SUBJ:
OUTDOOR WARNING SIRENS
This memo is to provide information regarding the recommendation that the city
acquire an outdoor warning siren system. In this memo I will address equipment
options; the possibility of phasing installations; and, maintenance issues. I will
ask that the Council authorize me to advertise for bids on the complete siren
package.
BACKGROUND
While a detailed history has been provided (and is available upon your request),
the past decade has provided the City of Chanhassen with an opportunity to
explore our warning system. This has included providing alternatives for our
community as we watched warning technology develop. In 1996, the Public
Safety Commission carefully analyzed information and concurred that a total
emergency warning system should be comprised of three components:
· Personal awareness of changing weather conditions and
use of TV/radio weather broadcasts;
· Individual use of weather alert radios; and,
· Outdoor warning sirens.
This combination provides the community with access to warnings,
acknowledging that rather than one way serving everyone, the three
will serve most.
Outdoor warning sirens are, to a large degree, exactly that: outdoor warning
sirens. While they are intended for warning people that are outside, we know
they will alert some people that are inside buildings, and that people do leave
doors and windows open in order to hear sirens. We have many activities
occurring in our city throughout the summer that would have people away from
TV, AM/FM radios, and weather alert radios. School field trips, softball, soccer,
be GIJ' of Gfl1lhllSsen. A growing community with clean lakes, quality schools, a chamling downtown, thriving businesses, and beautiful parks. A great place to litle, work, and play.

examples.
ANALYSIS
My position regarding sirens remains the same: we need them as an integral part
of the public safety of our community. I think we have explored the other two
components of the warning system enough to acknowledge that expecting the
entire community to be able or willing to utilize TV/radio or weather radios all
the time is not going to happen. We will continue to educate, recommend and
encourage that they do, but at some point certain responsibility does lie with
them. What we as city government can do is to provide the third component of
the overall warning system: outdoor warning sirens.
Two types of sirens are available: electronic and electromechanical. The
difference can be summarized in that the electronic sirens have no moving parts,
while the electromechanical sirens utilize an electric motor to generate the
sound. Both units have pros and cons, but because the electromechanical sirens
are generally cheaper to initially purchase and to maintain, and are most
frequently used in our area, this is the type I am recommending. Furthermore,
sirens can be purchased as AC (alternating current), DC (direct current), or
AC/DC (battery backup) units. The benefit of the AC units is there is no battery
system to maintain; however, the fact that when power goes down, the siren no
longer works is the obvious detriment. We need sirens with battery units that are
kept charged through a trickle-charge system, except for the siren at the fire
station, which can be AC only, operating offthe fire station.emergency generator
should power cease in that area. Sirens in Carver County are radio-controlled
through the Carver County Sheriffs Department Dispatch Center, but can also
be manually activated at each siren.
I am recommending eight (8) radio activated AC/DC/battery backup units
similar to the Federal 2001 depicted in the attached material, and one (1) AC
siren at the fire station. This will permit us to replace the unit on top of the fire
station with a modern unit, which we can obtain some trade-in value for
(approximately $500.00). This siren is over 20 years old and the manufacturer
has since gone out of business, so parts are increasingly difficult to find. The
radio unit was updated a year ago, so that will be used again, saving
approximately $1,500.00 over a new siren. Also, the existing pole should be
adeguate, so it will not need to be replaced. Finally, this particular siren will
only need to be an AC unit because it operates off of the fire station power,
which includes an emergency backup generator, saving another $3,000.00 as
compared to an AC/DC siren. I am also including in the bid specs a remote
encoder to be installed in our fire department's mobile command unit, which
would permit us to activate our sirens should the county dispatch center become

