Connection to a gate motor using AC power
A relay board is needed to trigger the gate motor as the gate motor trigger activates from one pulse
not an AC pulse, which is used by an electric door lock (see above). The relay board is an optional
accessory available from Zartek.
Part number for the relay board is GE-247.
•
Connect the red leads from the transformer to 220V
AC (mains).
•
Connect the white leads from the transformer to pins
1
and
2
on the intercom door station.
•
Connect wires from pins
5
and
7
at the back of the
door station to the
NEG AC
and
POS AC
pins on the
relay board. The polarity is not important as AC power
is being used.
•
Connect a lead from the
COM
pin on the
relay
board
to the
COM pin
on the gate motor controller board.
•
Connect a lead from the
N/O pin
on the
relay
board
to the
trigger (TRG)
pin on the gate motor controller
board.
Connection to a gate motor using DC power
There is
no required polarity
for the DC connections to operate the intercom function although if
gate opening is also needed, a relay board (GE-247) which does have a specific DC polarity requirement
will interface to the gate controller. Please see the diagrams below for the 2 options to connect using
DC power.
Option A 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
DC supply
(0 and 12V from the gate
motor controller circuit board) to the correct pins at the
back of the caller unit.
The 2 pins marked 8-12V AC
can be used for 12V DC as well.
