1 Overview
a Description
The Corbin Russwin Motorized Latch Retraction (MELR) works with PED4000/PED5000 Series exit devices to provide remote-controlled latch retraction. It is compatible with the following prefixes/options:
- • M91 Latchbolt Monitor Switch: The latch monitor provides tamper resistant latch monitoring. The monitor switch is activated when there is physical movement of the latch.
- • M92 Signal Switch (Request to Exit): This signal switch monitors the touch bar position. Touch bar monitoring can be used to detect egress, sound an alarm, send a signal to a remote location, or de-energize an electromagnetic lock.
- • M93 Outside Exit Trim Lever Monitor Switch
- • 8910PT (Narrow Ecoflex Trim Fail Safe w/o Key Override) / 8930PT (Narrow Ecoflex Trim Fail Secure w/o Key Override)
- • 8903PT (Narrow Ecoflex Trim Fail Safe w/ Key Override) / 8905PT (Narrow Ecoflex Trim Fail Secure w/Key Override)
- • 9910PT (Wide Ecoflex Trim Fail Safe w/o Key Override) / 9930PT (Wide Ecoflex Trim Fail Secure w/o Key Override)
- • 9903PT (Wide Ecoflex Trim Fail Safe with Key Override) / 9905PT (Wide Ecoflex Trim Fail Secure with Key Override)
- Operating Temp: -40°C to 66°C (-40°F to 150.8°F)
Note: The MELR is also compatible with fire rated (A suffix) as well as M52 and M114 mechanical quick code options.
b Functions
The MELR can be configured to work in either of two modes:
- Power Mode (See Section 2): The device is not energized when locked. When electrified, the push rail 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): The device is always energized and retraction is triggered by a momentary or maintain switch. In TIMER MODE:
- 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. Cylinder (M52) or "hex-key" (M114) mechanical dogging cannot be used on fire rated doors.
c Installation Notes
- The MELR rail works only with Corbin Russwin PED4000/PED5000 Series exit devices.
- Always perform mechanical installation using the appropriate installation instructions, prior to electrical wiring.
- If used in conjunction with PED4000/PED5000 Series MELR Motor Kit or PED4000/PED5000 Series MELR Rail Kit, consult factory prior to using these instructions.
- Earth Ground: Required for electrostatic discharge (ESD) protection, unless already grounded through the metal door and frame.

Prior to electrical troubleshooting, confirm that the mechanical system properly functions; i.e., that the push bar fully retracts all latches and the door opens freely. Refer to applicable Corbin Russwin PED4000/ PED5000 Series Exit Device product instruction sheet to correct mechanical installation issues.
Important: ALWAYS disconnect power before making any mechanical adjustments to the system.
The push rail does not move when 24V input is applied:
- Check inputs to confirm proper voltage and wiring orientation (See Figure 1 on page 9: ElectroLynx Power Mode Installation).
- Remove end cap from rail 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 push rail does not fully retract or push rail retracts completely and holds but does not open door:
-
Verify mechanical installation and correct as necessary:
- Is excessive force required to depress the push bar?
- Are latches fully clearing the strikes when mechanically cycled?
The push rail retracts and unlocks electrically but does not relock:
- Physically disconnect power from rail and confirm that input is off.
- Check for mechanical interference (e.g., warped door, lack of shims, misalignment of rail, etc.).
- Was a PED4000/PED5000 Series motor kit installed? Verify the rail assembly.
Rail behaves abnormally (multiple cycles, clicking, delayed retraction, etc.):
• Remove end cap from rail 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.

d Typical Wiring
For use when wiring in Timer Mode (using the onboard timer). If more than 20 seconds timed delay is necessary, an external timer delay relay is required (not provided).
Note: 24V supply is constant in Timer Mode . Refer to settings in Section 3-g Configuration Instructions DIP Switch Settings (for M91and timer duration).
e Timer Mode Adjustment (Onboard Timer)
How it works: The 24 volt input is always energized and the system retracts when the timer input circuit is closed.
- When the timer circuit is closed utilizing a momentary switch, the device retracts, remains retracted for a set duration, and releases. The duration of the retraction is set using an onboard timer setting (0 - 20 second timer adjustment).
- The countdown begins when the rail is first retracted.
- When the timer circuit is closed using a maintain switch, the device retracts.
- The device releases when the circuit is re-opened.
Notes:
- 24V supply is constant in Timer Mode . The duration of retraction is determined by whichever is longer: the maintain switch closure or the onboard timer delay.
- If more than 20 seconds delay is necessary (exceeding the maximum setting), an external timer delay relay is required (not provided).
- Refer to settings in Section 3-g (Fig. 18-20) for DIP Switch timer delay settings.

i Timer Mode Troubleshooting
The onboard timer duration adjustment is not working:
- Remove power when making adjustments to timer delay settings (DIP Switches).
- When a momentary signal is applied to the timer circuit, the circuit must be reopened for the timer to function.
The push rail does not fully retract or push rail retracts completely and holds but does not open door:
-
Verify mechanical installation and correct as necessary:
- Is excessive force required to depress the push bar?
- Are latches fully clearing the strikes when mechanically cycled?
The push rail retracts and unlocks electrically but does not relock:
- Confirm that the Timer Mode contact is opened (the rail will remain depressed until the contact is opened and the delay has expired).
- Physically disconnect power from rail (while electrically retracted) to verify if the issue is mechanical.
- Check for mechanical interference (e.g., warped door, lack of shims, misalignment of rail, etc.).
- Was a motor kit installed? Verify the rail assembly.
Rail behaves abnormally (multiple cycles, clicking, delayed retraction, etc.):
- If a momentary contact is applied to the timer circuit, adjust the onboard timer to a longer duration.
- Remove end cap from rail and confirm that LED is blinking steadily when power is applied. If not, refer to LED signaling.
For applications using automatic operator(s): Door(s) fail to unlock before doors begin to open:

d Inserting crimped contact/wire assembly into new connector position.
If the M93 COM and M93 N.O. (or M93 N.C.) contact is required for your application, select 2 of the 12 wires that are not being used.
Example: If Timer A (pink wire 26-11), and Timer B (tan wire 26-13) aren't being used, move wire assemblies to M93 COM (pink wire to 26-16) and tan wire to 26-18 for M93 N.O. (or tan wire to 26-20 for M93 N.C.).
- 1. Use small tool with pointed tip to remove pink and tan crimped terminal/wire assemblies from 26 pin connector positions 26-11 and 26-13, as shown in Figure 14.
- 2. Lift up plastic lance, as shown in Figure 14, slowly pull pink and tan crimped terminal/wire assemblies out of connector.
- 3. Refer to Figure 15 and install crimped contact/wire assemblies into the new locations.
- 4. Insert pink wire into 26-16 (M93 COM).
- 5. Insert tan wire into 26-18 for (M93 N.O.), or 26-20 for (M93 N.C.) .
