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.
