System Sensor 5451 Fixed/Rate-of-Rise, Plug-in Heat Detector

The 5451 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire emergency.

This detector contains a unique dual thermostat heat sensing circuit that provides maximum performance and solid-state reliability. It initiates an alarm in response to both rapid rate-of-rise conditions (increases in excess of 15 degreesF per minute) and fixed heat (135 degreesF). This enables the heat detector to communicate an alarm to the central control panel prior to reaching its fixed set point for high rates of rise, providing a timely response to both rapid and slow temperature increases. Additional key features include a recessed mounting option, a variety of mounting bases, and a full line of optional accessories.
