Delayed Egress Applications For Hospitals

Delayed egress locking mechanisms can provide an additional level of safety for newborn and infants in the nursery and for and patients in psychiatric wards or Alzheimer’s units.

Suggestion: Bring along a smartphone or iPad to obtain installation instructions from the manufacturer’s web site while at the jobsite.

The 57-80 Series delayed egress exit device’s audible and visual indicators show door lock status. Depressing the push rail for two seconds or longer initiates an irreversible alarm. The alarm sounds during the adjustable time delay of 0-30 seconds during an unauthorized egress.

After the time delay, the alarm continues to sound while the mechanism in the exit device releases and the door can be opened. The delayed egress exit device is disarmed with the key. When wired into the building’s fire alarm system, a relay in the circuitry voids the delayed action cycle, allowing for immediate egress in an emergency.

The SARGENT 57-80 Series has a micro-switch along the base of the Insert Mechanism with an access hole in the bottom of the rail. The micro-switch adjusts the triggering point for the delay process. The push bar is designed to move about one-half inch before being stopped by the magnetic connection stopping the bar from being able to retract the Pullman latch. If the delayed egress process does not start within the half inch of travel, it will not start at all. The micro-switch is adjusted to activate the alarm within the half-inch of travel.

For authorized access and egress without activating the alarm, an HES 9500 Series was installed. Presenting an authorized work identification card to the reader on each side of the doorway activates the electric strike to electronically release the Pullman latch from the keeper without activating the alarm.

The latch bolt monitoring circuitry in the exit device has been disabled to permit authorized access and egress. The Pullman latch is pushed into the center case as the door closes and released once within the keeper. If latch bolt monitor were not disabled, the bar would go into alarm each time the door closes.

As an added layer of security, the newborn/infant section has Hugs Infant Protection beginning in the delivery room. The Hugs tag is attached to each infant’s ankle and is monitored.
