B.      Door Operator Installation:

Door operators and track arms are to be through-bolted to hollow metal door frame heads and doors (wood or metal) with sex bolts. Heights of frame heads are to be designed to provide a minimum 4-bolt attachment of operator to frame. Refer to door and frame requirements 11.9.5.8 below.

C.      Quality Control:

Installer must be trained and approved by automatic door operator manufacturer for installation and maintenance of product. Include testing and inspection of installation by an inspector certified by the American Association of Automatic Door Manufacturers.

D.      Electric Strike:

An electric strike is necessary to permit the lockset latch to pass through the door frame when the automatic door operator is used, and the lockset lever is not turned. Door sequence of operation must be set to release the strike prior to activation of the door operator to protect the operator motor. Provide fail safe type strike.
