5151 SYSTEM SENSOR

Product Overview

The System Sensor 5151 is a plug-in thermal detector from the 100 Series, combining reliability, quick response, and a low-profile design. It is ideal for applications where rapid temperature changes indicate a fire emergency. This detector responds to both fast rate-of-rise conditions (temperature increases over 15°F per minute) and fixed heat at 135°F, allowing it to signal the control panel before reaching its fixed threshold during rapid temperature spikes. This ensures a timely response to both slow and fast temperature increases. A wide selection of accessories is available to support flexible installation and system integration.
