Intelligent Addressable Optical Duct Detector

Less than 2" deep for easy installation and applications where space is tight
32 to 120 °F (0 to 50 °C) operating range with 100 ft/min. to 4,000 ft/min air velocity rating assures reliability under harsh environmental conditions
Status LEDs remain visible through clear assembly cover
Cover monitor switch for added security
Standard sampling tube spacing for easy drop-in migration from other detectors
Sampling tube can be installed with or without the cover in place and can be rotated in 45-degree increments to ensure proper alignment with duct airflow
15.2 to 19.95 Vdc operation
Magnet-activated test switch
One Form C auxiliary alarm relay for controlling ancillary equipment (e.g., HVAC controls)
No special tools required for easy access to field connections
Environmental compensation with differential sensing for reliable, stable, and drift-free sensitivity
Wide 0.79% to 2.46% obscuration/ft. smoke sensitivity
Identification of dirty or defective detectors
