Pedestrian Keyswitch - Centsys D3 User Manual

Most automatic gate installations are fitted with an intercom which provides for
communication between the house and the gate.
The intercom handset is usually provided with a "Gate" or "Door Release"
pushbutton which, when pressed, sends a signal to the gate controller to open the
gate.
The sequence of operation of this pushbutton is identical to the radio transmitter
described under "Radio Transmitter".
Pedestrian keyswitch (optional)
The pedestrian keyswitch is fitted to the gate pillar. It's purpose is to open the gate a
limited amount for pedestrians.
The gate will open approximately one metre and then stop. After five seconds the
gate will automatically close.
The gate can be held open by keeping the key turned in the keyswitch. As soon as
the key is released back to its normal rest position, the gate will close after the five
second delay. (The opening distance and the time that the gate remains open can be
adjusted to suit. Default values are described above).
If a protection beam has been fitted (refer section "Protection Beams") and the beam
is broken while the gate is closing, the gate will stop. The gate will remain in that
position while the beam is broken and only close five seconds after the beam has
been cleared.
Fit the key into the keyswitch and
turn the key clockwise as though
starting a motor car.
Let key spring back to rest position
and remove key immediately.
To allow time for removal of the key,
there is a five second delay before the
gate begins to open. If the courtesy light
is connected to the control card it will
flash five times, indicating that the
signal has been accepted.
