SDC’s ExitCheck delayed egress locks continue to be the premier delayed egress offering on the market. The patented design revolutionized delayed egress by incorporating an alternating verbal message, verbal countdown and alarm tone, plus a large digital countdown display and door release indicator to provide a clear warning for the safety of persons without prior knowledge of door operation, including the blind and hearing impaired. 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. 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. A variety of field selectable options allow for field selectable voice message and alarm tone, or alarm tone only; field selectable activation on door movement; exit device with switch kit; or pressure sense bars for non-latching doors; field selectable automatic or manual relock upon power up after emergency release or power loss; and a field selectable door prop alarm sounds when door is left open after the selected bypass time has elapsed. The 1511T series incorporates all ExitCheck features for double door applications through a slave lock output to enable the use of two units for pairs of doors to ensure pushing either door leaf will cause both doors to release.

Models:

• 1511T: Tandem delayed egress lock

Applications:

• Typically used on exit doors, when unauthorized egress is initiated in the locked mode, SDC's ExitCheck locks delay egress through the door for 15 or 30 seconds. Meanwhile, the person exiting must wait while personnel or security respond. The door unlocks after 15 seconds have elapsed, permitting egress. A signal from the fire life safety system will release the lock for uninhibited egress in an emergency. 30 second delay available where approved.
• Built-in Activation for Latching Doors: The mechanical latch mechanism must be locked on the exterior and unlocked on the interior. From the inside, retracting the door latch and applying pressure causes limited door movement. The built-in activation trigger senses the door movement and initiates delayed egress operation. The adjustable sensor helps prevent false triggering.
• External Activation for Latching Doors: Where preferred, activation may be accomplished by a latch monitoring strike or a switch installed in a standard latching exit device or lockset. A power transfer device is required for exit devices equipped with a trigger switch.
• External Activation for Non-Latching Doors: The external activation trigger input must be used with doors without latch assemblies, such as latch less glass and Herculite doors. Activation may be triggered by SDC's MSB550 or PSB560 series egress bars. A power transfer device is required. Pushing on a request-to exit egress bar immediately activates the delayed egress operation.
• Auto Power-Up: When selected, regardless of the means of deactivation, relocking of the ExitCheck occurs when power is restored and/or the fire life safety panel is reset.
• Manual Power-Up: UBC, California building code (OSHPD) compliant reset. When selected, regardless of the means of deactivation, relocking of the ExitCheck is by manual means only at the door. Only after power restoration and/or fire life safety panel reset, the door may be relocked by actuating the standard built-in key reset or optional wall mounted key switch, push switch or digital keypad located adjacent to the door.
• Keyless Control: Although equipped with a standard built-in four function key switch for reset, manual power up, momentary bypass and sustained bypass functions, the SDC 920 wall mounted keypad provides the convenience of keyless operation for alarm reset, manual power-up, momentary bypass and sustained bypass functions.
• Airport and Public Facility Security and Safety: Control pedestrian traffic in government, public and transportation facilities, including airport jetways and tarmacs.
• Loss Prevention: Provide theft protection of retail merchandise, technology and other valuables, such as art and museum artifacts.
• Access Control: Access controls may be utilized for authorized egress, access and lock reset. Access from the exterior of latching doors requires an additional means of mechanical lock release, such as a mechanical key or electric strike.
• Wandering Patient and Infant Protection: Restrict the egress of psychiatric and drug rehab patients, elderly patients in assisted living facilities and restrict the movement of nursery infants for their own safety and security.
• Patient and Infant Tracking Systems: The SDC ExitCheck is compatible with patient tracking systems like those used for protection against infant abduction from hospital nurseries and for the protection of patients in long term care facilities who may be endangered if they leave their care facility without supervision.
