1091AIV is locked when energized. Recommended for safety
applications, it is intended that the door unlock automatically
when power is interrupted by the access control, power failure
or signal from a fire life safety system.

The Spacesaver®, first designed and patented by SDC, is a
fundamental innovation in electric locking technology for
access control applications.

Finish: V - Clear Anodized Aluminum
Bolt Throw: 0.75”

The stainless steel bolt projects at right angles to the lock
mechanism, allowing installation of Spacesaver® locks,
by means of a simple cutout, in virtually any standard 1.75"
frame, or in most door lock stiles.
With the entire lock concealed, esthetic acceptability is
complete, security is greater and installation in old or
new construction is fast, easy and economical.

Stainless Steel Bolt
Greater security is provided by the 0.625” diameter
solid stainless steel bolt. The bolt rotates freely, making
attempts to tamper or cut extremely difficult.

Specification Grade Solenoid
All Spacesaver® lock solenoids are manufactured by SDC
to precision specifications. SDC solenoids are capable of
superior overall performance in both force and longevity,
providing years of service compared to commercial grade
solenoids.

Code Compliant
Classified in accordance with Uniform Building Code
standard 7-2, “Fire Test for Door Assemblies”

Field Adjustable Auto-“Relock Switch
The automatic relock switch keeps the bolt retracted while
the door is open. The door depresses the ball switch
assembly on closure, causing the bolt to project automatically,
locking the door. In addition, the ball switch assembly is
bidirectional, permitting the locks to be used on swinging and
sliding doors.
