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.

881 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.

882 Model 882 is a 2-wire conventional photoelectronic smoke detector that use a state-of-the-art optical sensing chamber.

This detector is designed to provide open 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 are designed to provide open area

protection and to be used with compatible UL listed panels only.

The 800 series are UL listed.
