Pre-Installation Instructions 

1.

   This product must be installed according to all applicable 

building and life safety codes. 

2.

   Due to the variety of mounting configurations available with 

this product, a survey and assessment of the physical area 
in which the product will be installed must be performed. 

3.

   The door frame must be inspected and deemed structurally 

sound prior to installation of the electromagnetic lock. The 
structural integrity of the mounting surfaces must be strong 
enough to meet or exceed the holding force of the product. 

4.

   The product must be protected from potential damage due 

to intruders or tampering. 

5.

   The product should be installed in a location that will not 

hinder or create a potential safety hazard to authorized 
personnel accessing the protected area. 

6.

   Because electromagnetic locks are used in a variety of 

applications and different door frame configurations, an 
experienced installer with knowledge of this product must 
make a determination of the optimal mounting method for 
this specific application. 

7. 

  The components, hardware, installation instructions and 

mounting template included with this product are intended 
for use on outswinging doors. 

8.

    Do not install this product on the exterior of buildings. 

9.

  Do not use as a doorstop. This will void warranty.

 

   

10.

   Installation of this product should be done by an 

experienced installer with knowledge of this product. 

NOTE: 

It is highly recommended that thread locking compound 

be applied to all screws during installation to reduce chance of 
screws loosening over extended time.

NOTE: 

New Installation:

Retrofit Installation:

           During the installation of the armature plate to the door it 
is essential that the armature plate remains movable. The 
armature plate must be allowed to pivot on the center-mounting 
bolt to allow proper alignment with the magnet surface. If the plate 
is not aligned with the magnet surface, the lock may lose holding 
force or not lock at all. 

The head of the armature mounting bolt ships with a rubber washer 
affixed to it. This washer should project slightly beyond the surface 
of the armature plate. This is to allow the washer to expand when 
power is removed and break the air vacuum between the plate and 
magnet surface. If this washer is removed or trimmed, the lock will 
appear to have some holding force even when power is removed. 

PLEASE DELIVER ALL INSTALLATION INSTRUCTIONS TO  

THE END-USER UPON COMPLETION OF THE INSTALLATION.

INSTALLATION INSTRUCTIONS

Mounting Instructions

Installation of this product should be done by an experienced installer 
with knowledge of this product.

Step 1a) 

Read Pre-Installation Instructions.

Step 1b) 

Prepare Door & Frame (for new installs)

 

Place against closed door and header  with allowance 

 

for Allen key clearance from the edge (1 -1/4" ).

 

Drill the middle hole in the door and 2 holes in the

 

header as indicated. Center mark the two holes to

 mount 

armature 

holder.

 

NOTE: Different hole sizes required for the different materials.

 

Do not use as a doorstop. This will void warranty.

Step 1c) 

Mount Armature Plate

 

Position bolt with rubber head through the armature plate.

 

Carefully apply thread locking compound to exposed thread.

 

Secure armature plate to door and armature holder by  

 threading 

into 

sexnut.

 

Step 1d) 

Mount Electromagnetic Lock

Remove blocking screws from front of lock.  
Remove electromagnetic lock from mounting bracket by  
loosening captive screws and sliding off keyholes. 

Attach bracket to header with the 2 panhead machine screws  
or the self drilling screws provided through the slots. 
NOTE: Do not over tighten these screws as the bracket may 
need adjustment. 
Slide electromagnetic lock onto mounting bracket keyholes. 
Engage 1 captive screw at each end through bottom to fix lock 
position on bracket. 
Adjust alignment to ensure full contact of magnet with  
armature plate. 
Carefully remove electromagnetic lock without shifting 
mounting bracket. 
Secure mounting bracket in position with either 9 TEK™ 
screws or 4 flat counter sunk machine screws. 
Drill ¾ (19mm) wire access hole using mounting bracket as 
a guide. Tip the electromagnetic lock to expose the 4 captive 
mounting screws. Carefully apply thread locking compound to
exposed threads. Slide the electromagnetic lock onto 
mounting bracket keyholes. 
Secure with 4 captive mounting screws.

Attach bracket to header with 9 TEK (tm)  screws or 4 flat 
counter sunk machine screws utilizing holes from previous 
installation. 
Additional TEK screws may be used for added strength.
