Motor must produce a door travel speed of not less than two-thirds foot or more than one foot per second without exceeding the rated capacity. Motors must operate on current of the characteristics indicated at not more than 3600 rpm . Single-phase motors must not have commutation or more than one starting contact. Install motors in approved locations.

2.3.2 Controls

Each door motor must have an enclosed, across-the-line type, magnetic reversing contactor, thermal overload and undervoltage protection, solenoid-operated brake, limit switches, and control switches. Locate control switches at least 5 feet above the floor so the operator will have complete visibility of the door at all times. Control equipment must conform to NEMA ICS 1 and NEMA ICS 2 . Control enclosures must be NEMA ICS 6 , Type 12 or Type 4, except that contactor enclosures may be Type 1. Each control switch station must be of the three-button type;
