The 800 series are 2-wire conventional low profile plug-in detectors designed to meet the performance criteria designated by UL. It is a low cost and high reliability series.A LED will be latched on to locally indicate alarm. The in (-) and out (-) terminals are short-circuited inside the detectors. When the detector is mounted , it will continue the wire to the next device or EOL resistor. When it is removed, the wire will be open for wiring supervision. -Model 881 is a 2-wire conventional ionization smoke detector that uses a state-of the-art sensing chamber. These detectors are designed to provide open area protection and to be used with compatible UL listed panels only.
