Frequently Asked Questions - RCI EW8310 Dormakaba

How does the Early Warning system work?

The Early Warning system provides a nuisance delay of 4 seconds when pressure is applied to the door. If pressure is maintained, a 30-second remote alarm period is triggered. The system monitors for forced entry and provides visual and audible alerts.

What is the failure mode of the EW8310 lock?

The lock is fail safe, meaning it unlocks when power is removed. A mechanical latching device is recommended to maintain security during power outages.

How should the armature plate be aligned?

The armature plate must pivot slightly on its mounting bolt to align with the magnet surface. The rubber washer should project slightly beyond the plate surface to break the air vacuum when power is removed.

What should I do if the lock hums?

Humming usually indicates AC voltage present in the DC supply. Use a properly filtered and regulated DC power supply.

How can I reset the alarm after a forced entry?

The system must be reset by shutting off power to the lock. After restoring power, the lock will return to normal operation.

Can the lock be installed outdoors?

No, the lock is designed for indoor use only. It is not rated for outdoor environments.

What maintenance is required?

Inspect quarterly: clean contacting surfaces with a non-abrasive cleaner, check all mounting fasteners, and ensure armature plate feels secure.

Are accessories available for different door configurations?

Yes, various accessories such as angle brackets, L brackets, filler bars, spacer bars, and armature holders are available for narrow jambs, hollow metal frames, and other situations.

What relays are provided for alarm signaling?

The lock has a Local Alarm SPDT relay and a Remote Alarm DPDT relay. Their states depend on the alarm condition.

How do I choose the correct wire gauge?

Use the provided wire gauge table based on total wire length and load current. For example, at 24V and 1/2A, 18 AWG is suitable for up to 200 ft.

Early Warning System – Overview

The Early Warning electromagnetic lock is a fail safe device.

In the normal condition with power, the door is locked, the light panel blinks green, the Local Alarm SPDT relay is de-energized and the Remote Alarm DPDT relay is energized.

The alarm sequence starts with a direct pull on the door.

A Nuisance Delay is set for 4 seconds. During this time the light panel will blink red and the Local Alarm relay will be energized to warn that someone is attempting to force open the secured lock. If the pressure on the door is withdrawn during the Nuisance Delay Period, the system returns to normal conditions. This would be considered accidental triggering.

If pressure is maintained past the Nuisance Delay Period, the Remote Alarm Period of 30 second will begin. In addition to the light panel blinking red and the energized Local Alarm, the Remote Alarm relay will now be de-energized.

At the end of the 30 second Remote Alarm Period, if the pressure has been withdrawn, the Local Alarm relay will return to the normal condition. The light panel however will continue to flash red and green until reset. The Remote Alarm relay will remain off until reset. If pressure is reapplied to the door, the system goes directly to the 30 second Remote Alarm Period activation of Local Alarm Relay.

If the door is forced open, the light panel will immediately blink red, the Local Alarm relay will be energized and the Remote Alarm relay will be de-energized. Even if the door is subsequently closed, all indicators will remain activated until the system power is turned off.

Easy connections are provided for an external sounder or buzzer. At an accidental triggering, an audible pulse is generated with a steady sound during the 30 second Remote Alarm period. A forced open status will provide a pulsing sound until reset.

Request to exit connections and access control wiring are detailed on pages 4 and 5.

Anti-Tamper Feature - Two screws prevent insertion of an Allen wrench into the captive mounting screw opening on the bottom of the lock. Fig. 1 shows their location. One screw also secures the wiring cavity cover. The mounting plate cannot be separated from the lock without removing these two screws.

Fig. 2 – Power Connections

To Ensure Instant Release All switching devices must be wired in between the DC power source and the positive terminal of the lock as illustrated in Fig 2.

Switching the negative power supply line will not allow the lock to release immediately. RCI electromagnetic locks contain MOV's for surge suppression and do not require any additional suppression to be added during installation. The installation of diodes across the lock input terminals will cause a delay in release.

Low Voltage Detection

Each circuit board includes a low voltage detection circuit that is enabled when shipped from the factory. This feature will cause the Local Alarm relay and status LED to activate and the Remote Alarm relay to de-energize should the lock input voltage drop below 9.0VDC. That signals a monitored system or guard station that the holding force of the lock may have been compromised.

EW8310 Early Warning Series Troubleshooting Guide

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 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.Check that switching device interrupts the positive wire and not the negative wire (See Fig. 2).Remove any Diodes or other suppression devices that may be installed.
