LK-M03
MAGLOCK 300 LBS
Installation Manual

1. Introduction

The LKM03 is a surface mounted magnetic lock series with 300 lbs
holding force. LKM03 has dual voltage (12 or 24 VDC) and low current
consumption with anodized aluminum housing. LKM03 has a built-in
voltage spike suppressor and no residual magnetism.
Different types of bracket and housing are available to fit various
mounting conditions.
LKM03 is compatible with EN55011:1998: Class B, EN60601-1-2:2002,
EN61000-4-2:1995, EN61000-4-3:2002 & UL-S5351.

3. Mounting

Before attempting to install magnetic lock:
 Handle the equipment with care. Damaging the mating surfaces of
the magnet or armature plate may reduce locking efficiency.
 The magnet mounts rigidly to the door frame. The armature plate
mounts to the door with hardware. Kit provided that allows it to
pivot about its center to compensate for door wear and
misalignment.
 Template use must take place with the door in its normally closed
position.
 Before installing, please add the thread locker to all screws. Firmly
tighten the screws to avoid fastening loosen.

Mortise Mounting

Fix the armature plate not too tightly and make the rubber washer
more flexible to make the armature plate automatically adjust its
proper position with the magnet.
Typical mortise mountings are shown in the following figures.