incapacitated. This remote encoder should cost approximately $1,500.00, and
approximately $200.00 to have installed.
No repair agreements should be necessary for years on new units. Eventually we
may wish to consider annual repair agreements, or we may elect to have repairs
made on a parts and labor basis. We will want to enter into an agreement to
have sirens maintained every other year, which I estimate will cost
approximately $6,000.00 every other year. The operating costs on sirens per
month should be very minimal, with the only electricity used being to trickle-
charge the batteries and to test the sirens monthly. (Eden Prairie's monthly
electrical costs are $6.28 per siren per month.)
The City of Eden Prairie utilizes one of their public works employees to limit
repair maintenance needs, checking the sirens on a monthly basis for blown
fuses and to do any work that does not require specially trained technicians. I
have talked with Public Works Director Charles Folch who has agreed to
provide one of his people for this service. We would utilize neighbors and
neighborhood watch groups to monitor the monthly tests.
Regarding when to install sirens, I would recommend the purchase and
installation of all sirens needed to cover all of the city at once. Surely, costs for
everything will increase with time. And by having the entire system installed
and activated at once, we are sure that it will work as a whole. If the money is
available, I would recommend that the entire system be funded and installed
now.
Another issue is siren location. The map that had been distributed reflects
locations where proper power presently exists and where the city would be best
covered with the fewest sirens. I have also indicated neighboring siren
locations, but remind you that proper planning of siren locations anywhere
would go to the border of a city rather than extending beyond the point needed.
That is not to say that under ideal conditions we could not hear these other
sirens, but we cannot depend on them because if they were installed in the
proper locations, their city would be covered, not ours. On the other hand, I can
predict with some certainty that there will be complaints about installation
locations because of either aesthetic or noise reasons. Also it appears that most,
if not all, sirens can be located in parks or the water tower property. The
reasonable position by the city regarding these is that the sirens are being
installed for the greater good, and need to go to locations best suited for their
use.
Please note that nine sirens are being recommended rather than the original
eight. In reviewing site maps, by adding a unit near the new water tower in the
area of Hwys. 41 & 5, the Arboretum area can be covered, and the other siren
locations adjusted enough to fill in the areas that were not within the ideal
coverage areas before. With the additional siren; mobile encoder; and, trade-in
Mayor & City Council
Don Ashworth, City Manager
April 29, 1998

on the existing siren, I am estimating a package installed price of approximately
$140,000.00, plus sales tax.
RECOMMENDATION
It is the recommendation of staff that the City Council authorize the Public
Safety Director to advertise for bids for nine (9) radio controlled
electromechanical sirens to cover the City of Chanhassen with outdoor
warning, including trading in the one existing siren, and including a remote
encoder unit to be installed in a fire department truck, per the attached bid
specifications.
MANAGER'S COMMENTS
I would anticipate that this item will be quite emotional. However, to spend
more money than you have is not being fiscally responsible. This point is made
in recognition of the fact that if we were to use contingency funds to fund five
sirens at a total cost of approximately $80,000, we will have consumed 80% of
the contingency funds established at the first of the year for operating
emergencies during 1998. Leaving $20,000 in contingency is low in light of the
fact that things happen. It has not been that long since we lost an engine in one
of our fire trucks at a cost of approximately $15,000.
Additional points which support phasing the siren purchases over 2-3 years
include:
. Fiscal Responsibility: From a fiscal standpoint, larger purchases should be
phased to lessen the tax burden at anyone time; and
. My review of the coverage map leads me to believe that approximately 90%
of the community would have coverage with five sirens and that 100% of the
community would be covered if the coverage was looked at from a "outdoor
perspective;" and
. The 1998 tornado season will in all likelihood be over before the sirens are
erected.
Should the city council act to agree with my recommendation to authorize the
bidding of five sirens, the council may wish to return this item to the Public
Safety Commission to determine what sirens would be erected and where in
1998. This recommendation should not delay the installation date(s).

mE 2001 OUTDOOR WARNING SIREN
This unique 127db RotatingSiren was developed specifically first as a battery operated 48
VDC unit for users who (1) Required a powerful Warning Siren at locations that did not
have 240/480 V AC Primary Power available...or (2) Users locations with history of
power failures that required battery power either primary or as back up to primary power.
The 200 I Siren is now available in two Models. The 2001DC is powered by four 12 Volt
batteries to supply 48 Volts power. Batteries are monitored and charged at all times by
regulated chargers from either 120 V AC or 240 V AC primary power source. The
2001DC Siren's first purchaser in the World was Fridley, MN and rapidly became the
most popular ever otfered since Federal's Original Thunderbolt, now replaced by the
2001. .
The Model 2001 AC came out in 1991 for users that did not require battery as either
primary power or back up, and operate on 240 V AC Single Phase power. They are
identical except the 2001 AC does not have the battery cabinet or batteries at cost savings.
Some users purchasing 2001 AC Sirens have determined later that battery operation was
important and con~erted to DC operation.
The following two lists of 200 I users begin with Fridley, MN installed in June of 1988.
The first list is 200 I DC users, the second list is 200 I AC users.
Repeat purchasers are indicated with an *. Names and phone numbers of user's
Emergency Managers ~ not shown because they change sometimes, but we will be
happy to furnish current Emergency Manager (or official in charge) of Sirens in their City
names and phone numbers at your request.
