This device is designed for residential use with sectional garage doors that have a torsion shaft and springs. It is not compatible with reverse wound drums, extension springs, outside pickup drums, or low-headroom tracks. The opener supports sectional doors up to 14 feet (4.3 m) high and 18 feet (5.5 m) wide, with 1" diameter torsion bars and torsion springs with 4" to 6" drums.

Function Description:

The Guardian Model 928 is an automatic garage door opener that provides motorized operation for opening and closing sectional garage doors. It incorporates several safety features to prevent injury and ensure proper operation. The system includes a Photo Eye Safety System, a Cable Tension Monitor, and an automatic door lock. The opener can be controlled via a Deluxe Door Control Console (wired) and remote controls. It also features motion-activated security lighting and can be equipped with a battery backup kit for operation during power outages.

  • Torsion Bar: 1" diameter torsion bar.
  • Torsion Springs: 4" to 6" drums.
  • High Lift Doors: Up to 54 inches (137.2 cm) of high lift.
  • Track Radius: 12" or 15" radius tracks.
  • Power Connection: Grounded outlet (120V AC mains). Permanent wiring options available.
  • Door Lock: Automatic door lock (GU-LOCK2) prevents manual operation when closed. Can install a second lock with an extension cable (GU-LOCKX).
  • Cable Tension Monitor (GU-CTM): Detects slack in cables; can be disabled for high lift doors.
  • Battery Backup (B5A928): 12V, 5Ah battery. Mandatory for California SB969 compliance. Provides power during outages, operating the opener at a slower speed. Full charge time is 24 hours.
  • Remote Controls: Up to 20 remote controls can be programmed. Uses CR2032 battery.
  • Photo Eye Safety System: Invisible infrared light beam. Emitter (green LED) and Sensor (red LED) must be aligned. Installed no higher than 6" (15cm) above the floor.
  • Deluxe Door Control Console (3-FDCC): Wired, illuminated console. Installed at a minimum height of 5 feet (1.5m) above the floor.
  • Emergency Release: Manual release cord for disengaging the motor.

Usage Features:

  • Door Control Console: Pressing the "ACTUATOR" button opens/closes the door, stops it during movement.
  • Remote Controls: Wireless operation from up to 100 feet in open field. Requires Photo Eye Safety System to be properly installed and aligned, and vacation lock to be deactivated.
  • Motion Activated Security Lighting: Activated by default, turns on when motion is detected in the garage, remains on for 4.5 minutes. Can be manually activated/deactivated by holding the "LIGHT" button on the console for 2 seconds (1 beep for deactivate, 3 beeps for activate).
  • Vacation Lock: "LOCK" button on the console prevents access via any controls or the door button. "UNLOCK" button restores access.
  • Travel Limit Adjustment: Allows setting the fully-open (UP limit) and fully-closed (DOWN limit) positions.
    • UP Limit: Press "LIMIT" once, then use "UP" or "DOWN" buttons to position the door, then press "LIMIT" again.

  • Auto Force Adjustment: Automatically sets the forces for opening and closing after travel limits are set. Initiated by pressing "FORCE" once.
  • Safety Reverse System: The door must reverse upon contact with a 1-1/2 inch (3.8 cm) high object (or 2x4 board) laid flat on the floor. This test must be performed monthly and after any adjustments.
  • Photo Eye Safety System Operation: If the invisible light beam is obstructed during closing, the door stops and reverses to the open position, and the operator beeps 20 times. The door will not close if the photo eyes are obstructed.
  • Cable Tension Monitor Operation: Detects slack in cables, which may indicate a problem, and triggers a beep (13 beeps).
  • Automatic Door Lock Operation: Prevents manual operation when the door is fully closed. If disconnected or damaged, the opener beeps 7 times.
