The Simplex 4098-9791 is a TrueAlarm® analog addressable sensor base that adds an isolated relay contact output to standard detector installations. When the sensor head mounted to the 4098-9791 goes into alarm, the onboard relay activates, providing a dry contact that can control HVAC equipment, magnetic door holders, fan shutdown systems, or other ancillary devices.
The 4098-9791 connects to IDNet or MAPNET II addressable loops and accepts standard TrueAlarm sensor heads, making it a flexible solution for installations requiring local relay action without additional relay modules.
- Relay output: Isolated dry contact, activates on sensor alarm
- Applications: HVAC shutdown, door release, ancillary control
- Loop interface: IDNet / MAPNET II addressable
- Compatible heads: Standard TrueAlarm analog sensor heads
- Form factor: Standard 4-inch detector base footprint
The 4098-9791 sensor base eliminates the need for separate relay modules in spaces where local control action is required at the point of detection, simplifying installation and reducing panel wiring. A reliable choice for Simplex TrueAlarm® addressable systems.
