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 thermistor heat sensing circuit that provides maximum performance and solid-state reliability. It initiates an alarm in response to rapid rate-of-rise (increases in excess of 15°Fper minute) and fixed heat (135°F) conditions. This enables the 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.
The detector also provides other key features, including a recessed mounting option, a variety of mounting bases, and a full line of optional accessories. S2101 OB3AO.
