The sensor uses optical technology for smoke detection, which provides rapid and reliable response in the event of a fire. This technology is particularly suitable for environments where early smoke detection is critical to ensure the safety of people and structures. Radio frequency communication, via the NRXI-GATE gateway, ensures that the system operates smoothly and without interruption.
The sensor is designed for easy ceiling installation due to its compatibility with the B501RF base. With compact size and light weight, the sensor integrates seamlessly into any environment without compromising the aesthetics or functionality of the fire alarm system. Wireless communication technology further reduces installation complexity and improves overall efficiency.
With a battery life of up to 4 years, the sensor provides continuous operation without the need for frequent battery replacement. The standby current is low (120A), ensuring optimal energy management. In addition, the device has a fast resynchronization function, minimizing downtime and improving overall system reliability.
The sensor complies with EN54-25 and EN54-7, which regulate firefighting devices and ensure excellent performance in terms of safety and reliability. Compliance with R&TTE directives ensures that the device meets European safety standards for radio communications.
