Natron MD

Wireless combined detector, compatible with both – Natron WE-A and Natron WE-C wireless gateways. Natron MD combines an optical-smoke and a thermal/heat detection parts. The signal coverage of the Natron MD reaches up to 1500 (in open area), thanks to our bi-directional wireless communication protocol – Beacon+. The protocol efficiency also contributes to the exceptional battery life that could last to up to 10 years, with 3x CR123A type of batteries. The Natron MD 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.
