TOOLS AND TEST EQUIPMENT

Ordinary mechanics' tools and electrical tools are suitable for

installation of the siren assembly.

No test equipment is required for installation, except that it may be

desirable to have available an AC voltmeter or voltage indicating

device.

WARRANTY AND SERVICE

See separate warranty statement.

SAFETY PRECAUTIONS

LIFTING THE SIREN - Use a lifting device of adequate capacity.

Do not use the eyebolt for lifting if a pole or other mount is attached

GENERAL

To insure satisfactory operation, careful consideration must be given to

each of these factors:

1 - Site selection for optimum signal coverage

2 - Type of mounting

3 - Power supply requirements

4 - Provision for servicing

SITE SELECTION AND TYPES OF MOUNTING

Careful consideration must be given in selecting a site or sites for

installation. Locations should be plotted on local area maps to provide

the desired coverage. Generally, the highest possible site in the

selected area is the best location. This might be a building, tower or a

hill. Do not mount siren too high so that the sound goes over the top of

the area.

In lieu of a suitable existing structure for mounting, a cedar pole

approximately 40-50 feet long and sunk 8 feet deep is a generally

recommended mount. Refer to the illustrated mounting layouts for

details. Any tall building, trees, hills or other obstructions will tend to

create a barrier, which will produce a deadened area behind the

obstruction.

Figures I through 4 and 7 illustrate typical siren mounting

arrangements, which have been used successfully. These are Roof

Mount, Parapet Mount, Chimney Mount, Tower or Tank Mount and

Pole Mount. Figures 5, 6 and 8 show details of suggested supports and

platforms as well as erecting details.

Another general mounting recommendation that may be helpful is the

following: Determine the height of any building or obstruction within

150 feet of the siren. Keep the siren horn at least 5 feet higher than the

to the siren. (See other information on lifting under heading

INSTALLATION.)

ELECTRICAL - During installation, prewire completely before

connecting to power source. Always disconnect from power source

before beginning any service or maintenance procedures.

qualified personnel should open the electrical control panel cabinet.

Refer to wiring diagrams and observe proper wiring procedures

during installation.

TESTING - CAUTION: Wear ear protectors! Anyone on the same

level- as or very close to the siren should wear ear protection during

operational tests. Prolonged exposure can cause ear damage.

INSTALLATION

obstruction for best sound coverage. Remember that a siren

mounted too high will beam the sound over the top of the

required area.

ELECTRICAL POWER REQUIREMENTS

Adequate electrical power must be available at each siren site

(see SPECIFICATIONS for requirements). Local power

companies will charge extra if the siren is located more than 75

feet from the transformer.

Line voltage fluctuations must not exceed ±10 percent

for specified performance (NEMA standard).

PROVISION FOR SERVICING

A convenient means of working on the siren for periodic

servicing must be provided at time of installation. When using a

pole mount, a platform should be constructed at the proper work

level. Refer to Figures 6 and 7 for platform suggestions.

If rungs or steps are provided for climbing up to a platform, it is

advisable to locate the lowest step at least 10 feet above the

ground to minimize the opportunity for vandalism.
