1. PURPOSE
1.1 Discussion
This manual provides installation instructions for the Stanley Dura-Glide Delayed Egress system
Model DE-MC521. The delayed egress system provides a controlled egress for openings which
require panic or fire hardware for safe egress. This solution has been designed to aid in loss
prevention at retail locations by denying egress for a set time period.
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 1
second. (Accidentally pushing the panic bar or touching it for less than the nuisance delay time
of 1second will not sound the alarm. This nuisance delay time helps avoid inadvertent
activation.) The alarm will sound when the panic bar is pressed, but the alarm sequence will not
start unless the panic bar is held in for more than the nuisance delay time. An audible alarm
sounds after pushing the panic bar for longer than the nuisance delay. This initiates an
irreversible sequence for 15 or 30 seconds until the device releases. After the delay 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. The
individual who pushes the panic bar is denied egress for 15 or 30 seconds.
1.2 Applicability
This manual is ONLY applicable to the Stanley Dura-Glide DE-MC521 Delayed Egress system.
Standard MC521 slide installation manual is a pre-requisite for this installation manual.
Instructions for installing Transom installation, 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. The Transom installation and optional
accessories have not been evaluated by UL for use with the DE-MC521 Delayed Egress System.
1.2.1 The delayed egress system includes the following components and functions:
•The MC521 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 MC521
controller. The input range must be greater than 20.2 Vdc.
•The four-contact 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 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.

3.7 Wiring the Delayed Egress Assembly
WARNING
All connections to the DE-MC521 controller (Part No. 516928) as indicated on the Attachment 3 must be
made by grounded, shielded cable.
Only the connections shown on the schematic in Attachment 2 have been evaluated by UL.
NOTE
The input power electrical rating for this assembly is 120-VAC, 60-Hz, and 5A. The output power
electrical rating is 14.7 ~ 20.2 VDC.
Power-limited Class 2 wiring must maintain 1/4" separation from non-power-limited Class 1 wiring.
3.7.1 Refer to Attachments 2 and 3 for the delayed egress schematic, and CONNECT system
wiring as shown.
3.8 Operational Checkout of the Delayed Egress System
3.8.1 Refer to 204003, “MC521 Installation and Operation Manual.” Perform FIS. Then SET
the door for delayed egress as follows:
NOTE
The door can be set for delayed egress using either the pushbuttons or the Palm. The following steps
describe setting delayed egress using the pushbuttons.
•INDEX 18. Value 00 is OFF (not evaluated by UL).
•INDEX 18. Value 01 is 15 sec.
•INDEX 18. Value 02 is 30 sec.
3.8.2 CYCLE the doors several times and ENSURE the following features function properly:
•The 1-second nuisance delay functions properly.
•The buzzer alarm sounds.
•The 15- or 30-second delay-of-egress period functions properly.
NOTE
The typical gap required between the magnet and the armature is 0.120″.
3.8.3 If shear locks do not engage, refer to Figure 6 and, using the key wrench supplied with
the lock kit, ADJUST the shear lock assembly. After adjusting the armature, remove the
armature and tighten nuts at the bottom. Reassemble.

3.8.4 If necessary, ADJUST the 4-contact switch block assemblies and ENSURE proper
alignment with the center contact plate.
3.9 Troubleshooting the Delayed Egress System
3.9.1 Refer to Table 3-3 for a listing of symptoms and remedies.
NOTE
The following two conditions describe proper system operation:
1. Door is in CLOSED/LOCKED. The buzzer is OFF. The shear locks are energized. K1 LED is OFF. K2
LED is ON.
2. Door is in AUTOMATIC. The buzzer is OFF. The shear locks are de-energized. K1 LED is ON. K2
LED is OFF.
Table 3-3. Symptoms and Remedy
Symptom Remedy
Door set for CLOSED/LOCKED and door gets to
closed position. Delayed egress starts without
pressing push bar. The dE indication is displayed on
MC521. The buzzer turns ON. K2 LED is OFF. K1
LED is ON. And shear locks de-energize after 15/30
seconds.
Check connections from push bar switches to two-
contact transfer contacts to quad transfer contacts to
K2 coil.
Door set for CLOSED/LOCKED in closed position.
Shear locks energize, but door panel can break out.
Adjustment is required on armature. Set gap to
between 0.080″and 0.120″.
