5151 Plug-In Thermal Detector

5151 plug-in thermal detectors meet the needs for applications where rapid response is vital and rapid temperature increases would only be caused by a fire emergency. The detectors initiate an alarm in response to both rapid rate-of-rise conditions (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 setpoint for high rates-of-rise, providing a timely response to both rapid and slow temperature increases.
