System Sensor of St. Charles, Ill., releases the 5151 heat detector, a conventional, two-wire device.
The product 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 also 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, according to the company.
