Description
The Simplex 4098-9773 Carbon Monoxide Detector Base combines advanced carbon monoxide (CO) detection with the reliability of TrueAlarm addressable technology. Designed for use with compatible TrueAlarm sensors, this base features an integrated 520 Hz low-frequency sounder, ideal for applications requiring compliance with life safety codes such as NFPA 72 and UL 2075.
Utilising a precision electrolytic CO sensing module, the 4098-9773 continuously monitors ambient CO levels and can intelligently combine this data with photoelectric or heat sensor information to detect early-stage fire conditions or prevent nuisance alarms. The system’s addressability ensures that each base retains its programmed location address even when the sensor head is replaced or removed for servicing.
With support for both standalone CO detection and multi-sensor analysis, the Simplex 4098-9773 provides reliable protection from carbon monoxide hazards and enhances fire detection accuracy by evaluating environmental data from multiple inputs.
This detector base supports system-wide communication and testing, includes a front-accessible address selector under the removable sensor, and provides visible LED indicators for power, alarm, and trouble status.
