About the 4098-9755
The 4098-9755 is an addressable air duct smoke sensor housing with a factory-installed 4098-9714 TrueAlarm photoelectric sensor. Sampling tubes draw duct air past the sensor; the panel reads its analog value, sets the sensitivity (0.2% to 3.7% per foot) and tracks dirt build-up. This basic model has no relay output and is powered from the IDNet or MAPNET II loop.
A sampling tube sized to the duct width (4098-9854 to 4098-9858) must be ordered separately, and duct smoke detection does not replace smoke detection in open areas.
