Delayed egress systems are probably the most interesting electric locking arrangements to sell, design, install and service. If you are working with a client for whom delayed egress is an option, you have a customer with something or someone to protect. I always find this kind of system more meaningful and consistent with my overall mission statement: protecting people.
Delayed egress is a special locking arrangement which initially was not widely embraced by installers and code enforcement because it created a potentially dangerous condition at an egress door by deliberately locking it.
Delayed egress systems use either latch retraction or electromagnetic locks. For several years after they went into widespread use, maglocks were frequently installed improperly, creating life safety hazards and causing fatalities. As a result, many municipalities outlawed maglocks entirely.
As time passed, the building codes caught up the electromagnetic lock, and codes were written, this began the consensus process that governs building code development and architectural component deployment. Electromagnetic locks were on the market for several years before they came under ANSI/BHMA classification or NFPA directives.
Today you will encounter delayed egress in a wide variety of applications where you will have to design systems to meet the client’s specific application, install a system already designed and approved by the LAHJ, and repair and existing system which has failed or reached the end of its life cycle.
Today, there is a greater demand for delayed egress, a wider selection of delayed egress products and an acceptance of these systems by clients, customers and building Code Enforcement community.

Delayed Egress helps prevent unauthorized exits; however, what if access control is required on the same opening? Traditionally, if delayed egress exit devices are used on an access controlled door, an electric strike or electrified lever trim must be added to the application. In certain cases, latch retraction exit devices can be used to provide access control, while using a magnetic lock to provide delayed egress. Both combinations of products accomplish the job, addressing all the concerns of the application.
There is one other option: use an exit device that includes both latch retraction and delayed egress. Delayed Egress with Latch Retraction (EExER) is designed for applications where both delayed egress and remote unlocking, remote dogging, access control or an automatic door operator are desired. A Request to Exit Switch (EX) is included for push pad monitoring. The 100 dB alarm will sound when someone attempts to exit but the door will remain locked for 15 seconds, deterring unauthorized exits and providing time to respond to the alarm.
Delayed Egress with Latch Retraction is ideal for restricted areas, access controlled doors, and any door requiring authorized entry or exit, while preventing unauthorized entry or exit. Additional applications include fire-rated, cross corridor, access controlled, delayed egress doors with automatic operators, all without using magnetic locks or electric strikes. Other applications include emergency exits at transportation terminals, such as airports, as well as controlled areas within healthcare facilities, and employee access points where staff is required to not only “badge in “but also well as “badge out”.
Detex Weatherized Delayed Egress EasyKits provide a 15-second delay and 100dB alarm when someone attempts to exit. The WDE EasyKit is ideal for garden center gates, amusement parks, sports arenas and any location exposed to weather or moisture where delayed exit is required. In applications such as outdoor childcare and assisted living homes, WDE EasyKit can also be used to help protect those trying to exit.
Components include:
• Weatherized Panic Device with delayed unlocking sounds alarm and notifies staff of exit attempt. Allows panic unlocking after 15-second delay.
• Access Control allows entry from outside with keypad or card reader.
• DX Bolts further secure outside area by preventing hinge cutting.
• Weatherized Door Prop Alarm warns that door or gate is being held open. Battery-powered or wired.

DORMA DE9000 Delayed Egress
DORMA’s DE9000 is armed and the touchbar will not activate the latch bolt for 15 seconds (30-second factory option available). This provides a controlled delayed egress while simultaneously sounding a local and remote audible alarm. After the delay time, unrestricted emergency egress is available.
The nuisance alarm, with a steady warning tone, deters inadvertent activation of the device when the touchbar is depressed. Releasing the touchbar before the predefined nuisance alarm time of 1 or 3 seconds terminates the alarm, and the device returns to the armed mode. Depressing the touchbar longer than the predefined time will initiate the 15-second irreversible delay cycle. The 1 or 3 second nuisance alarm time is included in the 15-second irreversible delay time. The nuisance alarm time is field-selectable for three seconds or one second by a dip switch. A 30-second delay option is available set at the factory. Written approval is required from the authority having jurisdiction.
Features include:
Local or Remote Alarm. The internal 85 dB alarm will sound indefinitely in the alarm state until the device is reset. Additionally, a form C relay is provided for activating remote audible/visual signaling of DORMA control console or third party console, security panel, or other audible/visual signaling device.
Indicator LED. When the device is disarmed for an extended time in the bypass mode, the LED will maintain a slow green flash. When activated for authorized egress, the LED displays a rapid green flash until the device automatically rearms. In the armed state, the LED maintains a solid green. When the touchbar is depressed for exit, the nuisance alarm will sound while the LED remains solid green. In the 15-second irreversible delay cycle, the LED turns solid yellow. In the alarm state, the LED is solid red.
Key Switch Control. This integral key switch provides the means to locally rearm the device from the alarm state, disarm for authorized egress, and set the device for the bypass feature. A mortise cylinder is supplied with the device.
Remote Authorized Egress. This function allows override of the device in the armed state. The device will unlock for egress and automatically rearm to the delayed egress mode in 10 seconds. The field-selectable reset time allows up to a 20-second reset. Typical activation devices include remote consoles, key switches, or card readers. This input is controlled with a momentary action normally open switch.
Remote Rearm. Remote rearming of the device is allowed from the alarm state. Typical activation devices include remote consoles or key switches. This input is controlled with a momentary action normally open switch. Consult LAHJwhen using this feature.
Door Position Input. An input for use with an external door position switch is provided. This input switch is a maintained action normally closed contact. The device alarms simultaneously with the contact opening. The door is prohibited from being forced or held open unauthorized while the device is armed. The field-selectable authorized egress and bypass functions ignore the door position input for authorized exit or entrance.

SDC Delayed Egress Products
SDC’s new Exit Check® S6000-101 All-In-One delayed egress panic and fire exit device comes with controller and delayed egress logic all integrated into the bar. Available in rim mount, mortise and vertical rod (surface mount & concealed) configurations, the All-In-One is designed for retail loss prevention, pedestrian control, wandering patient control and nursery infant protection.
Audible alarm and multi-colored LEDs provide alert to unauthorized egress when initiated by depressing the push pad. A key switch provides reset and bypass control. In a life safety emergency, the device will immediately unlock upon loss of power or when powered by a fire control supervised power supply.
When unauthorized egress is initiated by depressing the push pad of the S6000-101, an audible alarm will sound and an irreversible unlock delay period of 15 seconds will begin. Meanwhile, the person exiting must wait to egress, allowing personnel or security time to respond to the alarm. After the delay period has expired, the device unlocks, permitting egress until the device is reset.
In a life safety emergency, the device will immediately unlock upon loss of power or when powered by a fire control supervised power supply.
