The fire smoke optical point detector SPD-3.1M is designed for the detection of ignitions in enclosed premises of various buildings and constructions which are accompanied with the appearing of smoke and for the transmission the “Fire” signal to a control panel. The detector is counted on the continuous operation along with a control panel by a 2-wire fire alarm loop with the nominal voltage of the loop power voltage 12 or 24 V.
Detectors SPD-3.1M can be completed with the base B103-01, which has an additional free contact (the screw joint) “5”. This contact is meant for the ease of assembling terminal (Rterm) and limiting (Rlim) resistors.
The loop matching module MUSH-2 is applied for the connection of detectors to a control panel with the 4-wire connection scheme of detectors.
