Electric Strikes

It is recommended to use a fail secure, continuous duty electric strike that must be powered to unlock the door. The fail secure door strike will keep the door secure in case of power interruption. Order strikes as: 1) fail-secure (locked when you remove power), 2) 24VDC, 3) continuous operation, and 4) low current. These specifications will usually correspond to the requirements of access control. Some strikes can also be ordered with a self-contained micro switch indicating whether or not the pen is actually held by the strike. This contact is usually wired in series with the door contact. On double doors, the door strike will be installed on the passive door which should be bolted down and a door cord or electric-conductive hinge will carry the power to the strike. It may not be possible to install door strikes on special doors such as full glass doors. The only alternative may be to install an electro-magnetic lock.
