template provided.
2. Attach the armature plate to the door with the hardware
provided as per Figure 2.3
3. With the door closed, mark the door frame at the edge of
the armature in order to properly align the electromagnet
to the armature.
4. Attach the mounting plate to the door frame using the
self-tapping screws provided.
Align the mounting plate with the mark from Step 3.
5. Insert the wires through the hole in the mounting plate
and into the electromagnet unit. Attach the electromagnet
unit to the mounting plate with the Allen head fixing screw.

prevent rust.
4. Trouble Shooting
1. Sensor not functioning:
- Improper attachment of electromagnet and
armature plate
- Modification of the PCB
2. Door not locked:
- Incorrect wiring or no power from power supply
3. Reduced holding force:
- Poor contact of electromagnet and armature.
- Be sure armature is loose enough that it can fully
contact electromagnet along the entire length
- Mating surface is dusty or damaged.
- Improper input voltage or wire size.
