Mini Door Contact (MDC-3) User Manual
The Mini Door Contact monitors the opening/closing of specified devices (e.g. door or window). The Door Contact is fixed to the
monitored device frame with an actuating magnet fixed to the device. When the door or window opens, the magnet moves away
from the Door Contact, activating an internal magnetic switch causing the Door Contact to transmit alarm signal to the Control
Panel. The device also has the capabilities of communicating signal problems along with low battery situations.
The Door Contact design is consisted of a front cover and a back cover. The front cover(back) contains all electronics and the
back cover provides a means for fixing the device. An enclosed PCB tamper switch provides tamper protection against
unauthorized device opening.
