Installation of the LT445 control circuit board and the LT420 basic transponder
Mounting the LT420 basic transponder
1. The LT420 basic transponder is mounted in the same way as the LT400 car transponder. Ensure that
the transponder is mounted at a location where it can detect the arriving vehicle. Avoid mounting it
behind bushes or other obstacles.
2. Mount the LT420 at the same height or as near to it as possible as the LT400 on your vehicle. This
is especially important to guarantee the communication between the vehicle transponder and basic
transponder at a short distance.
3. Make sure the cable is long enough to reach the location where the control circuit board is mounted.
4. We recommend using 2 x 25 mm drill holes site by site.
5. Take care not to push too hard on the front lens of the LT420 when
fi
xing in position - Do not use
sharp instruments.
6. Ensure that the cable cannot be pinched. Especially when the system is used to open and close gates.
7. Connect the plug of the LT420 to the control circuit board.
8. Connect power to the home controller circuit board using the power supply provided or utilise power
from the gate controller or garage door controller if 20-27 V AC or DC.
Two LT420 transponders can be connected to the control circuit board (depending on the actual
circumstances).
Connecting the LT445 control circuit board to the gate or garage door
The control circuit board is connected to the garage door or gate di
ff
erently depending on the brand
and type of door or gate. Refer to the garage or gate system dealer for instructions for the connection
of the system to your gate or door.
The switching o
ff
can be delayed by 5 to 120 seconds when the potentiometer is connected to the
control circuit board. Turn the potentiometer in the direction of the arrow to increase the delay.
The control circuit board should be placed in a separate waterproof cabinet if it cannot be placed inside
the gate or garage door switch box.
