GST DI-9101E Intelligent Optical/Heat Multi-Sensor

The GST DI-9101E is an intelligent addressable multi-sensor detector combining photoelectric smoke detection with fixed-temperature and rate-of-rise heat detection. It works on the loop of GST addressable panels such as the GST100, GST200N, GST-IFP4E and GST-IFP8, and is LPCB approved to EN 54-7 and EN 54-5.

Key features

• Combined optical smoke and heat sensing for a wider range of fires
