Installation Instructions

Lock Assembly
The 8310 and 8320 Electromagnetic Locks come with screws
installed in the housing. These screws, when in place, inhibit the
insertion of an Allen wrench into the mounting screw openings on
the underside of the lock. These screws will need to be removed
prior to installing the lock so as to allow the mounting plate to be
removed from the top of the lock. Fig 3 illustrates the location of
these screws. One screw acts solely to inhibit tampering while the
screw on the other end discourages tampering while holding the
cavity cover in place.
Lock Options
The 8310, 8320, 8330, and 8340 locks can each be equipped with
remote indication features that operate as follows. See Fig.1 for
wiring diagram. Each of these features will provide indication as
to the lock status. Status is indicated locally via an LED mounted
on the bottom of the lock housing. Remote notification can also
be achieved by connecting a monitoring device to the SPDT relay
included on the lock circuit board.
SCS (Security Condition Sensor)
This feature can detect the quality of the locking bond between the
surface of the magnet and the armature plate. The sensitivity of
this feature is such that a foreign object with a thickness of .007”
(.18mm) is sufficient to allow the sensor to detect a problem.
Due to the sensitivity of this feature and the necessity to maintain
a reliable locking bond, these surfaces must be kept free of
contaminating materials. Both the lock surface and the armature
plate must be cleaned periodically with a non-abrasive cleanser.
Alignment of armature plate and magnet is required to ensure
proper function of sensor.
Low Voltage Detection
Each SCS circuit board also includes a low voltage detection
circuit when shipped from the factory. This feature will cause the
alarm relay and status LED to activate should the lock input
voltage drop below 10.3VDC if wired for 12VDC or 20.5VDC if
wired for 24VDC. That signals a monitored system or guard
station that the holding force of the lock may have been
compromised.
DSS (Door Status Sensor)
The DSS option monitors the position of the door upon which the
lock is installed. A SPDT reed switch mounted within the lock
cavity eliminates the need for extra sensors to be installed on the
door for notification of security or access control systems. The
DSS option comes with a magnet pre-installed into the lock
armature plate for signaling the reed switch in the housing when
the door is closed. Care should be taken during the final testing of
the lock to ensure that the DSS option is operating in the desired
manner.
Inspection and Maintenance
This product and all related accessories or parts must be
inspected and maintained on a quarterly basis. Contacting
surfaces of the electromagnetic lock and armature plate must be
kept free of contaminating materials. Surfaces must be cleaned
periodically with a non-abrasive cleaner.
All mounting fasteners must be inspected on a quarterly basis.
When properly installed, the ends of the armature plate allow a
slight movement but the plate will feel secure when grasped at the
bolt. There should be no movement to the mounting bracket or
housing of the electromagnetic lock.
For added safety, thread locking compound has been provided for
the armature plate bolt and the four captive electromagnetic lock
mounting screws.
WARNING: Improper installation, maintenance, inspection or
usage of the product or any related accessories or parts may cause
the electromagnetic lock, armature plate and associated hardware
to disengage and fall, causing serious bodily injury and property
damage.
PLEASE DELIVER ALL INSTALLATION INSTRUCTIONS TO
THE END-USER UPON COMPLETION OF THE INSTALLATION.
