Description
5151 System Sensor Plug-in Heat Detectors Offer Superb Performance and Reliability in a Sleek, Low-Profile Design.
The 5151 System Sensor thermal detector meets the needs of 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 Rising, providing a timely response to both rapid and slow temperature increases. A full line of accessories is available for this product.
