panel. Connect all yellow wires from the keypads to the

“YEL” terminal on the panel. Connect all red wires from

the keypads to the “RED” terminal. Connect all black

wires from the keypads to the “BLK” terminal.

Power-up Procedure

If the keypads are located a distance from the panel,

install an extra keypad temporarily at the panel during

power up testing. An extra keypad with a short length of

cable and alligator clips attached is helpful for testing and

programming PC2550 systems.

Connect the transformer, wait approx. 5 seconds.

Enter a few keypad commands and open a zone to be

sure that the panel and keypad are responding to signals.

If the keypad does not respond and there are no

indicators on, check for AC voltage at the “AC” terminals.

If there is 16 VAC present, check that the keypad wiring

is correct and check the keypad/auxiliary supply fuse. If

the keypad/auxiliary supply fuse is blown check for a

short between the keypad red and black wires before

replacing the fuse.

If the keypad is responding normally, connect the battery.

The red battery lead attaches to the positive battery post

and the black battery lead attaches to the negative

battery post.

Note : THE PC2550 WILL NOT START UP IF ‘AC’ IS OFF

AND THE BATTERY IS LOW.

Testing The System

See Installer’s test - [✱] [6] [Master Code] [0] (page 9), or

do the following. Contact the monitoring station to request

a transmission test. Plug the telephone cord into the

RJ31-X jack. If a DTS-1 is being used to monitor

communicator transmissions, connect as described in

“Bench Testing” section and place the DTS-1 in the line

mode by pressing the red “LINE/LOCAL” button. Arm the

panel, wait for the exit delay to expire and trip a detector

on an instant circuit. Wait for the communication to

complete. Disarm panel and check with the monitoring

station to confirm the transmission. Perform additional

transmissions required by the monitoring station.

Check the “Trouble” light on the keypad. If it is on, press

[✱] then [2] to determine if there is a system trouble. The

“Trouble Display” section in “Keypad Commands” gives a

description of the different trouble conditions.

Instructing End-User

Fill out the system reference guide in the PC2550

Instruction Manual. Check off sections in the manual

which apply to the user’s system and make additional

notes if necessary.

Describe the system to an authorized user. Describe

arming and disarming procedures. Describe the basic

keypad functions. Assist the user in working through

examples of each type of command.

Provide user(s) with the Instruction Manual and instruct

them to read the manual to become familiar with the

system operation.

Instruct the user to test the system on a regular basis as

described in the Instruction Manual. The Master Code

should be changed from the default setting and recorded

in the Instruction Manual.

the [#] key. To determine the nature of the trouble, press

[✱][2]. (See the “Trouble Display” section.)

Zone Input Terminals “Z1” to “Z8”

Zone inputs “Z1” to “Z8” are supervised end of line

(E.O.L.) resistor circuits. Each input must be terminated

with a 1K ohm E.O.L. resistor. An alarm condition will be

created if a normally open contact is used to short across

the E.O.L. resistor. An alarm is also created if normally

closed contacts, wired in series with the E.O.L. resistor,

are opened. See the wiring diagram for normally open

and normally closed contact connection. The type of

circuit or zone definition (delay, instant, 24 hour etc.) is

programmed from the keypad using the [✱][8] Installer’s

Programming commands ("Programming Guide" section

[14]).

Note: For UL installation, zone inputs must be

terminated with normally closed initiating devices or

end of line resistors.

Telephone Terminals “TIP”, “RNG”, “T-1” and “R-1”

The wires from the RJ31-X telephone jack are connected

to these terminals in the following way.

TIP Green wire

Incoming line from

RNG Red wire

telephone company

T-1 Brown wire

Outgoing line to

R-1 Grey wire

house telephone(s)

Note: Ensure that plugs and jacks meet the dimension,

tolerance and metallic plating requirements of 47

C.F.R. Part 68, Subpart F.

For proper operation there must be no other telephone

equipment connected between the control panel and

the telephone company's facilities.

Do not connect the alarm panel communicator to

telephone lines intended for use with facsimile (FAX)

machines. These lines may incorporate a voice filter

which disconnects the line if other than FAX signals

are detected, resulting in incomplete transmissions.

Battery Connections

Do not connect the battery or the transformer until the

wiring is complete. Connect the red battery lead to the

positive battery terminal and the black lead to the

negative battery terminal. If the connection is made in the

reverse the battery fuse will fail. The battery charging

voltage is factory adjusted for 13.8 volts and normally

needs no adjustment. If the battery charging voltage is

out of adjustment contact your service representative.

Note: The battery charging voltage must not be

adjusted on UL listed systems.

Keypad Installation

Mount the keypads near the exit-entry doors. The

PC2550RK keypad has a red, a black, a green and a

yellow wire on the back. Connect these four wires to the

four keypad terminals on the control panel using four

conductor (quad) telephone wire. Up to three keypads

may be connected to one PC2550. Connect all green

wires from the keypads to the “GRN” terminal on the

1 2 3 4 5 6 7 8 9 10 ... 43 44
