摘要

The fire alarm base is arranged as a solid revolution and has the dielectric housing with diametrically located holes on it for attachment, a central hole for application of electric conductors and flexible flat cable elements and grooves for their attachment, orientation elements of corresponding base of the fire alarm head and cavities, wherein electrically conductive l-section spring planes are located and attached them with fixation elements on the housing in the corresponding cavities, consistent quantitatively and with location to corresponding channels of fire alarm head base and creates an electric couple on turn with them. It comprises less than one additional screw contact with a square nut and washer plate mounted on the electric housing in the corresponding rectangular groove in the distance from a screw contact of this base for power supply of fire alarms sufficient for a current-limiting resistor. The additional screw contact groove is divided by a partition with a hole into two parts.
