Back to Basics: Electromagnetic Locks

In 1983, SDC’s EMLock® design became the standard in electromagnetic locking innovation. EMLocks were the first electromagnetic lock to feature an interlocking quick mount assembly with captive mounting screws to simplify installations. With a second-to-none complimentary offering of mounting brackets, kits and hardware, EMLocks can meet virtually any application.

It is no wonder “EMLock” is used synonymously for premium electromagnetic locks throughout the industry today. Over the years, SDC’s
electromagnetic product offering has expanded to meet narrow header, sliding door, gate, cabinet and hazardous applications. The Excel™ product line is our fully featured, economical alternative to low-cost imports.

Mini Integrated Delayed Egress Locks

SDC’s 1581S series mini delayed egress locks are designed to meet the needs of long term care and commercial facilities that require a smaller, less obtrusive, and less expensive delayed egress lock that is better suited for minimum security needs.

The 1581S series delays egress through perimeter exit doors for 15 or 30 seconds, alerts security and personnel to unauthorized egress, and is compatible with access controls and patient wandering and infant tracking systems.
