Electromagnetic locks have become the preferred door release mechanism for many
end users and installers. The magnetic locks have no moving parts, making them maintenance free. They are not affected
by back pressure (or backload) in the event of a real emergency.
They are Fail Safe - the door able to be opened when the power is disconnected.
The magnetic lock should always be installed on the secure side of the door. Power can
be disconnected intentionally or automatically by the buildings fire panel, a smoke alarm or any other type of
alarm.
The magnetic locks are available in a variety of sizes and have several optional features to enhance their operation.
The size of the magnet is indicative of its holding force. In the ROFU line are magnets with holding forces from
275 to 2900 pounds. Optional features include Door Status Sensor, Delayed re-locking, Delayed
Egress or Anti-Tamper sensor. Please see the following pages for more detail.
The locks can be used in most any application - from basic access control to high security. They operate when
DC electric
current is applied to them and stop working when the power is turned off. As a result, any type of access control
system that can open or close a relay, can interface with an electromagnetic lock.
