Two-wire Duct Smoke Detector

Smoke Sensor S6616 • PCB mounted photoelectric detector with onboard intelligence

• Environmental compensation with differential sensing for reliable, stable, and drift-free sensitivity

• Wide 0.79% to 2.46% obscuration/ft. smoke sensitivity Detector assembly

• Less than 2" deep for easy installation and applications where space is tight

• -4°F to 158°F (-20°C to 70°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

• On-board Alarm, Trouble, and Dirty LEDs

• Magnet-activated test switch • One Form C auxiliary alarm relay for controlling ancillary equipment (e.g., HVAC controls)

• Easy access to field connection terminals
