on the handset is pressed, the two terminals will be momentarily open circuited for a few seconds.
Normally opened (pins 5 (com) & 7)
These two terminals are normally open circuited and whenever the door lock opening button 11

Connecting the caller unit to a strike lock gate using AC power
An AC transformer (available from the supplier) is needed to step the voltage down to power the
caller unit. The Red leads are wired to the mains supply (220VAC) and the white leads to the power
slots at the back of the caller unit. There is no required polarity for the AC connections.
Procedure:
1) Insert 4 AA batteries (not included) into the battery slots. The LED indicator 2 should illuminate
and then turn off after about one second. If the light remains on or does not come on, reinsert
the batteries and ensure that there is not another supply connected.
2) Test the caller unit by pressing any of the channel buttons to ensure that the intercom is working.
Wait about 20 seconds for the ring to time-out or cancel the call when the handset rings.
3) Now connect the low voltage AC supply (2 white leads) to the correct pins at the back of the
caller unit.
4) To test the AC supply, remove one of the AA batteries and press any of the channel buttons. If
the caller unit rings then the power connections are working but if no ring is sounded go back
to stage 1. above and repeat the process of connecting the AC power.
5) Connect the leads from the electric door lock to the pins at the back of the door station, one to
the com pin and one to the normally-open/closed pin (last 2 pins in the block).
