1. When using any Division 1 speaker or driver unit, the speaker mounting assembly may be used only

to support and orient the speaker. Division 1 fittings must be used for electrical connections.

2. When mounting the GAI-Tronics part # 13306-101 speaker horn in an upright orientation, the 411A

mounting assembly can be used with either the 13310 or 13314 Driver. See Figure 5.
