NRX-SMT3
DESCRIPTION
The NRX-SMT3 radio sensor is a battery operated RF device designed for
use with the NRXI-GATE radio gateway. It contains a wireless transceiver
40°C
and runs on a Notifier addressable fire system (using a compatible
proprietary communication protocol).
It is a multi-criteria smoke and heat detector (58
-30°C
sensor adds further detection ability and increased immunity to false alarms.
The sensor plugs into the B501RF wireless sensor base.
This device conforms to EN54-25, EN54-5 (Class A1R) and EN54-7. 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 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 considerably (by up to 30% or more)
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 on, the RF gateway will
connect and programme them with network information as necessary. The
RF sensor 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 Manual - ref. N200-306-00.)
NOTE: Do not run more than one interface at a time to commission
devices in an area.
