Natron SD

Wireless optical-smoke detector, compatible with both – Natron WE-A and Natron WE-C wireless gateways. The signal coverage of the Natron SD reaches up to 1500 (in open area), thanks to our bidirectional wireless communication protocol – Beacon+. The protocol efficiency also contributes to the exceptional battery life that could last to up to 10 years, with 2x CR123A type of batteries. The Natron SD is also equipped with an internal buzzer, used for local sound signaling in case of detector activation (fire condition), as well as build-in tamper switch.
