Siemens DLH1191A Linear Smoke Detector Heater
Product Code: DLH1191A
The DLH1191A heater ensures the linear smoke detector continues to operate in environments with condensation risk. Moisture accumulating on the optical surface causes light attenuation and the system to respond as if smoke is present; the heater prevents this condensation. It requires external DC 24 V power supply to operate. It is used in cold storage facilities, enclosed parking garages, and semi-open spaces.
