The fire smoke optical point detector SPD-3.10 is designed for the detection of ignitions in enclosed premises of buildings and constructions and reacts on the appearing of low concentrated smoke, for the indication of this status and for the transmission the “Fire” signal to the control panel.

The detector is counted on the continuous 24-hour operating in common with a control panel by a 2-wire or 4-wire fire alarm loop.

The connection of the detector to the control panel is realized by means of bases B01, B1. The connection of the detector to the control panel with the 4-wire matching loop is realized by means of bases B2, B3, B4, and B5. Bases B6, B7, B8, and B9 are terminal, mounted by one at the end of each loop and used in the 4-wire matching loop for the control of feeding voltage presence and the circuit integrity.

The detector can be connected to the control panel with the 4-wire matching loop with the help of bases B01, B1, and besides loop matching modules MUSH-1, MUSH-2 and others should be used.

The detector has functions of standby mode indication and the serviceability testing.
