SDC 1511T Series Tandem Integrated Delayed Egress Locks

The SDC 1511T Series ExitCheck® Tandem Integrated Delayed Egress Locks provide an advanced delayed egress solution for double-door and pair-of-door applications where controlled egress, security, and life safety are critical. Combining electromagnetic locking with integrated delayed egress electronics, audible/visual occupant notification, and flexible programming, the 1511T helps prevent unauthorized egress while providing immediate emergency release.

Designed to provide a selectable 15- or 30-second egress delay, the 1511T uses a large digital countdown display, door release indicator, alternating verbal message, verbal countdown, and alarm tone to clearly communicate the exit condition. These features help ensure that occupants understand the door operation even without prior knowledge, including individuals who are blind or hearing impaired.

The tandem configuration is specifically designed for pairs of doors. A slave lock output allows two 1511T units to work together so that pushing either door leaf causes both doors to release, providing coordinated delayed egress operation across the entire opening.

The SDC 1511T is compatible with access-control systems, patient wandering systems, and patient or infant tracking applications. Field-selectable operating modes provide flexibility for local code requirements while supporting national and regional fire and life-safety requirements, including NFPA 101 Special Locking Arrangements.

Tandem Double-Door Operation

The SDC 1511T Series is engineered specifically for openings with two door leaves. The tandem configuration uses a slave lock output to coordinate two units, ensuring that activation at either door leaf causes both locks to release together.

This coordinated operation provides consistent delayed egress control across double-door openings and helps prevent one door from being released while the other remains secured.

Flexible Delayed Egress Operation

The 1511T provides multiple field-selectable options to accommodate different security and life-safety requirements. Installers can configure the lock for:

  • Voice message with alarm tone or alarm tone only
  • Activation upon door movement
  • Exit device activation with switch kit
  • Pressure-sensing bars for non-latching doors
  • Automatic or manual relock following power restoration
  • Automatic or manual relock following emergency release or power loss
  • Sustained or timed bypass
  • Door prop alarm after the selected bypass period
  • Security or safety messaging
  • Single- or multi-door zone control

All SDC delayed egress locks are designed to release immediately during an emergency, helping maintain safe egress while providing controlled access during normal operation.

The SDC 1511T can be configured with additional monitoring and programming options, including:

  • Energy Saver / Low-Power Operation
  • Door Position Status (DPS)
  • Bond Alert Status (BAS)
