KFDDC Radio Frequency Door Contact Alarm Transmitter

The KFDDC is a small battery-powered door and window contact. Fit the magnet and sensor either side of the opening and it sends a radio signal to a compatible receiver whenever the door or window opens. No cabling, no drilling through walls, just a quick fix with adhesive pads or screws. It is a cost-effective way to monitor front doors, fire exits, patio doors or medicine cupboards in care homes, sheltered housing or private homes where someone may be at risk of wandering.
