100 Series™ Plug-In Thermal Detectors System Sensor 100 Series Plug-in Thermal Detectors offer superb performance and reliability in a sleek, low-profile design. Features • Low standby current • Compatible with 400 Series product • Two visible LEDs “blink” in standby and provide a 360° field viewing angle • Detector head plugs easily into base • Built-in test switch • Wide variety of mounting bases with built-in shorting spring 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. A full line of accessories are available for this product.
