Natron TD

Wireless heat detector, compatible with both – Natron WE-A and Natron WE-C wireless gateways. Natron TD supports two heat detection methods – fixed temperature and rate-of-rise types. The signal coverage of the Natron TD 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 a single CR123A type of battery. The Natron TD 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. Natron TD is designed for indoor installation.
