About the 4098-9733
Self-restoring analog heat sensor head that mounts on a TrueAlarm sensor base and reports the local temperature to the fire alarm panel. The panel sets a fixed alarm temperature of 135°F or 155°F (57.2°C or 68°C), with or without rate-of-rise detection at 15°F or 20°F per minute. It can also be programmed as a utility sensor for 32°F to 155°F (0°C to 68°C) to give freeze warnings or flag HVAC problems.
Smoke and toxic gas can reach hazardous levels before a heat sensor alarms; smoke detection is recommended where life safety is a factor.
