Electric Auto Equalizers
These Auto Equalizer products are an addition to the original pneumatic drive system. People moving through a door can use it as a normal rack & pinion door closer or, at the touch of a button, open the door automatically. An integrated digital control suite provides all electrical control functions. These self-contained units are suitable for use on single leaf doors or pair of doors where each leaf is equipped with an operator. The operator provides all the control and power elements into a single operator package, only some actuators are required to complete the system.
  • Introduced in 1995
  • Two surface mount models available. The 4630 mounts on the pull side of the door and the 4640 series mounts on the push side of the door.
  • Integrates a modified heavy-duty 4040 series cast iron cylinder. The 4040 series closer has been independently tested to 10 million cycles.
  • Mounting plate and cover end caps are only available in a powder coat black finish.
  • 4600 Electric Operators are not approved for smoke

Unique Features

Digital Control Box
Provides exceptionally precise control of a large range of built-in functions combined with superior durability and performance. Visual indications and digital readouts of all control function settings and activity make adjustments easy, fast and accurate.

Dual Independent Program Memories
Each unit is pre-programmed to factory default settings. The installer can adjust the unit to meet the job site requirements. These field settings are locked into the computer’s memory. Any subsequent field adjustments replace the original field adjustments. The factory settings are always retained in memory and can be recalled to replace the field settings in just seconds, restoring the unit to it’s original programming.

On-Board Diagnostics
Sophisticated built-in diagnostics program monitors the system microprocessor, power supplies, drive system and actuators circuitry. Reduces the time required to make sure the installation is complete and correct.

On-Board Power Supply
Provides both 12V DC and 24V DC outputs to power card readers, manual actuators and other peripherals.

“No Destruct” Drive System
Specially designed motor and clutch assembly provide a ‘breakaway’ function that reduces the chance the operator will be damaged in an abusive application. If a vandal tries to force the door closed while it is trying to open, the clutch mechanism prevents damage. The door is never out of control because the heavy duty 4040 closer is always operable.

Electronic Circuit Protection
The high voltage input circuit is protected by an electronic circuit breaker. The low voltage output circuits by self-resetting fuses.

Visual Function Indicators
LED’s allow direct observation of these inputs:
input power

  • fire alarm input
  • normal trigger (actuator) input
  • sequential trigger (actuator) input
  • hold open/alternate action (actuator) input
  • lockout timer
  • safety sensor (clear) input
  • safety sensor (active) input

Programming Mode
Allows tailoring the following functions to meet specific site
conditions:

  • hold open time
  • 90° slow down time
  • one shot input [ON or OFF]
  • Exterior mode [ON or OFF] function to accommodate resistance, like wind gusts, during the opening swing.
  • electric strike delay timer
  • electric strike 3 second power function [ON or OFF]
  • sequential trigger delay timer
  • alternate action timer
  • lockout timer

Standards, Listings & Approvals

  • UL listed for self-closing doors without hold open under “Swinging Door Closers (GVEV)” file R1943.
  • Tested and certified under ANSI Standard A156.19. Refer to Section 2.1 and consult factory for details.
  • ANSI Standard A117.1, Section 4.13.13
  • ADA law, Section 4.13.12.
  • UBC 7.2 (1997) for positive pressure plus UL 10B and UL 10C listing.
  • Wiring is compliant with both UL 325 and the NEC. Separation of high and low voltage.
  • Consult the factory for other listings such as; cUL, Department of Labor and Industry of the Commonwealth of Pennsylvania, The Board of Standards and Appeals of the City of New York, Fire and Panic Safety Standards of the California State Fire Marshal.
  • UL Listed for Fire Rated Door Operators with Automatic Closers, File No. (GUJY)

Warranty
2 year limited warranty. See General Section for complete details.

Maintenance

  • Operators mounted according to the LCN installation instructions require no periodic maintenance or adjustments
  • Monthly, quarterly and annual visual inspections are recommended
  • No service contracts
Below are examples of typical Electric LCN systems. Please consult your local SSC representative or LCN for assistance with specific installations and material requirements.
 
Single Door System
  • An Interior Door
  • No guide rails or safety devices
  • Free Swinging (or Dogged) Door
 
How It Works
Wireless RF actuators with receiver, powered by the Auto Equalizer simplify installation and minimize installation costs. For automatic door operation, touching either actuator signals the receiver and controller module to open the door to 90°. The door is held there until the system times out, then full spring power is applied to reliably close and latch the door. Door opening speed and hold open time are adjustable on the controller. Closing power and speed are adjustable on the cylinder assembly. If not actuated, the Auto Equalizer functions as a full featured door closer.

Vestibule Entry System
  • Exterior & Vestibule doors
  • Sequential Operation
  • No guide rails or safety devices
  • Controlled Access, Free Egress
How It Works
This installation provides both accessibility and security for building occupants. The Auto Equalizer controller module provides both the power and coordination for card reader and electric strike applications. A built-in delay allows the strike to release before the door begins to open. Two interconnected Auto Equalizers provide sequential operation in both directions. Vestibule actuators allow single door ingress/egress from the vestibule as needed. Note: An EL device requires a separate power supply. If not actuated, the Auto Equalizer functions as a full featured door closer.
