Electrified lock choices are limited when installing electronic access control on a narrow stile aluminum glass storefront door equipped with a pivoting deadbolt. As far as I am aware, no electric strikes will operate a standard aluminum storefront door lock with a 1-3/8” throw pivoting bolt. The keeper in most electric strikes is designed to accommodate up to a one-inch throw bolt.

Therefore, electrification options are narrowed down to the following four options:
Deadlatch and electric strike
Electrified deadlatch
Electronic deadlatch
Electromagnetic lock
The deadlatch options require either retrofitting the pivoting deadbolt or adding the second lock to the door. This can be difficult depending upon the location of the original pivoting deadbolt lock. According to the NFPA 101 Life Safety Codes and building codes specifications, securing a swinging door is normally accomplished by a deadlatch or deadbolt located between 34” and 42” above the finished floor. The 2010 ADA Standards for Accessible Design states hardware required for accessible door passage shall be mounted no higher than 48” above finished floor.

The choice of the electrification method depends upon the reason for electrification. Reasons can include daytime operation, security, primary/secondary locking mechanism, cost, etc.
When installing an electromagnetic lock onto aluminum glass door, the standard position is along the header. In this configuration, when the door is secured electronically, there is no locking mechanism activated along the swing side of the door.

A new solution to electrification of the storefront door is the Dortronics ML-1100 Series Mortise Lock & Pull. The lock mechanism is an electromagnet installed into the swing side aluminum jamb. The concealed armature is mounted into the handle, which is installed onto the pull side of the flush mount doors’ stile. This configuration allows the magnetic force holding the armature to be at or near the vertical centerline of the aluminum glass door, providing evenly spaced holding force and limiting the ability to rack the door.
