Phone Module Wiring

The 4285 or 4286 phone module is wired between the control panel and the

premises handset(s). It listens for touch tones on the phone line and reports

them to the control panel. During on-premises phone access, it powers the

premises phones; during off-premises phone access, it seizes the line from the

premises phones and any answering machines.

Note: The phone lines must be in service for the phone module to function,

even when accessing the system from an on-premises phone.

1. Make 12V (+) and (–) and data in and data out connections from the Phone

Module to the control, using the connector cable supplied with the Phone

Module (see Figure 16).

Color Lead Terminal On Control

GREEN DATA IN (terminal 6)

BLACK AUX – (terminal 4)

RED AUX + (terminal 5)

YELLOW DATA OUT (terminal 7)

2. Insert the keyed connector at the other end of the connector cable into the

mating header on the Phone Module (see diagram on next page for

location of the header).

3. Connect terminals 1 through 5 on either Phone Module as shown in the

Wiring Table below and in the 4285/4286 wiring diagram that follows.

Use an RJ31X jack with a direct-connect cord and make all connections exactly

as shown. If the leads on the direct-connect cord are too short to reach their

assigned terminals, splice additional wires to them, as required.

4285/4286 WIRING TABLE

4285/4286 Terminal Connects to:

1. Phone In (Tip) Terminal (21) on control.

2. Phone In (Ring) Terminal (22) on control.

3. Phone Out (Tip) BROWN lead from direct-connect cord.

4. Phone Out (Ring) GRAY lead from direct-connect cord.

5. Ground Earth ground terminal (25) on control.

6. Output High Not used (4285). Spkr Hi on 4286.

7. Output Rtn Not used (4285). Spkr Lo on 4286.

If no touch tones are produced following access to the security system from on-

premises (this problem may arise in rare cases), it may be necessary to

reverse the wires connected to terminals 3 and 4 on the Phone Module and the

wires connected to terminals (21) & (22) on the control. The wiring diagram

shows the wiring connections that will provide proper operation in most cases.

Caller ID Units

If the telephone system on the premises includes a Caller ID unit, connect the

unit directly to the “Handset” terminals (21 & 22) on the control, as

shown in 4285/4286 Phone Module Wiring Connections diagram that follows.
