Frequently Asked Questions - EMDE Dormakaba

What is the purpose of the rubber washer on the armature plate bolt?

The rubber washer should project slightly beyond the armature plate surface. When power is removed, it expands to break the air vacuum between the plate and magnet, ensuring the lock releases. Do not remove or trim it.

How do I adjust the nuisance delay and release delay?

Use the DIP switches on the circuit board. Switches 2 and 3 set the nuisance delay (0, 1, 2, or 3 seconds). Switch 1 selects 15 or 30 seconds release delay (30 seconds requires AHJ approval). Refer to DIP switch tables in the manual.

What power supply is required for the EMDE lock?

A filtered and regulated DC power supply listed to UL294 or CAN/ULC-S318, rated 12 to 24 VDC. Dormakaba recommends the PS Series power supplies. The lock auto-senses voltage.

Why does the lock hum or vibrate?

Humming usually indicates the lock is operating on AC voltage or there is AC ripple in the DC supply. Use a properly filtered and regulated DC power supply to eliminate this.

How do I synchronize two EMDE locks on double doors?

Connect the two locks using the provided yellow, green, and black wire harness to the COM terminals. Set DIP switches on both locks identically. Refer to the wiring diagram on page 4 of the manual.

What is the recommended maintenance schedule?

Inspect and maintain the lock and armature plate quarterly. Clean contacting surfaces with a non-abrasive cleaner. Check all mounting fasteners for tightness. Apply thread locking compound to screws as needed.

Can the EMDE lock be used on fire doors?

Yes, the GWXT fire listing qualifies the EMDE series for use with UL Classified fire doors up to 4 ft wide and 8 ft high, rated up to 1-1/2 hours. Follow all installation instructions.

What happens if the door is forced open before the release delay expires?

The local buzzer/sounder will pulse rapidly (forced open alarm). It can only be turned off by cycling system power off and on. The lock will remain in alarm until power is reset.

How do I reset the lock after a release?

Relocking depends on local code. For most codes, a momentary normally open key switch connected to the RST input is required to manually relock. BOCA code uses a door switch that relocks after door closes and a 30-second delay.

What accessories are available for narrow or inswinging doors?

Accessories include angle brackets (narrow head jamb), L brackets (insufficient header space), filler bars (thin door stop), spacer bars (obstructions), armature holders (doors not allowing proper armature height), and top jamb brackets (inswinging doors).

Installation Instructions

1. Mount the electromagnetic lock to the door frame as outlined on the installation template included with the product.

Armature Plate Mounting Notes:

1) It is essential that this plate pivot slightly on the mounting bolt to allow proper alignment with the magnet surface. If not aligned, the lock may lose holding force or not lock at all.
2) The rubber washer on the head of the mounting bolt should project slightly beyond the surface of the armature plate. It will expand when power is removed and break the air vacuum between the plate and magnet. If removed or trimmed, the lock will appear to have some holding force even when power is removed.

For added safety, thread locking compound has been provided for the armature plate bolt and the four captive electromagnetic lock mounting screws.

WARNING: Improper installation, maintenance, inspection or usage of the product or any related accessories or parts may cause the electromagnetic lock, armature plate and associated hardware to disengage and fall, causing serious bodily injury and property damage. dormakaba Canada Inc. and/or dormakaba USA Inc. will not be liable to the installer, purchaser, end user or anyone else for damage or injury to person or property due to improper installation, care, storage, handling, maintenance, inspection, abuse, misuse or act of God or nature involving this product or any related accessories or parts.

1. Route the power supply connecting wire through the door frame and into the wire access hole in the top of the magnet housing. Connecting wire should be of sufficient gauge for the lock being installed and the distance being run. See table for current draw specifications and wiring gauge chart.
2. See system overview and switching options.

Delayed Egress System – Overview

The EMDE Delayed Egress electromagnetic lock is a fail safe device.

In the normal condition with power, the door is locked, the local buzzer is off, the local SPDT relay is de-energized and the remote alarm DPDT relay is energized.

The exit sequence is dip switch selectable for either pressure sensing on the door or a REX switch in the exit hardware. See Dip Switch 10-1. A nuisance delay period can be set for 0, 1, 2 or 3 seconds as defined by the local building code. During this period the local buzzer will pulse and the local alarm relay will be energized. If pressure on the door or hardware is released during this period the system returns to normal conditions. This would be considered accidental triggering. See Dip Switch 8-2 & 3.

If the trigger is maintained for longer than the set nuisance delay, an irreversible release delay sequence begins. This release delay is for 15 seconds, but may be extended to 30 seconds with permission of the Authority Having Jurisdiction (AHJ). It includes the short nuisance delay. Pressure is no longer required on the door. The remote relay de-energizes. The local buzzer changes from a pulse to steady. See Dip Switch 8-1.

The lock releases when the release delay time ends. The local buzzer remains on until reset and the local alarm relay will de-energize. The system relock is defined by the local building code.

All installations must be approved by the local Authority Having Jurisdiction (AHJ).

The COM input/output is used to synchronize a pair of delayed egress maglocks, for use on double doors. Use the provided wire harness; yellow, green and black. Configure DIP switch settings of both locks to the same to ensure proper operation.

PUSH UNTIL ALARM SOUNDS DOOR CAN BE OPENED IN 15 SECONDS

Several building codes including the NFPA 101 Life Safety Code and the International Building Code require the signage (shown left) to be mounted on each door close to the releasing device.

For IBC 2017 applications with inswinging doors, use the top jamb bracket accessory and the signage on the right.

PROBLEM	SOLUTION
Cannot remove the lock mounting bracket from top of magnet for installation.	Remove anti-tamper screw and cavity screw. Insert supplied Allen wrench into mounting bolt holes in the bottom of the lock housing and turn. (See Fig.1)
Lock is installed but has no holding force at all.	Check power supply. DC power should be within 12-24VDC.Check connections at power supply, connected releasing devices, lock terminals and lock circuit board to magnet core.
Lock has enough holding force to lightly hold a screwdriver or set of pliers but door will not lock.	Check to see that armature plate is correctly aligned with the electromagnetic lock. If there is improper alignment, make a 1/4" turn of the armature plate mounting bolt and check for alignment.Make sure to follow the armature plate mounting instructions on the template and Page 1 of this install.
Lock is operating and locking but the armature plate is "humming" against the surface of the lock.	This generally indicates that the lock is either operating on AC voltage or there is some AC voltage present in the DC supply. A properly filtered and regulated DC power supply is required to achieve optimal operation from the lock.
Lock is not releasing immediately upon removal of power	Ensure that switching devices are interrupting the DC power and not the AC power supply voltage.Ensure rubber washer on armature plate mounting bolt has not been removed or damaged.Remove any Diodes or other suppression devices that may be installed.
Second door doesn't release	Check COM connections per page 4.

Product Mounting Accessories Guide

Accessories may impact holding force.
