Mini Door/Window Contact Manual AC-MDC
The Mini Door/Window Contact monitors the opening/closing of specified doors
and windows and is fixed to the monitored device frame with a magnet fixed to
the device. When the door or window opens, the magnet moves away from the Mini
Door/Window Contact, activating an internal magnetic switch causing it to
transmit an alarm signal to the Sync Hub. The device also has the capabilities
of communicating signal problems along with low battery occurrences.
The Mini Door/Window Contact design consists of a front cover and a back
cover. The front cover contains all electronics and the back cover provides a
means for fixing the device. An enclosed PCB tamper switch provides tamper
protection against unauthorised device opening.

Features
LED Indicator
In Normal Operation Mode, the LED indicator remains off except in the
following situations:
- When Mini Door/Window Contact’s Tamper switch is triggered.
- When the Mini Door/Window Contact is activated with either Tamper or Low battery condition.
- When the Mini Door/Window Contact is activated and transmitting the signal under the Test mode.
Supervision
- The Mini Door/Window Contact will automatically transmit Supervisory signals periodically to the Sync Hub at random intervals of 90 to 110 minutes in Normal Operation Mode.
- If the Sync Hub has not received the signal from the Door Contact for a preset period of time, the Sync Hub will indicate that particular Mini Door/Window Contact is experiencing an out-ofsignal problem.
Tamper Switch
The tamper switch is designed to protect against unauthorised cover opening.
When the tamper is triggered, Mini Door/Window Contact will emit a signal to
the Sync Hub for reporting, the LED will also light up.
Battery
The Mini Door/Window Contact uses one 3V CR2450 Lithium battery as its power
source. It is also capable of detecting low battery. When the battery is low,
a low battery signal will be sent to the Sync Hub along with regular
transmission. The LED will light up when the Mini Door/Window Contact is
activated under low battery status.
