About this product
Plug-in heat detector head from System Sensor's 100 Series, with a 135°F fixed alarm point plus rate-of-rise sensing above 15°F per minute. The head is sold alone and mounts on a 100 or 400 Series base.
Rate-of-rise lets it alarm on a fast fire before the room reaches 135°F. Spacing is 50 ft (2,500 sq ft) on smooth ceilings, standby draw is only 80 µA, and two LEDs blink in standby for 360° visibility.
Photos show the head installed in a base for reference. The base is not included. Install, program and test per NFPA 72 and local code.
