The Simplex 4098-9688 is a TrueAlarm® duct detector housing designed for surface-mount installation directly on HVAC supply or return air ductwork. The 4098-9688 housing accommodates TrueAlarm addressable sensor heads and uses sampling probes to draw duct air across the detector element, enabling early warning smoke detection in air handling systems per NFPA 72 and NFPA 90A.
The 4098-9688 represents the updated generation of the TrueAlarm surface-mount duct housing family, succeeding the 4098-9685. It connects to IDNet or MAPNET II addressable loops on Simplex fire alarm control panels.
- Mount style: Surface-mount on HVAC duct
- Sensor head: Accepts TrueAlarm addressable detector heads
- Sampling: Duct air sampling probes
- Loop interface: IDNet / MAPNET II addressable
- Generation: Updated/newer generation duct housing
- Application: Duct smoke detection per NFPA 72 / NFPA 90A
The 4098-9688 provides reliable duct smoke detection in a surface-mount form factor, making it a practical choice for new installations and retrofits on Simplex addressable systems requiring HVAC air duct protection.
