The 5151 is a two-wire detector designed to provide open area protection.

System Sensor announced the launch of its new conventional, two-wire heat detector, the 5151. The device is a combination fixed and rate-of-rise thermal detector designed to provide open-area protection with 50-foot spacing capability as approved by UL 521. For local alarm indication, it includes two LEDs on each detector for full 360° visibility.

The 5151 replaces the 5451 heat detector and carries the same electrical properties in a newer, more modern package. The new housing matches other System Sensor conventional products, enabling you to provide your customers with a consistent look throughout their facilities.
