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-

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

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.

204038 Rev. C, 01/17/12

2.4.2 CYCLE the door several times, and ENSURE the 4-contact switch block assemblies on

the hanger leading edges mate properly with the center contact plate as the doors come together.

2.5 The 4-Contact Plate Assembly for Single-Slide Doors

2.5.1 Figure 4 illustrates the configuration for the left side or right side mounting.

Figure 4. Configuration for Left and Right Side 4-Contact Plate Assembly Mounting

2.5.2 Figure 5 illustrates the 4-contact plate assembly installation for Single Side Doors.

NOTE:

The 4-contact plate must align properly with the four-contact switch block assembly on the hanger to

ensure the electrical connection to the door panel. The position of the four-contact switch block assembly

can be adjusted for vertical alignment.

2.5.3 CYCLE the door several times, and ENSURE the 4-contact switch block assembly on

the hanger leading edge mates properly with the center contact plate as the door closes.

2.6 Installing the Label

2.6.1 INSTALL the Delayed Egress label “PUSH UNTIL ALARM SOUNDS. DOOR CAN

BE OPENED IN 15 SECONDS” in the center of the push bar. (If a 30-second egress is

required and approved by fire marshal, ATTACH the “30” sticker on top of the number “15” in the label.)

2.7 The Delayed Egress Assembly Wiring

WARNING

The I/O & Buzzer connections to the DE-MC521 controller and MC521 Pro controller as indicated on the Attachment 3 must be made by grounded, shielded cable.

NOTE

For DE-MC521: 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.

For MC521 Pro:The input power electrical rating for this assembly is 120-VAC, 60-Hz, and 5A. The

output power electrical rating is 17.9 ~24 VDC.

2.7.1 Refer to Attachments 2 and 3 for the appropriate delayed egress schematic and system

wiring.

2.8 Operational Checkout of the Delayed Egress System

2.8.1 Refer to appropriate controller installation manual and perform FIS. a. For DE-MC521 only:

Refer to P/N 204003, “MC521 Installation and Operation

Manual.”

b. For MC521 Pro only:

Refer to P/N 20466, “MC521 Pro Installation and Operation

Manual.”

2.8.2 SET the door for delayed egress as follows:

NOTE

The door can be set for delayed egress using either the pushbuttons or a handheld device. 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.

2.8.3 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.

204038 Rev. C, 01/17/12

MIN. GAP

NOTE:

The typical gap required between the magnet and the armature is 0.120″.

2.8.4 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.

2.8.5 If necessary, ADJUST the 4-contact switch block assemblies and ENSURE proper

alignment with the center contact plate.

2.9 Troubleshooting the Delayed Egress System

2.9.1 Refer to Table 2-3 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.

204038 Rev. C, 01/17/12

Table 2-3. 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 OR MC521 Pro. The buzzer turns ON. K2 LED is OFF. K1 LED is ON. And shear locks de-energize after 15/30 seconds.

Door set for CLOSED/LOCKED in closed position. Shear locks energize, but door panel can break out.

Check connections from push bar switches to two- contact transfer contacts to quad transfer contacts to K2 coil.

Adjustment is required on armature. Set gap to between 0.080″ and 0.120″.

2.9.2 CHECK for correct DC voltage measurements on terminal block OR PC Board

assembly as follows:

a. SET the door to CLOSED/LOCKED. b. CONNECT the negative (-) lead of the multimeter to TB2-10 of the controller. c. Refer to Table 3-4, and CHECK each terminal number of the terminal block and

relay assembly for the voltage shown.
