Installation Applications
• When mounting the electromagnet, it may be necessary to use a "Z" and "L" bracket, an
"L" bracket, a "U" bracket, and/or plate spacers, depending on the location and the type of door
and frame.
• Use the diagram below to help decide whether or not an optional bracket will be necessary for
installation.
Installation Notes
1. Read this installation manual thoroughly. A clear understanding of the product and this manual
will make installation much easier.
2. The electromagnetic lock is designed for indoor use ONLY.
3. The most suitable mounting location for the electromagnetic lock may require the use of
additional SECO-LARM accessories such as Z-brackets, L-brackets, and/or spacer plates.
Please see the diagram on page 3 to decide if a particular application requires any mounting
accessories.
4. Do not run power wires and signal wires in the same conduit as this may cause interference.
5. Do not install a diode in parallel with the electromagnetic lock as this may cause a delay when
releasing the door as well as cause residual magnetism.
6. The best location to install the electromagnetic lock is on the inside of the door that is being
secured with the wiring concealed in the frame to prevent tampering with the unit.
7. The minimum permissible wire size to be used shall not be less than 22AWG.
