NOTIFIER NRX-SMT3 TRIPLE TECHNOLOGY SMOKE SENSOR

The NRX-SMT3 triple technology smoke sensor is a battery-powered radio frequency device designed to be used with the NRXI-GATE radio gateway. It contains a transceiver and is integrated into an addressable fire system using a proprietary communication protocol. The unit detects smoke and heat (such as a 58°C thermovelocimetric detector). An infrared sensor integrates the detection capability and increases immunity to false alarms. The sensor is attached to the ceiling using the B501RF base. The device complies with EN54-25. EN54-5 (Class A1R) and EN54-7. and complies with the requirements of the EN 300 220 and EN 301 489 standards for compliance with Directive R and TTE. Standby current. 120 μA at 3 VDC (typical in normal operating mode). Red LED current. 4 mA max. Resynchronization time. 35 s (max time from turning on the device to normal RF communication when the network is active) Batteries. 4 Duracell Ultra 123 Battery life. 4 years at 25oC Radio frequency. 865-870 MHz. RF output power. 14 dBm (max) Range. 500 m (typical in free air) Relative humidity. 10 percent to 93 percent (without condensation).
