The System Sensor 5621 2-Circuit Heat Detector intended for use in HVAC systems. It works by detecting a fixed temperature of 135°F and is, therefore, suitable for areas that cannot be used due to dust or steam. It has heat-sensitive element that triggers when the set limit is attained to prevent the occurrence of fire conditions. Often used as a replacement for rooftop units, furnaces, and air handlers, this equipment is safe, easy to integrate, and provides reliable protection for commercial and industrial systems.
