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 

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.  Only 
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 

 

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 

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. 
 
 

NOTE 

 

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.
