The WPS-2900 siren case assembly may be installed onto the pole and wired before setting
the pole.
NOTE:
Note: Due to the weight of the siren amplifier panel, the electronic cabinet
assembly must be transported in an upright fashion to prevent distortion of
the amplifier panel.
1.
It is necessary for the installer to remember that two factors should determine the
optimum mounting location; the desired distance of the mounted cabinet to the
ground (typically 10 to 12 feet as measured from the bottom of the cabinet) and
available speaker wire length (speaker assemblies are provided with a minimum of
50 feet of speaker wire as measured from the bottom of the speaker assembly).
2.
After the mounting location has been determined, drill an appropriately sized thru-
hole into the pole at the top cabinet mounting hole. Install a bolt loosely into the hole
and hang the cabinet onto the bolt.
3.
With the cabinet fitted snugly to the pole, mark the surface of the pole at the lower
mounting hole location inside the battery storage compartment. Type III cabinets
will have an additional mounting hole located in the second battery storage
compartment (see “Fig. 5: Type III Electronic Cabinet Dimensions” on page 12).
Remove the cabinet from the pole and drill an appropriately sized thru-hole into the
pole at the location(s) marked. Return the cabinet to its mounting location and
secure to the pole using the specified hardware.
4.
Install an aluminum-to-copper lug (crimp or screw style) onto the #4 solid copper
wire. Secure this to the cabinet mounting channel in hole supplied using stainless
steel 1/4 - 20 hardware.
5.
Install the ground rod as specified by local codes and connect both copper wires
(from pole top mounting bracket and electronic cabinet) to this rod.
6.
Install rigid steel conduit and necessary couplings from the speaker’s 1” conduit
adapter to the 1” speaker conduit protruding from the base of the siren case
assembly. Beacon-equipped speakers will require the use of 1.25" speaker conduit
and the necessary adapters for connection to both the 1" speaker base and 1" siren
case assembly.The first section of conduit may be installed onto the speaker’s base
casting prior to mounting the speaker to the pole top bracket. At the option of the
user, conduit unions may be used between the first section of conduit and the speaker
base casting and at the speaker cable conduit entrance to the siren case assembly.
NOTE:
If the location of the conduit on the pole requires difficult conduit bends or
couplings, a section of metal bonded seal tight conduit NOT TO EXCEED 24
INCHES may be used at the top of the pole and/or at the bottom of the pole as
needed for the speaker cable installation.
Batteries for the system should not be installed until the siren station is set in place,
otherwise some leakage of the battery fluid may occur. Batteries should not be connected to
the system until AC power (or solar power if equipped) is available to the system to operate
the system’s battery charger.
