Wiring Diagram – Sample wiring and applications
Important Notes
- Make sure that the door and frame is wide and deep enough to install the shear lock. Make sure the central lines on the door frame and door leaf align. Install the magnet into the door frame before installing the armature assembly into the door leaf.
- Before installation, make sure the door always returns to the dead center after it is opened, especially with double-action doors. Use door hinges if necessary.
Armature Plate Set Screws
Tighten the set screws with the Allen wrench provided once the armature plate has been adjusted for optimum door gap. This will firmly secure the armature plate and prevent it from becoming loose over time
Mortise Mount
- Make sure the gap between the door top rail and frame header is 2 mm.
- Mark the central lines on the door and frame where the magnet and armature assembly will be installed.
- Attach the templates to the door and frame.
- Cut and drill holes where the templates indicate. Connect the wires. Install the shear lock and armature assembly towards the leading edge of the door.
- Connect to the power and check the unit.
A. For proper operation, the armature assembly must be close and parallel to
the shear lock, without interfering with opening and closing of the door.
Keep a distance of 2 mm between the armature assembly and the magnet.
B. If the magnet attracts the armature assembly when the door is not in
position, please adjust the door operator and floor hinges.
For Vertical Installation
Connecting Diagram
Caution:
Make sure that the”+”and “-”wires are connected correctly. Please ensure the
voltage selection (see Jumper Setting below) is correct for the power supply
that is used. Failure to observe polarity and the correct voltage will result
in damage to the product and is not covered by the warranty.
Power supply:
The product must be powered from a UL-listed regulated, power-limited, power
supply.
If power switch is not wired between DC source voltage(+) and magnet, it will
take a longer time to de-energize the magnet simulating residual magnetism.
The minimum permissible wire size to be used shall not be less than 22 AWG.
