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 and runs on a Notifier intelligent fire system (using a compatible proprietary communication protocol). It is a multi-criteria smoke and heat detector (58°C Rate-of-Rise). An infra- red sensor adds further detection ability and increased immunity to false alarms. The sensor plugs into the B501RF wireless sensor base.
