Cofem A50HI Addressable Heat Detector with Isolator

A50HI is an algorithmic addressable heat detector combining a rate-of-temperature-rise sensor (thermovelocimetric) with a short circuit isolator. It is used in spaces such as kitchens, boiler rooms, and parking garages where smoke produces false alarms. The built-in isolator ensures that the rest of the line continues to operate when a short circuit occurs in the loop.
