Gate Triggering
The gatestation has 2 separate triggers used to opening/closing gates. Both gates can be triggered from
the handset. During a call the door lock button is pressed once to activate and under standby the buttons
must be pressed in for 3 seconds in order to trigger.
The contacts are located at the back of the intercom. Lock A is a 1amp pulse output of the 12V supply.
This is used to trigger strike locks such as used for pedestrian gates. If Lock A is used to trigger a
standard gate motor it is essential to use the supplied relay board as shown in the figure below.
Lock B is a 300mA dry contact which is normally open. Once the Lock B trigger is activated the pins of
Lock B will connect and make a short circuit and close. This connection can be connected directly to the
gate controller board of a gate motor. It is advisable to also use a relay board for trigger B to isolate the
gatestation from power surges etc. The connection is different as the power wires to the relay should be
connected in series with the trigger B contacts.
A standard receiver can also be connected on the gate controller board in parallel with the gatestation if
remotes are required.
Connection to a gate motor using DC power
There is
no required polarity
for the DC connections
although the relay board has polarity. If pin 1 is 0v and pin2
12v, so pin A will be 0V and pin C 12v when triggered.
Connect the relay board as shown with Pin A to the Neg (0V)
contact and Pin C to the Pos (12V) contact. The relay has a
LED light which will light-up when triggered. Connect the
Com and N.O. pins of the relay board to the Com and Trg pins
on the gate controller board.
