The answer to this question depends on which Falcon EL device is involved.
The Falcon 24 and 25 Series Devices with the EL option CAN NOT be converted to MEL in the field.
The 24/25 Series MEL Conversion Kits can be used to convert a mechanical device to MEL or to replace an existing MEL24/25 motor.
Therefore a complete new MEL24/25 device would be necessary to replace an existing EL24 or EL25 device.
Note that the MEL option is not available on the 25-M Mortise devices.
The Falcon/Doromatic 1690 or 1790 with the EL option CAN be converted to MEL in the field.
The Falcon MEL Conversion Kit Installation Instructions for the 1690/1790 shows how the EL solenoid in those devices can be replaced by the MEL motor.
