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. Size matters. Designed to delay egress through perimeter exit doors for 15 or 30 seconds, alert security and personnel to unauthorized egress, and are compatible with access controls and patient wandering systems. In addition, the subdued alarm is less disruptive to patients and staff. SDC has also maintained all the features and status outputs found in most higher holding force delayed egress locks on the market.
