1. LED indicator
2. Learn / Test button
This button is used for testing the radio
performance and for learning purpose.
3. Tamper Switch
The Tamper Switch protects the enclosure from
being opened or being removed from the
mounting surface.
4. Extension Terminal
In addition to the built-in magnet switch, you can
connect an additional “extension magnet switch”
or any device with N,C. (Normally Closed) dry
contact to this 2-pin terminal for installation
convenience.
5. Test / Normal Mode Jumper
(JP1)
This jumper is used to put the Open Contact in a
Test mode.
If the jumper is ON (the jumper is
inserted connecting the two pins), the
Open Contact is in Test mode.

6. Internal Magnet Switch Bypass
Jumper Switch. (JP2)
This 2-pin jumper switch is to select whether the
internal magnet switch is being used.
If the jumper is ON (the jumper link is
inserted connecting the two pins), the
internal magnet switch is bypass. Only
the device connected to the Extension Terminal
will activate the Open Contact.
If the jumper is OFF (if the jumper link
is removed or “parked” on one pin), the
internal magnet Switch is in use.

z LED Indicator
In Normal operation mode, the LED indicator will not
light except in the following situations:
z When the Open Contact is in Low battery
condition, every time the Open Contact is
activated (door opened or door closed), the
LED will light.
z When the cover is opened and the tamper
switch is violated, the LED will light.
z When the tamper condition persists, every
time the Open Contact is activated, the LED
will light.
However, if the Open Contact is in Test mode, the
LED will flash every time it is activated.
z Battery
The Open Contact uses one 1/2 AA, 3.6V Lithium
battery as its power source. The Open Contact will
have a typical battery life of over 3 years at an average
of 50 activations a day. Please note to always replace
battery with the correct size and voltage.
Low battery detection operates at a threshold of 3.2V
±5 % where the Open Contact has enough reserve
power to typically operate for 1 month before complete
exhaustion. When Open Contact is in low battery, the
LED will flash and a low battery signal will be sent to
the Control Panel along with regular signal
transmissions for the Control Panel to display the
status accordingly.
z Supervisory Signal
z After installation, the Open Contact will
automatically transmit Supervisory Signals
periodically to the Control Panel at intervals
of 30 min to 50 min randomly.
z If the Control Panel has not received the
signal from the Open Contact for a preset
period time, the Control Panel will indicate it
on its display to show that particular Open
Contact is experiencing an out-of-signal
problem.
z Getting Started
z Remove the fixing screw and cover assembly
z Insert the “1/2 AA” battery into the battery
holder taking care to connect the polarity
correctly.
z The LED indicator will flash briefly, then,
wait for 10 seconds.
z The Control Panel is already into into
“Device +/-“ menu and then select “Add
Device” menu.
z Press the test buttons inside the Open
Contact.
