Description

Overall, the System Sensor 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. Also, additional key features include a recessed mounting option; a variety of mounting bases, and a full line of optional accessories.

In general, this System Sensor 5451 detector contains a unique dual thermistor 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°F per minute) and fixed heat (135°F). 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 rising; providing a timely response to both rapid and slow temperature increases.
