When the exit must be controlled, it is necessary to provide a fail-safe device, such as an electromagnetic lock, that will keep the door locked not only on the entry side but also on the exit side of the door.

In the past, the installation of electromagnetic locks may have been considered to be less costly than the installation of door strikes. As a result, the market for electromagnetic locks has grown exponentially over the past few years. Unfortunately, a great number of electromagnetic lock installations were not done according to regulations and in some instances were actually jeopardizing the safety of occupants. The proliferation of electromagnetic lock installations has caused great concern amongts safety regulators and, now, stringent local regulations and site inspections are common. This has caused a substantial increase in cost of using electromagnetic locks. Because of these extra costs, the use of electromagnetic locks may be more appropriate in situations where they are the only alternative, such as locking a controlled exit door.

Regulations
National and local building codes and fire ordinances usually regulate the use of locking devices. One must remember that these are usually minimum requirements and that the local authorities may have the last word in interpretation and exceptions. Always check with local authorities before installing any locks. Once installed, it can be quite expensive to replace the locks and repair doors and door frames.

Other locking devices
Mechanical devices (such as electric deadbolts) that prevent free exit are usually not permitted for use in access control applications. Check with local authorities

Security
O&C´s Mini EM Locks are fitted on the protected side of the door. Common methods of forced entry (such as splitting the door frame) will not defeat electromechanical locks.
Ideal for Safety Applications
Completely fail-safe. No moving parts to break down. Ideal for fire exit doors. Meets most countries´Building Codes for electrically controlled exit devices.
Dual Voltage
All O&C´s Mini EM Locks are prepared to operate at either 12V or 24V DC.
Silent Operation
All O&C´s Mini EM Locks are absolutely silent, whether activated or not.
Long Life
Total absence of moving parts and mechanical wear makes maintenance unnecessary.
Traffic Density
All O&C´s Mini EM Locks resist wear from high traffic.
Simple Fitting
Magnet (mounted on the frame) does not require milling or mortising in most applications. Can be screwed to the vertical or horizontal part of the door frame. Armature (mounted on door) requires only three holes to be drilled. Very simple.
No Residual Magnetism (NF S 61-937)
Numerous tests prove immediate free access as the current is cut off
