Page 2: Product Overview
Product Overview EM Lock The electromagnetic lock consists of an electro magnet and a steel plate which are mounted onto the door frame and to the top of the door respectively. The door will be strongly bonded when the magnet is energized, by the means of electric supply, holding the steel plate. - Page 3 Installation Guide The Emlock is mounted to the underside of the header, on the stop side of the door. A TJ mounting kit (optional) can be used when mounting on the hinge side of the door. (Fig. 1D) The armature is mounted to the door. A hardware kit is provided to compensate for misalignment and wear of the door, by allowing the armature to pivot on its center point.

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 SHOULD THE SURFACE PLATING BE DAMAGED: Do not touch the lock face with your hands...

Electrical Instruction: 1. Use jacketed cable for all wire runs. Refer to the SDC wire gauge chart for proper lock power wire size (18 AWG gauge minimum). 2. Use only shielded cable for all signal wires. 22 AWG gauge (minimum) may be used for signal wires up to 1,000 feet. 3. -

Do not install a diode in parallel with any magnetic lock. A diode will cause a delay when releasing the door and residual magnetism to occur. Although Essl recommends the use of a DC power supply, a transformer with an adjacent mounted full wave bridge rectifier may be used. -
Page 8: Operation
The principle behind an electromagnetic lock is the use of electromagnetism to lock a door when energized. The holding force should be collinear with the load, and the lock and armature plate should be face-to-face to achieve optimal operation. Operation The magnetic lock relies upon some of the basic concepts of electromagnetism. -

- Sturdy: Magnetic locks may also suffer less damage from multiple blows than do conventional locks. If a magnetic lock is forced open with a crowbar, it will often do little or no damage to the door or lock. Disadvantages - Requires continuous power: To remain locked, the magnetic lock requires a constant power source. -

Holding force A magnetic lock has a metal plate surrounded by a coil of wire that can be magnetized. The number of coils determines the holding force which characterizes the lock: - Micro Size: 300 lbs (1,300 N) holding force. - Mini Size: 600 lbs (2,700 N) holding force The standard size electromagnetic lock is used as a gate lock. - Page 11 #24,Shambavi Building, 23rd Main,Marenahalli, JP Nagar 2nd Phase, Bangalore - 560078 Phone: 91-8026090500 | Email : sales@esslindia.com www.esslsecurity.com...
