The 800 series are 2-wire conventional low profileplug-in detectors designed to meet theperformance criteria designated by UL. It is a low cost and high reliabilityseries. A LED will be latched on to locally indicate alarm. The in (-) and out(-) terminals are short-circuited inside the detectors. When the detector ismounted , it will continue the wire to the next device or EOL resistor. When itis removed, the wire will be open for wiring supervision.
881 Model 881 is a 2-wire conventional ionization smokedetector that uses a state-of-the-art sensing chamber. These detectors aredesigned to provide open area protection and to be used with compatible ULlisted panels only.
882 Model 882 is a 2-wire conventional photoelectronic smoke detector that use astate-of-the-art optical sensing chamber. This detector is designed to provideopen area protection and to be used with compatible UL listed panels only.
885 Model 885 is a 2-wire conventional fixed temperature heat detector. These detectors aredesigned to provide open area protection and to be used with compatible ULlisted panels only.
The 800 series are UL listed.
