4098-9751 SIMPLEX, SSD IN-DUCT SENSOR HOUS W/REL.
Model 4098-9751 Simplex provides a local relay:
- Relay operation is programmable from fire alarm control panel and is rated: 1 A @ 28 VDC, power limited; or 1/2 A @ 120 VAC, non-power limited
- 24 VDC power is supplied by fire alarm system (4-wire operation)
HVAC air ducts in buildings supply fresh air and exhaust stale air. Depending on the overall fire detection requirements, smoke detection may be required in the air ducts. For applications where sampling tube type duct detection is not appropriate due to low air velocity or small duct size, Simplex® model 4098-9750 and 4098-9751 housings can be used to install the Simplex model 4098-9714 TrueAlarm analog sensor directly in the duct.
Application. These housings mount a spot-type smoke sensor directly into the duct airflow. Proper application requires controlled dust and humidity.
4098-9751 Relay Model.
Model 4098-9751 provides a relay that can be programmed to track the local sensor’s operation or can be independently controlled by the fire alarm control panel to perform fire response actions such as fan shutdown and damper control.
Please note that smoke detection in air ducts is intended to notify of the presence of smoke in the duct. It is not intended to, and will not, replace smoke detection requirements for open areas or other non-duct applications
