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.
