Fire Control Instruments has introduced the ADP Low-Flow Series photoelectronic air duct smoke sensors.

Fire Control Instruments (FCI), a part of Honeywell's Fire Group, has introduced the ADP Low-Flow Series photoelectronic air duct smoke sensors. The ADP series features low-flow technology that enables duct smoke detection throughout a broad range of airflow environments. The sensors detect smoke at air-speed velocities of 110 to 4,000 feet per minute. The ADP Series sensors operate by sampling air currents passing through the ducts. The sensors can shut down fans, blowers and air conditioning systems, preventing the spread of toxic smoke and fire gasses throughout the protected area. They are continuously monitored through a signaling line circuit. Any sensitivity in the sensors caused by dirt, temperature or humidity is reported to a panel, allowing compensation algorithms to maintain the set sensitivity and signaling the location of the problem.
