DESCRIPTION

The NRX-M711 radio input-output module is a battery operated RF device designed for use with the NRXI-GATE radio gateway, running on an addressable fire system (using a compatible proprietary communication protocol). It is a dual module having separate input and output capability, combined with a wireless RF transceiver and is supplied with a wireless back box. This device conforms to EN54-18 and EN54-25. It complies with the requirements of 2014/53/EU for conformance with the RED directive

INSTALLATION

This equipment and any associated work must be installed in accordance with all relevant codes and regulations

Figure 1 details the dimensions of the back box and cover.

Spacing between radio system devices must be a minimum of 1m

Table 1 shows the wiring configuration of the module

Table 1: Terminal Connections

TERMINAL	CONNECTION / FUNCTION

Input Module requires 47K EOL for normal operation.
Output Module requires 47K EOL at the load for norma operation in supervised mode.
If the load is a low impedance (compared to the EOL) a
series diode should be added for correct load supervision (see Figure 2 for diode polarity).

Figure 4: Rear of Module with Battery Compartment and Cover

Figure 5: Front of Module with Address Switches

WARNING: Switching Inductive Loads

See Figure 3. Inductive loads can cause switching surges, which may damage the module relay contacts (i). To protect the relay contacts, connect a suitable Transient Voltage Suppressor (iii) – for example 1N6284CA – across the load (ii) as shown in Figure 3. Alternatively, for unsupervised DC applications, fit a diode with a reverse breakdown voltage greater than 10 times the circuit voltage. Figure 4 details the battery installation and Figure 5 the location of the address switches

Important
Batteries should only be installed at the time of commissioning Warning Observe the battery manufacturer’s precautions for use and requirements for disposal

Possible explosion risk if incorrect type is used Do not mix batteries from different manufacturers. When changing the batteries, all 4 will need to be replaced Using these battery products for long periods at temperatures below -20°C can reduce the battery life considerably (by up to 30% or more)

Fixing the module: Remove the 2 screws from the front cover to reveal the RF module. Remove the RF module from the back box (see below). Screw the back box to the desired position on the wall using the fixings provided. Refit the module in the box (see below). Wire the plug-in terminals as required by the system design. Refit the front cover to protect the module. Removing the module from the back box: Slacken off the 2 fixing screws, twist the module clockwise slightly and lift out. Reverse this process to refit the module. Device Removal Warning: In a working system, an alert message will be sent to the CIE via the Gateway when the front cover is removed from the back box

SETTING THE ADDRESS

Set the loop address by turning the two rotary decade switches on the front of the module using a screwdriver to rotate the wheels to the desired address. Except when Advanced Protocol (AP) is being used (see below) the dual I/O module will take two module addresses on the loop; the input module address will be the number shown on the switches (N), the output module address will be incremented by one (N+1). So for a panel with 99 addresses, select a number between 01 and 98. In Advanced Protocol (AP) addresses in the range 01-159 are available, depending on panel capability (check the panel documentation for information on this).

LED INDICATORS

The radio module has a tri-colour LED indicator that shows the status of the device (see Table 2):

Table 2: Module Status LEDs

Module Status	LED State	Meaning
Power-on initialisation (no fault)	Long Green pulse	Device is un-

commissioned (factory default)
3 Green blinks| Device is commissioned
Fault| Blink Amber every 1s.| Device has an internal trouble

Un-commissioned

| Red/Green double-blink every 14s (or just Green when communicating).| Device is powered and is waiting to be programmed.
Sync| Green/Amber double-blink every 14s (or just Green when communicating).| Device is powered, programmed and trying to find/join the RF network.
Normal| Controlled by panel; can be set to Red ON, Green ON, periodic blink Green or OFF.| RF communications is established; device is working properly.
Idle

(low power mode)

| Amber/Green double-blink every 14s| Commissioned RF network is in standby; used when the gateway is powered off.

PROGRAMMING AND COMMISSIONING Configuring the Output Module Mode

The output module is supplied configured as a Supervised Output Module (factory default setting). To change the output to relay mode (Form C – volt- free changeover contacts) requires a separate programming operation using the Device Direct Command in AgileIQ (See Radio Programming and Commissioning Manual – ref. D200- 306-00 for details.)

Starting with an un-commissioned module

Remove it from the back box.
Ensure that the address is set to 00 (default setting).
Insert the batteries.
Select the Device Direct Command tab in AgileIQ.
Double click on the screen to reveal the list of options and follow the instructions to configure the output module mode.

Note: Remove the batteries from the device afterwards if the system commissioning operation is not about to be done. It is recommended that the output module configuration is noted for future reference on the module label after commissioning:

Commissioning

Remove the module from the back box.
Ensure that the correct address has been set.
Insert the batteries.
Refit the module and replace the back box front cover

the RF gateway and the RF module in a configuration operation using the AgileIQ software tool. At commissioning time, with the RF network devices powered on, the RF gateway will connect and program them with network information as necessary. The RF module then synchronises with its other associated devices as the RF mesh network is created by the Gateway. (For further information, see the Radio Programming and Commissioning

NOTE: Do not run more than one USB interface at a time to commission devices in an area. WIRING DIAGRAMS
