The air duct smoke detector shall be a system sensor innovairflex d4120 photoelectric duct smoke detector.
System sensor d4120 smoke head.
Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.
A plug in duct sensor head offers improved false alarm immunity and simple installation testing and maintenance.
These actions can facilitate the management of toxic smoke and fire gases throughout the areas served by the duct system.
Model d4120 and d4s duct smoke detectors utilize 4 wire photoelectric tech nology for the detection of smoke.
Smoke is sensed an alarm signal is initiated and appropriate action can be taken to shut off fans blowers change over air handling systems etc.
This unit senses smoke in the most challenging conditions operati ng in airflow speeds of 100 to 4 000 feet per minute temperatures of 4ºf to 158ºf and a.
This duct detector unit senses smoke in the most challenging conditions operating in airflow speeds of 100 to 4 000 feet per minute temperatures of 4ºf to 158 f and a humidity range of 0 to 95 percent non condensing.
The innovairflex d4120 4 wire photoelectric duct smoke detector features a pivoting housing that fits both square and rectangular footprints and mounts to round or rectangular ductwork.
