3.5 Telephone Connections

Use the following steps to make the telephone

connections to the control panel:

1. To prevent jamming of signals, wire the RJ31X jack

or RJ38X jack to support line seizure as shown in

Figure 5.

2. Install the jack on the street side of the phone

switch, wired ahead of any PBX equipment. Line

seizure temporarily interrupts normal phone usage

while the control panel transmits data.

3. Confirm that the control panel seizes the line,

acquires dial tone, reports correctly to the receiver,

and releases the phone line to the in-house phone

system.

4. Connect the telephone cord’s flying leads to the

telephone terminals as shown in Figure 6 (Red to A;

Gray to A1; Brown to B1; Green to B).

5. Plug the other end of the cord to the RJ31X jack or

RJ38X jack.

3.6 Keypad Wiring

Consult your keypad’s installation manual for complete

installation instructions. Connect the keypads to the

keypad bus or option bus terminals as shown in Figure

Keypads contain static-sensitive

components. Follow anti-static procedures

when handling the keypads.

Shared cable is not recommended for

keypad, multiplex, options bus, telephone,

or siren wiring.

Connections

1- Keypad bus—You can use up to 15 keypads.

Can be “home run” or “daisy-chained.”

Maximum wire length for each is 305 m

(1000 ft). Maximum total wire length in system

is 1830 m (6000 ft) when using 0.8 mm (#22

AWG) or 1.0 mm (#18 AWG) cable.

2- Phone line

3- Keypad. Keypads 1 to 10 connect to the

keypad bus, and Keypads 11 to 15 connect to

the option bus. See Section 3.9 Option Bus

Wiring.

3.7 Zones 1 to 8 Wiring

Zones 1 to 8 are intended for connection of Normally

Open or Normally Closed alarm contacts. They can

also be used for compatible 2-wire smoke detectors.

These zones require a 2.21 kΩ resistor (P/N 25899) at

the end of the loop. Power is momentarily removed

from L+ after a [PIN][System Reset] or during a fire

verification. See Figure 7 terminals 19 through 30, and

see Figure 8.

Zones 1 to 8 assignments are programmed in Address

0031 to 0038. See Section 5.9.2 Zone Programming:

Assigning a Zone Function to the Zone.
