Complete Wiring
Confirm equipment compatibility
MEL is compatible with the following equipment (refer to individual instructions as needed):
- PS900-Series power supplies – PS902, PS904, PS906, PS914
- 900-Series option boards – 900-2RS, 900-4R, 900-4RL
Install 900-2RS, 4R, or 4RL option board(s) into power supply WARNING
Fire alarm (FA) option board required if MEL is installed in fire exit hardware.
Notes:
24 VDC output setting required when MEL device connected.
If installing board in location 2 or 3, rotate board 180˚.
Latchbolt retraction of (2) sequenced MEL devices requires more than 1 second to complete.
When powering multiple components, verify that the amperage requirements of all components combined does not exceed the power supply output rating.
Connect input and output wires to option board (2RS shown)
Check operation
- Activate each input and verify all MEL devices operate properly.
- If any device does not operate properly, see next page for troubleshooting.

MEL Troubleshooting

19 If necessary, troubleshoot operation (LED is only visible with the mechanism case removed)

Power at the MEL MEL Response Condition/Solution

24 VDC

| LED – solid green Latchbolt – retracted| Operation normal, latch retracted immediately
---|---|---
LED – solid red after latchbolt attempts to retract multiple times| Latchbolt cannot fully retract mechanically

Remove power. Depress pushbar and make sure latchbolt retracts and extends fully. If necessary, disconnect any vertical rods or mortise lock from device center case, and reapply power. If motor holds, mechanical adjustments may be required per the device instructions.*

LED – flashing green/red

Latchbolt – not retracted

| Excessive tamper (while power applied, the pushpad was pulled out at least 3 times)

Wait 15 seconds and latchbolt will retract again OR remove and reapply power to clear condition.

24 VDC low| LED – flashing green

Latchbolt – retracted

| Voltage low during latchbolt retraction (latchbolt retracts at reduced force)

Wire length is too long, wire gauge is too small, or power supply has poor regulation.

29 VDC or

greater

| LED- flashing red

Latchbolt – will not retract

| Input voltage is too high for proper operation

Wrong power supply, power supply defective.

13 VDC or lower

| Input voltage is too low for proper operation

Wrong power supply, power supply defective or not set to the proper output voltage.

To set, remove AC power from power supply, change power supply setting from 12 to 24 VDC, then reapply AC power and verify proper operation.

0 VDC| LED – off

Latchbolt – not retracted

| No input voltage

Problem with the power supply, control switch, or wiring.
