Installing the RF Receiver

Installation Guidelines
•
The receiver can detect signals from transmitters within a nominal range of 200 feet. Take this
into consideration when mounting the receiver.
•
Mount the receiver in a high, centrally located area for best reception. Do not place the receiver on
or near metal objects or inside a metal cabinet.
•
For maximum range, the receiver should be at least 10 feet from the control panel or any remote
keypads to avoid interference from their microprocessors.
•
If two RF receivers are used:
•
•
•
In Canada, the 5882H receiver must be used.
Action
At the control unit, make sure the power switch is in the "OFF" position.
Run the buses as required and make sure to appropriately tag them. Limit each RS-485
bus to a single wire run.
Note: It is important to appropriately tag the cables so they can readily be identified.
This is especially important if troubleshooting becomes necessary at some future date.
Run the cable through the side opening of the housing unit. Cut the cable and remove
enough sheathing and insulation from each wire to allow fastening under the pressure
plates of TB1.
Measure the resistance between the black and red conductors (the (+) lead of the meter
to the red conductor and the (-) lead to the black conductor). A reading of less than 12
ohms indicates a short on the power conductors. Make the necessary corrections before
proceeding.
Connect the RS-485 cable to TB1 of the gateway. Identify terminal wires so that the
proper wires can be connected to each terminal. See Figure 5-16.
Connect the RS-485 bus cable to the control unit (see table below).

Remove jumper P1 unless the RF gateway module is to be located at the end of the RS-
485 bus; in that case, leave the jumper on.
Each must be at least 10 feet from the other, as well as from the control panel and remote
keypads.
Using two receivers does not increase the number of RF points that the system can support.
