Delayed Egress locking systems are special locking arrangements used for applications where security requirements must be mitigated with life safety concerns, not where life safety requirements must be mitigated with security concerns.
They are used for loss prevention applications to discourage unauthorized egress. (Retail shrinkage accounts for more than $27 billion in loss annually.) In commercial applications, there are always doors which provide a potential escape route for shoplifters and other evil-doers, even if they are under video surveillance.
Delayed egress also is used for traffic control to discourage passback or to force card holders to use an egress reader through secured openings.
The purpose of anti-passback is to prevent a card holder from passing back his or her card to a second person to gain entry into an access-controlled area. Piggybacking occurs when an authorized person allows (intentionally or unintentionally) others to pass through a secure door, negating the purpose of an access control system such as keypad, pass card or biometric identification scanner.
Without delayed egress, it can be nearly impossible to track who is inside an area and to log users’ movements, as well as to prevent passback or piggy-backing through secured openings.
It is universally against code to prevent free egress. However, under special arrangements and conditions, it may be allowable to delay egress a little bit. Even a short delay provides enough time to alert authorities in the case of a theft, and create an embarrassing alarm situation in the case of a lazy or devious employee.
I have been installing delayed egress systems since the1980s. Initially there were only a few delayed egress systems on the market, and local authorities having jurisdiction (LAHJs) and building inspectors were unfamiliar with these locking systems and therefore reluctant to approve them.
These days there are plenty of delayed egress hardware on the market, but you still have to get an approval from your LAHJ (s) before you spec, sell or install them.
RCI DELAYED EGRESS
Rutherford Controls' new Delayed Egress maglock, the DE 8310, is a combination of their #8310 electromagnetic lock and an integrated delayed egress control module.
The 8310 is a multi-purpose electromagnetic lock used to enhance building security and install quickly.
Several standard features are provided with the intention of making these magnets the “workhorse” of the industry.
The adjustable mounting bracket has been enhanced with keyhole mounting to support the magnet’s weight during initial installation, freeing the installer’s hands to affix the magnet mounting screws. The removable cavity cover offers quick, easy access to wiring.
