RX1: Wireless Receiver   

V1.0

Specifications

Location

The location of the RX1 affects its performance. In order to ensure the best 
possible signal reception, the following list of location criteria should be 
respected:

• Select an installation site that is free of obstacles that reflect and absorb radio 

frequency (RF) signals, as well as interference that may distort signals. Avoid 
installation near or in the path of strong RF fields (e.g., neon lights, 
computers), on or near metal objects, circuit breaker boxes, air conditioners, 
or heating ducts since they may cause interference and reduce the module’s 
sensitivity.

• Mount the RX1 as high as possible.
• Avoid mounting the RX1 in the basement as the range of the module is 

reduced when mounted below ground level. If it is absolutely necessary to 
mount the module in the basement, mount the module as high and as close 
to the underside of the first floor as possible.

Installation

Only one RX1 module can be connected to 
an E55 or SP Series panel (V5.0 and higher). 

To connect the RX1 to the control panel:

1. Straighten the RX1 antenna for maximum 

reception.

2. Create a 4-wire bus connection to the 

control panel, as shown.

3. If the current draw exceeds 150mA on 

PGM1 or PGM2, use a relay. 
To add a relay, connect the RX1’s “R” 
terminal to the relay’s “RED” terminal. 
Connect the PGM terminal (PGM1 or 
PGM2) to the relay’s BLK terminal.

Description

The RX1 Wireless Receiver 
adds wireless receiving 
capability to the E55 and SP 
Series panels (V5.0 and 
higher). Adding the RX1 to an 
installation allows for the use 
of REM1/RAC1 remotes as 
well as wireless one-way zone 
transmitters (SP Series only) 
with the system.

Features

• Up to 32 remote controls
• Up to 32 wireless zones (SP Series only)
• 2 PGM outputs follow buttons 1 and 2 on 

REM1/RAC1 (also programmable 
through control panel)

• 4-wire bus connection
• Feedback LEDs (Bus / RX)
• In-field firmware upgradable 
• Compact design
• RF jamming supervision
• Low battery, tamper and check-in 

supervision

• Transmitter signal strength display
