1. Overview
A. Functions
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.
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.
