Motorized Electric Latch Retraction-MEL

Featuring 24 and 25 Series exit devices

Overview

Motorized electric latch retraction (MEL) provides energy efficient electronic control of an exit device for an affordable around the door solution. The MEL option is Falcon's® solution of choice for multifamily and commercial real estate facilities where cost competitive electromechanical latch retraction is desired. It is available on Falcon 24 and 25 Series exit devices, except 25-M (mortise).

These devices always provide mechanical egress. Motorized electric latch retraction can be used with credential readers to unlatch doors momentarily for authorized users, or it can be incorporated with systems to retract latches for extended periods of time to allow free entry. This is a convenient alternative to mechanical dogging. Doors with automatic operators also often incorporate exit devices with electric latch retraction.

The MEL option is available on panic and fire rated devices. Because fire exit hardware must be self latching, an automatic fire alarm system must be incorporated to drop power to fire rated MEL devices in case of fire.

The MEL device is compatible with the following equipment: PS900 Series power supplies - PS902, 904, 906, 914; 900 Series Option Boards - 900-2RS, 900-4R and 900-4RL. The power transfer (EPT, electrified hinge, or door loop) is also sold separately. Please refer to Falcon catalog for more information on EPT-2/EPT-10 power transfers, electrified hinges, and PS900 series power supplies.

How to order

• § To order the MEL feature add "MEL" prefix to device designation (example: MEL-25-R-EO). NOTE: Mechanical dogging is not an option with MEL.
• § To order the MEL conversion kit, please specify finish with part number (US3, US4, US10, US26, US26D, US32D, SP28, SP313). MEL conversion kits are only compatible with mechanical Falcon 24 and 25 series exit devices. MEL kits may not be used to convert an EL device.
