Must Hare Authority
To Use Air Raid Sirens
(Coufinued from mage one)


tons snould be of interest TO COM
vices. Mr.. Lee said. Mimeographed
lcopies may be obtained by writing
the state CD office, 65 L. Delaware
Avenue, Newark.
Written authority TO use sirens
in test alerss should be obtained
well enough in advance to permit
notifying the general public ard CD
/ officials concerned.
The new regulations also stress
/ that all radio controlled sirens
must be licensed by the State CD.
/ The license covers the miniature
radio receivers attached to the ST.
rens by which they are tied into
the state system.
According to the regulations. air
raid sirens may be purchased and
| installed for an average of S1540
exclusive of the cost of supporting
structures. Communities, as well as
industrial plants and other organi-
zations wishing to install warning
devices are advised to consult the
new regulations and also to seek
technical advise from the State CD
I
office.
In addition to data on cost, in
stallation, decibel strength and 10
cation of sirens, the new regula-
tions also give a detailed descrip-
tion of the operation of the state
system and explain the new siren
signals adopted about a month ago.
Engineering advice on the pur-
pose and location of a siren is es-
sential if it is to fit into the state
wide sound pattern established by
Civil Defense, Mr.. Lee stressed. He
also pointed ont that some time
ago, the state CD conducted a siren
survey to pinpoint the best location
for sirens in every Delaware COM
munity This information is still
available.
As described in the new regula-
tions. the states air warning sys-
tenn operates this way: A warning
| Of an air attack would come direct
| ly from the Air Force to key con-
| troll point in Dover where operators
are on a 24-hour duty. When he gets
the Air Force warning, the Dover
/ ioperator would simply press two
buttons. These would touch off
every air raid siren which tied into
the state system.
The buttons activate radio trans
mitters which send tone signals to
miniature radio receivers attached
to sirens. Thus, to operate in the
state warning system, a siren must
be equipped with a special receiv-
er, which is maintained and licen-
sed by the state CD.
To insure that communities
without sirens will get the warn
ing, the state CD will furnish one
receiver in each county for the
benefit of the county director.
Warnings received over this can be
famed out" by telephone or
other means to areas not covered by
sirens. However, this method is
cumbersome, and every community
is urged to purchase a siren and
hook 1t into the state system.
The newly adopted siren signals
the "Alert" and the "All Clear"
also are described in the new regu-
lations. The alert, a steady three
to five minute blast, means that the
public should follow the emergency
action plan, such as an evacuation
or mobilization of various units,
set up in advance by local CD au-
thorities. If no such plan has been
prearranged, the public should
await specific instructions from To-
cal authorities.
The Take Cover" wailing tone
or series of short blasts lasting
three minutes-has only one mean
ing: ATTACK is imminent, seek the
best available shelter Immediately"
The former "All Clear" signal has
been eliminated due to the hazards
of radioactive "fallout" which make
it impossible to release the public
from shelters simultaneously. Or
ders to leave shelters will be is
sued locally by means other than
sirens-radio, public address sys
tpnS or. word of mouth
