Maximum and Differential Fire Heat Detectors IП102-1В1х2 for Fire Alarm Systems

The detectors ??102-1?2, ??102-1?1?2 are used as part of fire alarm systems and are designed to provide fire notification when the temperature of the controlled environment rises above the permissible temperature. Two-channel IP102-1B2 have two independent measurement channels in one housing and one thermal cable. The use of two channels will allow to implement the function of pre-warning, when the channels are set, for example, to two neighbouring classes (triggered one channel - "Attention", triggered the second channel - "Fire").

Two-zone detectors ??102-1?1?2 have two independent measurement channels in one housing, each measurement channel has its own cable temperature sensor. The length of the temperature sensors allows the detector housing to be installed outside the controlled area, for example, in a room with a lower probability of fire. Each of the two measurement channels can independently realise the functions of maximum, maximum-differential heat detectors.

The detectors can be used in hazardous areas of class 1 and 2..
