Electric Lock Options

Consumers interested in some of the most modern trends for locking mechanisms may wish to consider electric locking options. These options range in price and can provide consumers with a wide variety of advantages as well as security insurance.

Electromagnetic locks can be a good choice in lock systems depending on your needs. The lock itself is constructed of a steel plate that is attached to the door. This is then held against a strong magnet that is attached to the frame of the door. Electromagnetic logs are fail-safe, meaning they require continual power in order to remain locked. In the event there is a power outage, the lock will no longer remain in the locked position. For the most part electromagnetic locks work with a DC current; either 12 or 24 volts. There are AC powered models available; however.

Some consumers may wish to utilize a battery backup in order to be sure security is maintained in the event of a power failure. If there is a power loss, the battery backup will provide continuous lock for a period of time or until electricity can be restored.

It is important to know that electromagnetic locks also generally require a credential for entry; adding another level of security for consumers. Locks are available with forces ranging from 300 to 1,500 pounds.

Many consumers see one of the best advantages of electromagnetic locks as the fact that there is no bolt or latch that can jam or stick. While the fail-safe component may be a concern for some, a back-up locking mechanism eliminates worries regarding safety in the event of a power failure. Electromagnetic locks can be combined with a variety of systems including a mortise lock set, latching exit bar or a cylindrical lock.

Be aware that local building codes can impact the installation of electromagnetic locks. This is because some locks could prevent occupants in a building from exiting the building safely in the event of an emergency. To counter that problem, some codes require hardware to be installed along with electromagnetic locks to balance safety and security. One way this can occur is with an exit lever bar. The basic idea is to provide a manual operation to reset the door.

Improvements have also been made in the construction of electromagnetic locks to prevent concerns regarding lock failure due to door frames that may sag or be uneven. This is accomplished through monitoring functions such as a door position switch or an effect sensor that will determine whether an object may have slipped between the magnet and the armature plate and ensure the lock is in fact locked and active.

Electromagnetic locks range in price from around $300 to $1,500 per door.
Another trend in electric door locks takes form in traditional hardware such as deadbolts and mortise locks that have been modified to operate electrically.

These locks are available in both standalone and hardwired versions. Full service locks that are hardwired to an access control system ranges in price from $3,000 to $5,000. It is possible to find such locks at less than $1,000; however, these are typically offline systems that require physically checking the door to collect data regarding activities. Numerous options are available in this field including a digital standalone pushbutton lock that allows code entry from outside to be blocked. Other models allow the door to be locked for short time periods until it is re-engaged from a handle located on the inside. Intelligent locks have the ability to identify the owner and gather data regarding recent activity. A central control unit provides the ability to deny access to certain keys; which can provide security in the event keys are ever lost or stolen.
