9.2.4 Wiring on the mainboard
Caution!
Disconnect the device from the power before performing wiring work or
making changes to the wiring.
Operating voltage (+12V/0V)
Connect the “12 V” terminal to the positive terminal and the “0 V” terminal to
the negative terminal of the power supply.
As a voltage source,

use a voltage output of your alarm control panel
or

an external power supply unit (if the device is intended to be
operated as a standalone device).
Pay attention in both cases to the amount of voltage and the current rating of
the voltage source.
Caution!
The device requires a supply voltage of at least 10.5 V and at most 24 V.
The voltage source must be capable of carrying at least 200 mA.
Inputs A
–H (A-TRIG to H-TRIG)
Connect the inputs A
–H with relay outputs of your alarm control panel, for
example. The possible variations are shown below.
If you are using transistor outputs, run the wiring accordingly.
All inputs must be triggered with the same polarity. The polarity settings are
adjusted under “System Options
 Trigger Polarity”.
