NRX-TDIFF
AND
DESCRIPTION
These heat sensors are battery operated RF devices designed for
use with the NRXI-GATE radio gateway. They contain a wireless
40°C
transceiver and run on a Notifier addressable fire system (using a
compatible proprietary communication protocol).
-30°C
The NRX-TFIX58 provides fixed 58
The
NRX-TDIFF
temperature sensing (A1R).
The sensors plug into the B501RF wireless base.
These devices conform to EN54-25 and EN54-5 (classes A1S
and A1R). They comply 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 installation of the B501RF base.
Spacing between radio system devices must be a minimum of 1m
Figure 2 details attaching the sensor head to the base.
Anti-Tamper Features
The base includes a feature that, when activated, prevents removal
of the sensor from the base without the use of a tool. See Figures
3a and 3b for details on this.
Head Removal Warning - An alert message is signalled to the CIE
via the Gateway when a head is removed from its base.
Figure 4 details the battery installation and the location of the rotary
address switches
Batteries should only be installed at the time of commissioning
Using these battery products for long periods at
temperatures below -20°C can reduce the battery life
Observe the battery manufacturer's precautions for use and
SETTING THE ADDRESS
Set the loop address by turning the two rotary decade switches
on the underside of the sensor (see figure 4), using a screwdriver
to rotate the wheels to the desired address. The device will take
one sensor address on the loop. Select a number between 01 and
159 (Note: The number of addresses available will be dependent
on panel capability, check the panel documentation for information
on this).
PROGRAMMING
To load network parameters into the RF sensor, it is necessary to
link the RF gateway and the RF sensor in a configuration operation.
At commissioning time, with the RF network devices powered
