SPD-3.3. Products. Arton

The fire combined Heat Smoke Detector SPD-3.3 is designed for the detection of ignitions in enclosed premises of different buildings and constructions which are accompanied with the appearing of smoke as well as of the exceeding the threshold value of ambient temperature and for the transmission “Fire” signals to control panels.

The detector is counted on the continuous 24-hours operation along with a fire-intruder control panel by the 4-wire connection scheme of detectors with the nominal voltage of loop supply 12 V.

The detector has functions of standby mode indication (a red LED flashing).

The detector can be completed with the module M-1 for the control of loop power voltage and for the installation of a terminal resistor.
