Description
The Simplex 4098-9733 is a TrueAlarm analog addressable heat sensor designed for use with compatible Simplex IDNet or MAPNET II fire alarm control units. It digitally transmits analog temperature data to the control panel, where alarm decisions are made based on programmable fixed temperature and optional rate-of-rise criteria.
The sensor provides selectable fixed temperature operation at 135°F (57.2°C) or 155°F (68°C), with optional rate-of-rise detection selectable at 15°F or 20°F per minute (8.3°C or 11.1°C per minute). The device is self-restoring and uses rate-compensated sensing for accurate local temperature measurement.
TrueAlarm processing at the control unit includes peak value logging, environmental compensation, and NFPA 72 compliant sensitivity monitoring. The sensor mounts to compatible 4098-series TrueAlarm bases (sold separately).
