1581S Series
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.
A choice of operation mode allows users to meet their local code compliance while meeting all national and regional building and fire life safety codes, including NFPA 101, Special Locking Arrangements. All SDC delayed egress locks release immediately in an emergency.
The 1581S series locks can be utilized in single or double door applications. A remote key switch or access control must be provided to operate the reset and request-to-exit (REX) functions. For double door applications, order two 1581S locks with a tandem cable kit. The tandem cable kit enables slave operation, pushing either door leaf triggers the delayed release of both doors.
