VR Magnetic Contact. 2 input/output terminals. Brown color. Requires LR6 battery inc.Grade 2. Bidirectional wireless magnetic contact with two inputs/outputs (expansion via radio). The simple definition of magnetic contact is definitely not exhaustive for the MC300 device. In fact, MC300, in addition to providing two positions for the magnet, placed at 90 degrees with respect to each other, in order to facilitate the positioning of the device, also offers two programmable terminals as input or output. When the terminals are used as input, they allow the management of the usual zone types (NA, NC, single swing, double swing) and also allow direct connection of shutter detectors and vibration detectors. If used as output, they provide a open collector from 50 mA. The alarms coming from the magnetic contacts and individually from the two terminals are signaled separately in the control unit. For each device, it is possible to activate an option that transforms the unused magnetic contact, of the two present in the MC300, into a magnetic tamper. In this way, it is possible to detect sabotage attempts made with magnets. The device also has an anti-opening and anti-detachment device. MC300 is available in the colors white and brown.
