A30XTA Cofem

Algorithmic addressable heat sensor for fire detection.

The A30XTA sensor is based on the physical properties of a NTC.  The variation of the electrical features of the NTC thermistor due to variation of room temperature makes it suitable for a heat sensor.

The A30XTA is capable of registering absolute temperatures (heat sensor) but also temperature rises (rise of heat rate sensor).

The heat rate function allows detect a fire in the first phases of its growth.  If it is very slow, the sensor is activated when temperature reaches 55ºC.
