The MICROISA 12P is a compact device , reliable and integrated in the electric board. The device is provided with a supervision system that controls up to 12 optoinsulated input (they can operate with NO or NC contacts) and it manages two relays outputs, one for acoustic alarm and other one for the load.
Even if only one alarm goes off, both output relays are switched on and the relevant led on the front of the panel lights up. The type of alarm sequence desidered (isa/a/m/r8/f1) can be selected by using a dip switch positioned on the back of device.
Upon request we can supply R12 unit , which is able to manage a remote repetition relay (No-cNc) for each alarm point.
More than one MICROISA 12 P can be interconnected.
