Smarthome SUPERVISED WIRELESS SECURITY CONSOLE PS561 - Manual (Page 10)

Windows
Note: For sliding windows it is best to
mount the magnet and switch at the
bottom of the window with the arrows
facing each other. This way the mag-
net wiII make a “clean break” from the
switch when the window is opened. If
you want to mount them on the side of
the window (so that the magnet “slides
past” the switch) you should offset
them slightly so that the arrows DO
NOT line up, as shown in the diagram
to the right.
To protect more than one door or
window fkom a single sensor
Use N.C. (Normally Closed) type
magnetic switches and Ioop them in
series from one door or window to the
next (using any suitable wire). Then
connect both ends of the loop to the
sensor. See below.
Note: N.C. means Normally Closed.
This type of magnetic switch is sup-
plied with the sensors. These switches
are normally closed when the door or
window is closed, and open when the
magnet is moved away. This type of
magnetic switch is used so that if the
wire between the magnetic switch and
the Door/Window Sensor is cut, the
alarm trips. If you want to connect
more than one magnetic switch to a
sensor you will need to connect them
in series (not in parallel).
You can use Normally Open (N.O.)
magnetic switches if you want to con-
nect them in parallel but the alarm will
not trip if someone cuts the wire be-
tween the switch and the sensor.
