RS-485 Bus Wire Run Limitations

The RS-485 bus from the first Panel Linking Module to

the last Panel Linking Module cannot exceed 4000 feet,

using 16-AWG twisted-pair cable.

The recommended form of wiring is to daisy chain the

connection from one unit to another. If several

buildings are to be connected, the RS-485 bus should

form a continuous path from one building to the next.

Avoid wiring units in a star configuration, where

multiple branches are formed. Star configurations

create loading and capacitance problems that are

complex, and become difficult to troubleshoot.

Mounting and Wiring the Panel Link Module

•

The PLM will not operate until the device is

enabled in the control’s

Device

Programming

#93 Menu Mode

•

Do not mount the PLM on the cabinet door

or attempt to attach it to the PC board.

To mount and wire the Panel Link Module, refer to

Figure 3-28

and

perform the following steps:

Step Action

1 Remove all power from the control panel

before making any wiring connections.

2 Mount the module in the control cabinet if

space is available or, adjacent to the cabinet,

using 2-faced adhesive tape.

3 Set the PLM’s DIP switches for a device

address between 01 and 30. See the module’s

instructions for the DIP switch table.

Do not use an address being used by another

device (keypads, RF receivers, etc.).

4 Connect the 12V (+) and (–) and data-out and

data-in connections from the PLM to the

control’s keypads terminals (6, 7, 8, and 9),

respectively.

5 Connect the 3-wire RS-485 cable between

each PLM. Recommended wiring is to bring

the wires “in” from one module (or control

panel) to terminals 5 (+), 6 (-), and 7 (G) and

“out” to the next module from terminals TB1-

8 (+), 9 (-), and 10 (G).

Long Range Radio Connected to the J7 Triggers

These triggers may be used to trip auxiliary alarm

signaling equipment such as ADEMCO’s 7720,

7720ULF, and 7920SE Long Range Radios.

The triggers are common to all partitions and must be

enabled for each partition (field 2

✳

20).

The fire and burglary/audible panic alarm triggers are

normally LOW and go HIGH until a

User Code + OFF

is entered in all enabled partition(s) that display these

conditions.

The silent panic/duress trigger latches HIGH, except

for duress, which is momentary.

Refer to the installation instructions that accompany

your radio for the connections to the control panel.
