C) Siren Assembly Mounting (5 Or Less Speaker Cells) - Whelen Engineering Company WPS-2900 Series Installation Manual

IMPORTANT! Before proceeding with the speaker installation, it is necessary for the
installer to know the number of speaker cells to be installed on the utility pole. If the
speaker assembly to be installed consists of 5 (five) or less speaker cells, the speaker
assembly may, at the installers discretion, be mounted onto the utility pole before the
pole has been set. Siren assemblies consisting of 6 (six) or more speaker cells require
the utility pole to be set prior to mounting. These larger assemblies also require a special
mounting procedure that must be followed to avoid damaging the assembly. Both
procedures are outlined in the following sections.

c) Siren Assembly Mounting (5 or less speaker cells)...

Hardware required for installation (factory included)....
(8) 3/4"-10 hex head nuts
(8) 7/8" Flat Washers
(4) 3/4" Split Lock Washers
1. Sling or cradle the utility pole in a safe manner so that the pole top is 3 to 4 feet off
the ground. This will allow the speaker assembly to clear the ground when installed.
2. Locate the 4 mounting studs on the bottom of the speaker assembly (see "Fig. 9:
Siren to Pole Top Mounting Bracket (Side View)" on page 20).
3. Thread a 3/4" hex nut onto each of the mounting studs until there is approximately
1" of space between the top of the nuts and the bottom of the siren assembly. This
space will allow the speaker assembly to be leveled once the pole has been set.
4. Install a 7/8" flat washer onto each of the mounting studs.
5. Insert the four mounting studs through the mounting holes on the top of the pole top
bracket. The bottom of the siren assembly should lie flat against the pole top bracket.
6. Install a 7/8" flat washer onto each of the mounting studs.
7. Install a 3/4" split lock-washer onto each of the mounting studs.
8. Thread a 3/4" hex nut onto each of the mounting studs. Tighten this nut firmly to
secure the siren assembly to the pole top bracket.
At this point the pole should now be set. However, the installer may use their own discretion
as to whether to mount the electronic cabinet onto the utility pole before the pole is set.
When the pole has been set, use the adjustment nuts (indicated in step 2) to adjust the siren
assembly until it is level.
