Photo Thermal Fire Detector

The NRX-OPT smoke detectors are a battery powered radio-frequency device, designed to be used with the NRXI-GATE radio gateway. It contains a transceiver and is integrated into a fire-fighting system that can be addressed through a proprietary communication protocol.

The unit is an optical smoke detector and should be fixed to the ceiling via the B501RF base. Standby current: 120 μA to 3 V DC (typical in normal operation mode). Red LED Current: 4mA max. Resynchronization time: 35 s (maximum 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% to 93% (no condensation).

• Mesh multiple communication paths for increased reliability
• 18RF channels at 868MHz - provides greater tolerance to interference
• 2 integrated antennas on each wireless fire device – easier positioning of devices
• Up to 400 m free air communication range – providing good coverage levels
• Average 5 year battery service life – reducing maintenance requirements
• Addresses set using rotary switches – reduced commissioning time
• Loop powered Gateway – reduced installation cost and time
• Up to 8 Gateways per loop
• Up to 32 Wireless devices per Gateway

• CE
