Earlier Alarm, Faster Fire-fighting, Less Loss.
1. Overview
The explosion-proof smoke detector OT101Ex has division and zone explosion-proof ratings and is suitable for industrial and commercial applications. It is designed to operate effectively with smoldering and rapidly growing fires. The detector includes a smoke sensor module which is intrinsically safe, and an explosion proof integrated junction box. The detector outputs include a localized LED and a fire relay.
