Sec. 8. (a) A supplier who installs, services, or repairs an automatic garage door opening system in a residential building shall conduct an onsite reversal test of the system.  In order to pass the onsite reversal test, the system must reverse the door upon contact with a rigid two inch (2″) high obstacle (or a 2 by 4 block of wood) placed on the surface beneath the garage door.

(b) If the automatic garage door opening system does not pass the onsite reversal test required by subsection (a), the supplier conducting the test shall complete and conspicuously attach to the automatic garage door opening system a label or tag that contains the following information (The following language complies with this requirement, but other language may be used that conveys the equivalent information.):

This garage door opener was tested and does not meet the current requirements for a working safety reverse feature.  This can be dangerous and may cause serious injury or death.  You are advised to disconnect the opener from the door immediately and operate the door manually until the opener has been repaired or replaced with an opener that meets current safety standards relating to automatic reversal.

(c) The word “WARNING” on the label or tag described in subsection (b) shall be in the foreground and background colors that comply with the standards of the American National Standards Institute (ANSI) that are in effect at the time that the label or tag is affixed.

(d) The employer of the person who attaches a label or tag under subsection (b) shall notify the occupant of the residence within ten (10) working days in writing that the residence's automatic garage door opening system does not comply with this chapter.
