1. PURPOSE
1.1 Discussion
This manual provides installation instructions for the Stanley Delayed Egress system for Model
DE-MC521 and Model MC521 Pro. The delayed egress system provides a controlled egress for
openings which require panic or fire hardware. This solution assists in loss prevention at retail
locations by denying egress for a set time period of 15 or 30 seconds.
Setting the key function switch to the “CLOSED LOCKED” or “ONEWAY” or “REDUCED
ONE WAY” position energizes the shear magnets and secures the door in the locked mode.
Activation of the delayed egress system occurs when the panic bar is pushed and held for more
than one second.
NOTE:
Accidentally pushing the panic bar or touching it for less than the nuisance delay time of one
second will not sound the alarm. This nuisance delay time helps avoid inadvertent activation.
If the panic bar is HELD LONGER than one second, an audible alarm sounds and the
IRREVERSIBLE delayed egress sequence begins. After the delayed egress time of 15 or 30
seconds, the lock releases and the alarm continues to sound until it is reset with setting the key
function switch to HOLD OPEN, AUTOMATIC, or REDUCED OPEN.
1.2 Applicability
This manual is applicable to the Stanley DE-MC521 and MC521 Pro. Either a standard MC521
OR MC521 Pro installation manual is a prerequisite for this installation manual. Installation
instructions for transoms, optional accessories such as access control locks, access control
consoles, key switches, door alarm contacts, push plates, and door position switches are
provided in separate installation manuals.
1.2.1 The delayed egress system includes the following components and functions:
The DE-MC521 or MC521 Pro controller mounted in the header provides the
logic for the egress, nuisance, and reset cycles
The two UL FWAX2 Listed shear magnet locks provide locking for up to 1200
lbs of shear force. Each two-piece lock assembly includes a magnet mounted to
the underside of the hanger and an armature mounted to the top of the panel rail.
The UL Recognized audible alarm mounted in the header connects to the DE-
MC521 or MC521 Pro controller.
The four-contact plate assembly mounted in the center of the header transfers
power from the header to the hanger. The four-contact assembly is wired to a
terminal block assembly OR to the PC Board I/O assembly (depending on
controller choice) for shear lock control and push bar switch monitoring.
The two-contact assembly mounted to each hanger transfers signal from the push
bar switch to the hanger when the doors are closed.
The recessed panic bar mounted to each door panel activates the egress cycle
when pushed.
