Sell 5151 Rate of Rise / Fixed Heat Detector

Specification of

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 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 Rise, providing a timely response to both rapid and slow temperature increases.
