IMPORTANT NOTE:

MOTORIZED VEHICULAR GARAGE DOORS ARE LIKE A MOVING WALL. THEY CAN BE DANGEROUS & MAY CAUSE SERIOUS INJURY.

IF A GARAGE DOOR IS EQUIPPED WITH AN AUTOMATIC CLOSING MECHANISM SUCH AS AN ELECTRIC OPENER/OPERATOR THEN A SAFETY SENSING DEVICE MUST BE INSTALLED. THIS IS A MANDATORY REQUIREMENT ACCORDING TO CITY OF TORONTO BY-LAW#930-2000 41.a. (other cities have similar by-laws):
“if a garage door allows for vehicular ingress or egress from a parking or storage area, and is equipped with an automatic closing mechanism, the garage door shall be equipped with a sensing device that does not allow the door to close when any person, animal or object is crossing its path”

DUE TO RECENT ACCIDENTS IN THE INDUSTRY, WE STRONGLY RECOMMEND THAT A SAFETY PHOTO EYE SYSTEM BE INSTALLED ON THE INTERIOR & EXTERIOR OF THE DOOR, AS CLOSE AS POSSIBLE TO DOOR IN ORDER TO REDUCE A “DEAD ZONE” AREA. MOREOVER, A SAFETY PHOTO EYE SYSTEM ON OUTSIDE, RE-SETS TIMER & REDUCES LIKELIHOOD OF PEDESTRIANS BEING HIT.

IF GARAGE DOOR IS EQUIPPED WITH AN EXISTING AUTOMATIC CLOSING MECHANISM, WE ADVISE THAT WE CANNOT INSTALL A NEW ELECTRIC OPENER WITHOUT A SAFETY SYSTEM IN PLACE AT THE TIME OF INSTALLATION.
