SHALOM® ENTERPRISES
An ISO 9001:2000 certified company
- Inspect the frame header to determine if an angle bracket or filler plate is required
- Fold template as indicated by dotted line. For single doors, locate template against the door and header on the lock jamb side of the frame
- Mark and drill holes as indicated in template. For armature plate hole Preparation,
- Mount armature to door. To determine proper hardware (provided)
- Install mounting plate to header with the interlock detail away from the door side of the stop, with #10 Flt Hd. Screws provided. From Sexnut side of door, drill exactly 1/2" hole thru one metal thickness only. From Armature side of door, drill 5/8" hole to insert reinforcement tube. Press in sexnut and reinforcement tube all the way and mount armature to door using hardware provided

Problem
|
Cause
|
Solution
|
1.
|
EM locks releases slowly. (residual magnetism)
|
Control switch wired on AC side of power source
|
Control switch must be wired on DC side of power supply
|
When an AC transformer and rectifier are used, the control switch must be wired between the rectifier and the EM lock.
|
|||
Field installed diode in parallel with power input
|
Remove diode.
|
||
2.
|
Poor holding force.
|
Armature installed rigidly
|
Armature must pivot loosely from its center mounting point to permit full armature contact
|
Check for proper voltage at the EM lock input. If low, determine if the correct wire gauge is being used to prevent excessive voltage drop.
|
|||
Low voltage
|
Check power supply load capacity. It must meet or exceed the combined current rating of all locks on the circuit.
|
||
A.C Voltage Input(EM Lock Will Make a humming noise)
|
EM locks require DC input voltage. When AC voltage from a transformer is used,a full wave bridge rectifier must be installed to convert the AC voltage to DC voltage.
|
||
3.
|
No holding force. Door does not lock.
|
No power
|
Check the voltage at the EM lock. If the voltage is low or zero, double check all wire connections and the power supply.
|
Input Polarity Reversed
|
Check voltage polarity. Terminal (-) is: Negative. Terminal (+) is: Positive
|
||
Open circuit in EM lock Coil
|
Check coil continuity with OHM meter. If reading is high or open, replace the magnet coil.
|
||
Magnet Coil Short
|
Coil shorts or incorrect wiring will blow fuses. Measure the coil for correct resistance
|
Installation Instructions:
Trouble Shooting:
- While Installation, screws should be fixed tightly.
- Because it is weight it may fall down while opening the door.
- Electro magnetic lock is weather proof, tamper proof and its operating voltage is 12v D.C which is low.
- Because its works in Low D.C voltage there is no possibility for Electric shock ,sparks or short circuit.
- There will not be any risk by using.
Risk analysis
- Holding the magnet housing at each end, engage the entire length of the interlock detail, by pushing towards the door. (If necessary, tap with a soft hammer to ensure proper alignment and engagement). Caution: The lock body must be held in place until secured with mounting screws. Screws provided inside the housing at each end. Tighten the screws and check alignment.
- Test operation. When all is operating properly, tighten all screws. Install anti-tamper plugs over socket head screw using a soft hammer to avoid damage to the housing. Electromagnet and armature should be handled carefully. Any damage to the surface such as paint, burrs, dirt and rust may hinder bonding of surface and reduce holding power.
