The Simplex 4098-9771 is an analog addressable carbon monoxide sounder base that integrates CO detection and local audible notification into a single unit. The 4098-9771 connects to IDNet or MAPNET II addressable loops, providing CO detection with an onboard sounder that activates upon detection of hazardous CO concentrations.
As the predecessor to the TrueAlarm ES 4098-9773, the 4098-9771 is suited for replacement and retrofit applications on existing Simplex IDNet and MAPNET II systems. Its combined sensor-sounder design reduces the number of devices needed in each protected space.
- CO detection: Integrated electrochemical CO sensor element
- Sounder: Integrated audible output activates on CO alarm
- Loop interface: IDNet / MAPNET II addressable
- Application: CO detection in commercial and light industrial occupancies
- Form factor: Standard addressable detector base
The 4098-9771 is a reliable CO sounder base for Simplex addressable systems requiring combined CO sensing and audible notification in a compact, low-profile form factor.
