6000 Series MELR Exit Devices Installation Instructions

1. Overview

The Commercial Motorized Electric Latch Retraction (MELR), see Figure 1, works with the 6000 series exit devices (6100, 6130, 6150, 6160, 6170, 6200, 6210, 6250, 6220) to provide remote-controlled latch retraction option. It is compatible with the following:

• "S" Latchbolt Position Monitor: Provides indication of the position of the latch bolt. Used with security systems to monitor the latch bolt. Also used to activate automatic door operators upon latch retraction.
• "B" Touchbar Monitor: Provides indication of the pushbar being depressed. Used as a request to exit to shunt alarm systems, release electromagnetic locks or monitor egress.
• "O" Trim Monitor Switch Provides indication of the device being operated from the outside. Used as a request to enter signal switch to shunt alarms. Also used to monitor entry.

NOTE: The MELR option is also compatible with hex key, cylinder key and fire rated mechanical configurations.

A. Functions

The MELR option can be configured to work in either of two modes:

• Power Mode (See Section 2, Page 10): The device is not energized when locked. When power is applied, the pushbar and latch(es) will retract and remain in the retracted position until power is removed. Power is typically applied through a relay triggered by an access control device.
• Timer Mode (See Section 3, Page 15): The device is always energized and retraction is triggered by a momentary or maintain switch.

When the timer circuit is closed using a momentary switch, the device retracts, remains retracted for a set duration, and releases. The duration of the retraction is set through an onboard timer setting.

When the timer circuit is closed using a maintain switch, the device retracts. The device releases when the contact is opened.

Caution: Disconnect all input power before servicing.

• Installer must be a trained and experienced service person.
• Wiring must comply with applicable local electrical codes, ordinances and regulations.
• Hex key or cylinder (6XX5) mechanical dogging CANNOT be used on Fire Rated Doors.

Refer to applicable 6000 Series Exit Device product instruction sheet to correct mechanical installation issues.

IMPORTANT:

* ALWAYS disconnect power before making any mechanical adjustments to the system.

Table 6 - Power Mode Troubleshooting

The pushbar does not move when 24V input is applied:

• Check inputs to confirm proper voltage and wiring orientation (Figure 6 ElectroLynx Power Mode Installation).
• Remove end cap from pushbar and confirm that LED is blinking steadily when power is applied. If not, refer to LED signaling.

NOTE:

When configured in Power Mode, power is released to lock the device (LED will not blink when power is released).

Confirm DIP switch position 3 is set to ON.

The pushbar does not fully retract or pushbar retracts completely and holds but does not open door:

• * Verify mechanical installation and correct as necessary:
  • − Is excessive force required to depress the pushbar?
  • − Are latches fully clearing the strikes when mechanically cycled?

The pushbar retract and unlocks electrically but does not relock:

• Physically disconnect power from pushbar and confirm that input is off.
• *Check for mechanical interference (e.g., warped door, lack of shims, misalignment of pushbar, etc.).

Rail behaves abnormally (multiple cycles, clicking, delayed retraction, etc.):

Remove end cap from pushbar and confirm that LED is blinking steadily when power is applied. If not, refer to LED signaling.

NOTE:

When configured in Power Mode, power is released to lock the device (LED will not blink when power is released).

IMPORTANT:

* ALWAYS disconnect power before making any mechanical adjustments to the system.

The pushbar does not move when 24V input is applied:

• Check inputs to confirm proper voltage and wiring orientation. When configured for the timer Mode, 24V must be constantly applied and the timer circuit must be closed to cycle the device.
• Remove end cap from pushbar and confirm that LED is blinking steadily when power is applied. If not, refer to LED signaling.

The onboard timer duration adjustment is not working:

• Remove power when making adjustments to time delay settings (DIP switches).
• When a momentary signal is applied to timer circuit, circuit must be reopened for timer to function.

The pushbar does not fully retract or pushbar retracts completely and holds, but does not open door:

• *Verify mechanical installation and correct as necessary:
  • − Is excessive force required to depress the pushbar?
  • − Are latches fully clearing the strikes when mechanically cycled?

The pushbar retracts electronically but does not release. System does not relock:

• Confirm that Timer Mode contact is opened ( the pushbar will remain depressed until contact is opened and delay has expired.)
• Physically disconnect power from pushbar (While electronically retracted,) to verify if issue is mechanical.
• Check for mechanical interference (e.g., warped door, lack of shims, misalignment of pushbar. etc.)

Rail behaves abnormally (multiple cycles, clicking, delay retraction, etc.):

• If a momentary contact is applied to time circuit, adjust onboard timer to a longer duration.
• Remove end cap from pushbar and confirm that LED is blinking steadily when power is applied. If not, refer to LED signaling.
