Marketing Information

The HDX Series Rate-of-Rise and Fixed-Temperature Sensors from Interlogix® offer an effective fire safety solution for environments with high likelihood of rapid fire development, like a kitchen or utility room, or where optical smoke detectors cannot function effectively due to high dust conditions, like in a laundry room, garage or attic. These sensors are designed to monitor the room temperature and activate an alarm if the temperature gets too high or rises rapidly. A model is available that also activates a separate freeze alarm if the temperature drops below a specified point.

HDX Series sensors use electronic processing to detect both heat and freeze conditions using a learn mode wireless transmitter. The micro-processor trips the transmitter when the temperature at the sensor location reaches a fixed temperature of 135°F (57°C), 200°F (94°C) or 41°F (5°C), depending on the model installed. The sensor will also be activated if the temperature increases at a rate equal to or higher than 12°F (6.7°C) per minute. If activated, all three elements (rate-of-rise, fixed temperature, freeze) of the HDX Series sensors are self-restoring when the alarm condition has been removed.
