SDC 1581S Series Mini Integrated Delayed Egress Locks
The SDC 1581S Series Mini Integrated Delayed Egress Locks provide a compact, economical delayed egress solution for long-term care facilities, healthcare environments, and commercial buildings requiring controlled egress with a smaller and less obtrusive footprint. Designed for minimum-security applications, the 1581S delivers reliable delayed egress protection while minimizing disruption to patients, residents, staff, and building occupants.
These integrated delayed egress magnetic locks are designed to delay unauthorized egress for 15 or 30 seconds, providing security personnel with time to respond while alerting occupants with a subdued alternating alarm. The 1581S is compatible with access control systems and patient wandering systems, making it well suited for healthcare and long-term care applications where controlled exit and patient safety are critical.
Compact Delayed Egress Protection
SDC designed the 1581S Series to provide many of the functionality and status features found in larger delayed egress locks while maintaining a smaller, cleaner appearance. The compact design is ideal for perimeter exit doors where space, aesthetics, and cost are important considerations.
The 1581S provides selectable operating modes to help facilities meet applicable building and fire life safety requirements, including NFPA 101 Special Locking Arrangements. In an emergency or fire alarm condition, the lock releases immediately to provide emergency egress.

Access Control & Patient Safety Compatibility
The SDC 1581S Series integrates with access control systems while providing delayed egress and alarm functionality. It is particularly suited for long-term care, healthcare, assisted living, and commercial facilities where controlled egress and patient safety are important.
A remote key switch or access control system must be provided to operate the reset and request-to-exit (REX) functions.
Single & Double Door Applications
The 1581S can be used on both single and double door applications. For double-door installations, order two 1581S locks with a tandem cable kit. The tandem cable kit provides slave operation so that pushing either door leaf initiates the delayed release of both doors.
Optional Monitoring Features
For installations requiring additional system monitoring, the 1581S Series is available with optional status outputs:
- Door Position Status (DPS) – Provides door position monitoring for integration with access control and security systems.
- Bond Alert Status (BAS) – Provides monitoring of the magnetic lock bond condition.
Emergency Release & Code Compliance
The SDC 1581S incorporates selectable operating modes designed to support applicable local requirements while addressing national and regional building and fire life safety codes. All SDC delayed egress locks release immediately during an emergency, providing unrestricted emergency egress when required.
Applications
- Long-term care facilities
- Healthcare and medical facilities
- Assisted living facilities
- Patient and infant security areas
- Commercial buildings
- Perimeter exit doors
- Minimum-security delayed egress applications
- Access-controlled exit doors
