??212-43?? "???-43??" self-contained smoke detectors optical-electronic point fire detectors

Autonomous detector powered by four AAA elements. Designed to detect fires accompanied by the appearance of smoke. Autonomous detectors DIP-43MK by design and basic technical characteristics are full analogues of IP212-43M "DIP-43M" and differ only by the presence of an additional optorelay output, whose contacts are galvanically isolated from the circuit and detector power supply elements. In ??212-43?K an optorelay with normally open (closed) contacts is used. When using the detectors IP212-43MK the presence of an additional optorelay output allows to organise the transmission of the triggering signal to the alarm control panels via two-wire alarm loops. At the same time, such use of detectors does not exclude the possibility of combining them into a group of up to 50 pieces using a separate loop.
