The 5151 is a combination fixed and rate-of-rise, plug-in heat detector.

The 5151 thermal detector meets the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire emergency.

The detector initiates an alarm in response to both rapid rate-of-rise conditions (increases in excess of 15F per minute) and fixed heat (135F). 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.
