NOTIFIER NRX-OPT OPTICAL SMOKE SENSOR

The NRX-OPT optical 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 firefighting system using a proprietary communication protocol. The unit is an optical smoke sensor and must be fixed to the ceiling through the B501RF base. Standby current. 120 μA at 3 VDC (typical in normal operating mode). Red LED current. 4mA 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).
