Edwards Signaling Intelligent Addressable Duct Smoke Detector. Less than 2 inch 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.
