B. Unpacking.

After unpacking the Atkinson Dynamics speaker, examine it for damage that may have occurred

in transit. If the equipment has been damaged, do not attempt to install or operate it, and file a

claim immediately with the carrier stating the extent of the damage. Carefully check all

envelopes, shipping labels and tags before removing or destroying them.

C. Mounting.

The selection of the mounting location for the device, its controls, and the routing of the

wiring are to be accomplished under the direction of the facilities and the safety engineer.

1. Model AD-SS-25.

Speaker Model AD-SS-25 is equipped with a serrated swivel mounting bracket with a

locking nut that allows the speaker to be adjusted through an angle of 90

dimensional outline drawing. The speaker mounting bracket is intended to be mounted on

any relatively flat and rigid surface. There are three mounting holes present in the base of

the mount. Hardware for mounting the speaker shall be provided by the installer. Figure 2

shows the rear cover kit. The cover kit is equipped with a 3/8" NPT liquid-tight strain relief.

This strain relief will accommodate cable diameters between 0.18" and 0.31". Securely

attach the cover to the speaker using the provided fasteners.

2. Model AD-SF-25.

Speaker model AD-SF-25 is intended for flush mounting. Figure 3 is a dimensional outline

drawing. There are six mounting holes approximately 0.22" in diameter in its outer flange.

Install the speaker behind a 6-1/8" diameter hole. A small bead of silicone rtv around the

outer flange is recommended when installing this unit into a NEMA 4x rated enclosure.

Hardware for mounting the speaker shall be provided by the installer. Figure 2 shows the

rear cover kit. The cover kit is equipped with a 3/8" NPT liquid-tight strain relief. This

strain relief will accommodate cable diameters between 0.18" and 0.31". Securely attach the

cover to the speaker using the provided fasteners.

3. Models AD-SO-25 and AD-SV-25.

This unit is heavy and should be mounted on a rigid surface capable of supporting the

weight of the speaker.

Speaker models AD-SO-25 and AD-SV-25 are intended to be mounted on any relatively flat

and rigid surface by two mounting ears on the exterior of the housing. Figure 4 is a

dimensional outline drawing showing the proper mounting configuration. The two

mounting ears are 0.41" diameter holes that are spaced 5.68" apart. Hardware for mounting

the speaker shall be provided by the installer.
