to customize the verbal alarm:
Alarm Tone Time
Ref #: [001602]
Program the length of time the alarm tone will sound before the zone label is
announced. Default is 015, valid entries are 000-255 seconds. If programmed
for 000, no alarm tone will sound.
Bells Active During Verbal Alarm
Ref #: [001601]
If the Bel. Verbal Alm toggle option is on, the system bells will sound
throughout the verbal alarm announcement. If this option is off, the system
bells will sound during the alarm tone, but will pause while the Escort
announces the label(s) of the zone(s) in alarm.
4.7 Zone Port Assignment
Ref #: [001606]
When the Central Station Talk/Listen-In feature operates, the panel will
automatically turn on the station closest to the alarm. For this to operate
properly you must program the Zone Port Assignment to tell the panel
which zone is closest to each station. When the communication link is estab-
lished the central station operator will hear input from the station closest to
the alarm.
NOTE: Program the Zone Port Assignments even if zone alarms are not
used. Tampers, Openings and Closings, and all other events will not
function if ports are not assigned to zones.

4.8 Keypad Port Assignment
Ref #: [001607]
Use this section to tell the panel which keypad is closest to each audio sta-
tion. This is important for the User Help, Verbal Alarm and Verbal Door
Chime features to work correctly. See section 3.12 “User Help (Keypad func-
tion key)” on page 9 and section 4.6 “Verbal Alarm Options” on page 12.
4.9 Central Station Talk/Listen-In
Ref #: [001601]
NOTE: Enable the “Event Buffer Follows Swinger Shutdown” option in
the control panel if Central Station Talk/Listen-In is used.
You can program the PC4936 to initiate a Talk/Listen-in session with the
central station for any or all of the following events (for UL Listed applica-
tions the maximum on-line time should be 30 seconds):
• Zone alarms
• Miscellaneous alarms (Police Code, Door Forced Open and Open Too
Long alarms)
•Tampers
• Openings
• Closings
• Auxiliary alarms
• Panic alarms
• Duress alarms
• Opening after alarm
If the Openings and Closings options are enabled, you should also enable
the Duress Alarm option.
NOTE: In all cases, a reporting code for the event must be programmed
in the control panel. For example, if a reporting code for a zone alarm is
not programmed, an alarm in the zone will not initiate a Talk/Listen-In
session.
NOTE: Module tampers will not initiate a Talk/Listen-in session.
For Talk/Listen-in to work correctly on zone alarms, you must assign each
zone to the closest audio station (see 4.7 “Zone Port Assignment” on page 12).
NOTE: Zones programmed as silent will not initiate a Talk/Listen-in ses-
sion. Only a Listen-In session will occur.
To have the PC4936 turn on Talk/Listen-in on all stations (instead of only
the one closest to the alarm), enable the CS Listen All option.
The Talk/Listen-In communication will end after the programmed Listen-in
Time expires (ref #: [001603]). The central station operator can extend the on-
line time by pressing any key on their Touch-Tone telephone or entering the
extend time command (see 3.16 “Central Station Talk/Listen-in” on page 10
and section 4.10 “Central Station Talk/Listen-In Commands”, below).

4.10 Central Station Talk/Listen-In Commands
Ref #: [001604XX], where XX = key number 00-11
Ref #: [001605XX], where XX = mode key number 00-11
When the panel transmits a reporting code to central station and Talk/Lis-
ten-In is initiated, the panel will pass the telephone line to the PC4936 for
Talk/Listen-In. The PC4936 will then turn on the closest station to the alarm,
or, if the CS Listen All option is enabled, all stations will turn on.
Once the central station has established the Talk/Listen-in link the operators
can control the session by pressing keys [0] through [9], [#] and [*] on their
Touch-Tone telephone. Additional commands can be programmed as Mode
Keys, which are two button entries on the Touch-Tone telephone.
The central station may be using other Talk/Listen-In equipment. You can
program the PC4936 so that central station operators can use the same com-
mands for all equipment. Ask your central station how they need the com-
mand keys to be programmed.
The following commands are available:
00 Key not used 09 Terminate session
01 Talk to all speakers 10 For future use
02 For future use 11 Cancel keypress
03 High gain listen to all 12 For future use
04 For future use 13 Zone select
05 For future use 14 Increase microphone input
06 Low gain listen to all 15 Decrease microphone input
07 Extend time 16 For future use
08 For future use 17 Mode key
