The EM3500 is a 280kg single magnetic lock and EM3500D is a double magnetic lock, both unmonitored. The EM3500M is a 280kg single magnetic
lock and EM3500DM is a double magnetic lock, both monitored. The Lock Status Switch (LSS) indicates if the lock is powered and the magnetic bond is
active using a Hall Eect crystal. The output is an on board relay, and the dual back-light indicator.
The Door Status Sensor (DSS) is a passive reed switch for monitoring of door status, used in access control for door status.
Reed does not rely on power to operate.
The monitored EM3500M/DM’s are supplied with an anti-tamper plate to assist in mounting the armature plate.
The (+) lead of the power source is connected to terminal 1 of the terminal block and the (-) lead is connected to terminal 2 (-). The operating switch must
be installed between the power source and the magnetic lock to reduce operating time of the magnetic lock to a minimum. The electromagnetic lock
requires a filtered and regulated DC power source.
RED jumper (default setting) is 24 volts, and BLUE is 12 volts.
Please note: These voltage shunts must be set correctly before 12 VDC or 24 VDC power is supplied to the Electromagnetic Lock to prevent damage to
the unit.

INSTALLATION MANUAL
INSTALLATION TIPS:
The Armature Plate must remain flexible - the armature plate must be remained movable to allow surface alignment with the magnet face. The magnetic
lock will lose holding force without this floating alignment.
Do not trim the rubber washer mounted on the head of the armature center bolt. Trimming rubber washers will adversely aect the release of the arma-
ture plate from the magnetic lock.
IMPORTANT SAFETY REQUIREMENTS
Apply thread-locker glue (e.g. Loctite) to the thread of the Armature-Plate-Fixing Screw (Allen-Screw) to prevent from becoming loose.
Locks should be inspected at regular intervals to ascertain the safety functionality.
The supplied Allen screws cater for maximum door thickness of 45mm.
Contacting surfaces of the electromagnet and armature plate must be kept free of contaminating materials. Surfaces should be cleaned periodically with
a non-abrasive cleaner. Do not spray the electromagnet or armature plate surface with any lacquer chemical, this will create problems with the release
of the magnetic lock and armature plates.
PROBLEM POSSIBLE CAUSE SOLUTION
DOOR WILL NOT LOCK NO DC VOLTAGE TO LOCK. LOOSE WIRE ON
TERMINAL STRIP
CHECK POWER SUPPLY AND WIRING TO
MAGNETIC LOCK
REDUCED HOLDING FORCE BAD PHYSICAL CONTACT BETWEEN ARMATURE PLATE AND FACE OF
MAGNET. INCORRECT VOLTAGE JUMPER SETTING
ENSURE MATING SURFACES ARE CLEAN AND IN PROPER ALIGNMENT AND THE
ARMATURE PLATE FLOATS FREELY.
CHECK MAGNETIC LOCK FOR LOW VOLTAGE OR WRONG VOLTAGE SETTING
DELAY IN DOOR RELEASE CIRCUIT SWITCH IS NOT BETWEEN MAGNETIC LOCK AND POWER
SOURCE. SECONDARY DIODE INSTALLED ACROSS MAGNETIC LOCK
RE-WIRE CIRCUIT SWITCH BETWEEN MAGNETIC LOCK AND POWER SOURCE.
REMOVE ANY INSTALLED DIODE. VOLTAGE SPIKE PROTECTION IS ON THE PCB.
LED STATUS IS INCORRECT
MISALIGNMENT OF ARMATURE PLATE.
REED SWITCH LOCATED IN WRONG POSITION IN MAGNETIC BLOCK.
INCORRECT VOLTAGE SETTING
CHECK ALIGNMENT OF ARMATURE PLATE.
ADJUST JUMPER TO CORRECT VOLTAGE.

TYPICAL FIXING OF MAGNETIC LOCK ON IN-SWINGING DOOR
ADJUSTABLE L BRACKET ADJUSTABLE L ARRANGEMENT
Armature plates must be installed with the components shown above.
These components are provided with each electromagnetic lock.
Adjustable L Bracket is for flush
transom or narrow header.
L Bracket is for narrow header.
Armature plates must be fixed as shown above. Do not over tighten the
fixing screw. The armature must be allowed to ‘float’ on the rubber washer.
(TO AVOID MALFUNCTION OF THE LOCK DO NOT USE PARTS OTHER THAN THOSE PROVIDED ABOVE)
