Terminal 15 & 16 : Alarm memory relay contacts
These contacts operate at the same time as the alarm relay contact. However, the contacts remain activated until the
power is turned off or the alarm key switch is turned "off-on-off" (same as the Alarm Memory LED). It can be used to
provide an external indication of the fact that the alarm has been triggered (alarm memory). Again, the max. current for the
contact is 3 Amps. Power is connected in the same way as with terminals 13 and 14.

Terminal 17 & 18 : Power input
The polarity of these terminals is irrelevant if you have a 16V AC panel. Simply connect the two wires from the plug pack to
these terminals. If you have a 12V DC panel, you should be careful to connect the power supply using the correct polarity :
terminal 17 is positive (+), terminal 18 is negative (-)*.
IMPORTANT : The standard Velleman version of this product is supplied with a 13.8VDC power supply !!!
If you do not know which type of panel you have, you should check the area behind the terminals under the main circuit
board. If you have a 16V AC panel, you will find a small auxiliary circuit board of approx. 50 x 25mm in this area.
* Note : the DC input voltage should be 13.8V (or 14V) to ensure correct charging of the battery.
