*NOTE
: Connect switching devices like
push-to-exit switches between the power
source and the positive terminal on the
lock. Connecting switching devices to the
negative terminal may cause a delay in
unlocking.
Check to make sure the wires are securely tightened to the terminal block.
Check that the power supply is connected and operating.
Make sure the rubber washer is installed and free from damage.
Door locks, but can easily be forced open
Make sure the electromagnet and armature plate are properly aligned.
Make sure the contact surfaces of the electromagnet and armature
plate are clean and free from rust.
Check the power leads with a meter, and make sure 12VDC or 24VDC is
present.
Make sure the rubber washer is installed and free from damage.
Door does not lock
Troubleshooting:
Position a jumper over

Power Supply
SECO-LARM
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.
Maintenance
Wipe the surface of magnet lock with anti-rust oil regularly.
