The Simplex 4098-9778 is an addressable heat sensor in a black housing for the Simplex TrueAlarm fire alarm family. Specifically, the queue identifies it as an “SSD heat sensor, black.”
First, the sensor monitors the temperature in its protected area. Then it reports back to a compatible Simplex addressable fire alarm control panel.
How the Simplex 4098-9778 Detects Heat
Heat detectors fit areas where smoke detection is not practical. In addition, dirty environments, kitchens, garages, and storage rooms commonly use heat sensors instead of photoelectrics.
Therefore the 4098-9778 covers those spaces on Simplex jobs. As a result, the addressable panel can still see the exact sensor reporting, even when smoke detection is the wrong technology.
Where the 4098-9778 Is Used
You will see the 4098-9778 on Simplex TrueAlarm addressable systems. Furthermore, the black housing is typical for installations where the standard white finish is not desired for aesthetic or environmental reasons.
