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.
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.
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.
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
The two UL FWAX2 Listed shear magnet locks provide locking for up to 1200
The UL Recognized audible alarm mounted in the header connects to the DE-

2.3 Installing the Components on the Header Cover or Jamb (if necessary)
2.3.1 INSTALL power key switch assembly as follows:
If installation is a Dura-Glide 3000, Refer to 203926, “Rotary/Key Switch
Instruction Manual,” for machining template and MOUNT power key switch
assembly to header cover.
If installation is a Dura-Glide 2000, Refer to 203926,“Rotary/Key Switch
Instruction Manual,” for machining template and MOUNT power key switch
assembly to header or jamb inside of building.
2.3.2 INSTALL rotary key switch assembly as follows:
If installation is a Dura-Glide 3000, Refer to 203926, “Rotary/Key Switch
Instruction Manual,” for machining template and MOUNT rotary function key
switch assembly to header cover.
If installation is a Dura-Glide 2000, Refer to 203926,“Rotary/Key Switch
Instruction Manual,” for machining template and MOUNT rotary key switch
assembly to header or jamb inside of building.
2.4 The 4-Contact Plate Assembly for Bi-parting Doors
2.4.1 Figure 3 illustrates the 4-contact plate assembly for Bi-parting Doors
Figure 3. The 4-Contact Plate Assembly for Bi-parting Doors
NOTE:
The 4-contact plate assembly must align properly with the two 4-contact switch block assemblies on the
hangers to ensure the transfer of electrical connections to the door panels. The position of the four-contact
switch block assemblies can be adjusted for vertical alignment.
