Security Door Controls

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.

Models:

• 1581S: Mini 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. Pushingon 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 requires a wall mounted key switch, push switch or digital keypad located adjacent to the door to relock.
• Keyless Control: 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.
