Mechanical locks are manually operated (locked and unlocked) by key at the door. Electric locks are released from a remote control location, while manual operation is performed at the door by key.

Southern Steel locks can be classified as detention or institutional locks. Detention locks, consisting of mechanical and electric operated locks, are manually locked and unlocked by a paracentric-type key measuring 4 1/2" -long by 5/32" -thick. Each detention lock contains at least 5 brass tumblers with phosphor bronze springs. Cases and covers for Detention locks are typically constructed of iron or steel. To ensure maximum security for detention locks, master keying is not available.

Institutional locks are designed and installed for use where security requirements may be less stringent and where the appearance of a more conventional lock and key is desired. These locks consist of both manual key-operated locks and electric/manual operated locks. Most institutional locks are equipped with a mogul cylinder. This rugged 2 1/4" diameter cylinder is more than twice the size of a standard builder's hardware cylinder. Pin tumblers and tumbler-engaging balls are stainless steel to reduce friction and wear. (Mogul cylinders contain 5 tumblers.) Keys for mogul cylinders are 2 15/16" -long by 1/8" -thick. Master keying for institutional locks, although available, is not recommended.

In addition to the specific maintenance procedures outlined for each lock in this section, the following requirements must be met:

1. The success of any maintenance program is directly related to the ability and performance of operations personnel. During the period immediately following the introduction of new equipment or operating personnel, many reported malfunctions can be traced to improper operating procedures. It is therefore recommended that a training program be established to ensure that all personnel are thoroughly familiar with applicable operating procedures and preventive maintenance requirements. It should be emphasized that mechanisms should never be forced, and that all malfunctions must be reported to maintenance technicians immediately. In short, operating personnel playa major role in keeping equipment problems at a minimum.  

2. When installed, all locks are adjusted to provide a lasting and efficient operation. Before attempting any adjustments to the lock, inspect door and frame for maladjustment. The door and frame must be square, level, and plumb. There must be a 1/8" clearance between the lock side of the door and the frame. This is to ensure proper distance of strike to lock. Also, the door must have a 1/16" to 3132" free play {movement of door in and out) when closed and locked. Anything less may not allow free movement of lock bolt in strike. Lock bolt should freely engage/disengage strike when keyed.

IMPORTANT: NEVER FILE OR GRIND ON LOCK BOLT OR STRIKE. Adjust lock mounting or shim door {hinges) to obtain proper lock bolt and strike clearance.

3. Inspect lock and strike for foreign objects at least once a month. Remove any excess debris from lock strike or keeper.

4. Once a month check for loose screws or other mounting hardware. Securely tighten all loose nuts and screws.

5. Lubrication requirements for detention/institutional locks depends upon frequency of operation and environmental conditions. Generally, all locks should be inspected twice a year if the lock is used fifty {50) times or more per day. If the lock is used less than fifty {50) times a day, inspect and lubricate at least once a year. In addition, door hinges should be lubricated every six months to ensure smooth door movement.

If the equipment is operated in high ambient temperatures or extreme dusty environments, lubricate more frequently.

Basically, all moving parts in locks should be lightly sprayed with lubricant.

Do not excessively lubricate locking device.
