Security Door Controls

Designed and patented by SDC, Spacesaver right angle bolt locks represent a fundamental innovation in electric locking technology for access control applications. Spacesaver bolts project at right angles to the lock mechanism, allowing installation of Spacesaver locks, by means of a simple mortise cutout, in virtually any standard frame, or in most door lock stiles. With the entire lock concealed, aesthetic acceptability is complete, security is greater and installation in old or new construction is fast, easy and economical. FS23M locks are equipped with nylon bolts with hardened magnet cores, specification grade solenoids and automatic relock ball switches. Bolts rotate freely, making attempts to tamper or cut extremely difficult. Specification grade solenoids facilitate superior overall performance in both force and longevity, when compared to commercial grade solenoids. Automatic relock ball switches keep the bolt retracted while the door is open. The door depresses the ball switch on closure, causing the bolt to project automatically, locking the door. Additionally, ball switches are field adjustable to compensate for wide door gap and bidirectional to permit use on swinging and sliding doors. Dual failsafe bolt locks are available only from SDC. Conventional failsafe locking bolts rely solely on a spring to retract the bolt while the FS23M bolt will unlock with or without the assistance of the spring. This is the only electric bolt lock listed by the California state fire marshal for locking of perimeter entrance and emergency exit doors after hours. Large repelling magnets are located within the bolt and strike. Should the spring fail, repelling magnets eject the bolt from the strike, unlocking the door.

Models:

• FS23MI: Right angle bolt lock, dual failsafe

Applications:

• Dual Failsafe Operation: SDC designed and patented FS23M bolt locks are locked when energized. Recommended for safety applications, the door unlocks automatically when power is interrupted by the access control, power failure or a signal from the fire life safety system. Large repelling magnets are located within the bolt and strike. When power is interrupted the bolt is retracted and held back by a spring. Should the spring fail, repelling magnets eject the bolt from the strike, unlocking the door. The bolt is made of a lightweight and extremely resilient nylon material. While lack of weight enables the magnet to eject the bolt, an inherent feature is powerful and smooth operation. The longevity of this lock is unsurpassed compared to electromechanical locks with steel bolts and abrasive metal to metal interaction. Additionally, the nylon bolt boosts 2,500 lbs of strength and is resistant to metal cutting saws with its hardened magnet core. While designed for perimeter applications the performance characteristics of the FS23M make it the first choice for all interior or exterior openings where the use of an electric bolt lock is applicable.
