About the 4098-9756
The 4098-9756 is an addressable duct smoke sensor housing with a factory-installed 4098-9714 TrueAlarm photoelectric sensor. It samples air in air conditioning or ventilating ducts and sends analog smoke values to the panel over IDNet or MAPNET II. It also has a supervised output for up to 15 remote 4098-9843 relays under panel control; it needs separate 24 VDC and comes with one relay.
Order a sampling tube for the duct width separately; the relay output needs separate fused 24 VDC from the fire alarm power supply.
Specifications
