The larger siren assemblies (6 or more speaker cells) may only be mounted onto the pole top
bracket after the pole has been set. Due to their increased mass and size, these assemblies
must be properly supported from the bottom of the assembly while being lifted into position.
DO NOT ATTEMPT TO LIFT THE SIREN ASSEMBLY FROM THE TOP!
1. 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).
2. 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.
3. Install a 7/8" flat washer onto each of the mounting studs.
4. 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.
5. Install a 7/8" flat washer onto each of the mounting studs.
6. Install a 3/4" split lock-washer onto each of the mounting studs.
7. 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.
8. Use the adjustment nuts (indicated in step 2) to adjust the siren assembly until it is
level.
