RAPID RESET OPTION
The new accelerometer switch is a vibration switch calibrated to trip when a lateral impact on the beam
causes a momentary force of acceleration on the bottom beam exceeding 1G. Because of the momentary
nature of this switch, it cannot detect the final condition of the door fabric after impact. Due to the nature
of the mechanical design, it is critical that the door not be electrically operated until the door blade is
completely restored. Failure to reset door fabric back into the tracks will result in considerable damage
to the door blade fabric, and may void warranty.
1. Upon impact, a shock sensor located in the bottom beam will signal the door to stop
immediately. While it is preferable for the driver to stop upon impact, it is not necessary. The
door will not be damaged if the driver continues through the opening.
2. A blinking amber light on the control panel will indicate the door is in need of being reset. A
sticker on the control panel indicates the steps necessary for reset. They are as follows:
• Return the fabric completely onto the side frame guide. This is accomplished by either
moving the bottom bar manually back and forth, or the side frame covers may be opened.
• Push and hold the reset button for 3 seconds until the light goes out. The door is now able
to operate normally.
