  • Access controlled doors are used to provide authorized personnel entry to controlled areas or buildings.

    Operation:
    Access controlled doors are normally locked and access is gained by using a card reader or a keypad for authorized entry.
    Free Egress is by manual means of unlatching mechanical hardware or electrical means of unlocking. Free egress with Electrified locksets, electrified exit bars and electric strikes is by turning lever or pushing exit bar. Free egress with Emlocks is provide by motion detector and override button. Emlocks systems are connected to Fire/Emergency system for immediate unlocking in emergency situations.

    x Solution 6 - Single access controlled Code compliant door using an Emlock, Keypad, Motion detector, and an Override Exit button.

  • Delayed Egress units, where allowed by AHJ, are typically used on exit doors to restrict access in airports, deter theft in retail stores and restrict egress of patients in care and treatment facilities.

    Operation:
    The Delayed egress unit is typically locked at egress door. When an unauthorized egress is attempted, the delayed egress unit alarms and begins an irreversible timer countdown of 15 seconds (or 30 seconds) to release. The person attempting to exit is delayed at the door. The system is connected to Fire/emergency system for immediate/uninhibited egress in emergency situation.

    Drawings:
    x Solution 7 - Single door integrated 1511S Delayed Egress Emlock unit with optional Remote release, monitoring, and LED indicator light bar
    x Solution 8 - Single door Delayed Egress Panic exit bar (S6000DE) with optional Remote release, monitoring, and LED indicator light bar.

  • Interlocks are typically used for vestibules and laboratories to control air flow or restrict number of doors open at the same time. Mantraps are typically used for secure areas requiring restricted and controlled access and egress.

    Operation:
    Both Interlock A and Mantrap B do not allow more than one door open at a time.

    Interlock A - The doors are normally unlocked and opening any door causes the other doors to lock until the open door is closed. When all doors are closed, they are all unlocked.

    Mantrap B – The doors are normally locked. Access to any door is by proximity card reader, keypad or surveillance personnel allowing entry.

    When one door is open, the access input for all other doors is disabled. When the open door is closed, access from all doors is enabled again.

    Drawings:
    x Solution 9 - Two Door Interlock A using Emlocks, controller board, LEDs and Override Pull stations.
    x Solution 10 - Three Door Interlock A using Emlocks, controller board, and override buttons at each door.

The Pre-Built Systems Library provides a choice of several Complimentary system wire diagrams for common single and double door applications. Drawings vary with choice of different locking hardware and access and egress controls. Several of the same or different drawings may be used to accommodate multi-door system requirements.

Website visitors can use the drawings as a guide to assist in system specification.
