SUBJECT:

Radiological Alarm in Platteville, Colorado

Dear Mr. Cook:

In a recent phone conversation with Dr.

Floyd Shoemaker he requested technical information on the subject siren we have installed in Platteville as a backup to the radio alert system.

Rather than furnish a few bits of information I believe it is prudent to furnish all the information. Therefore I have enclosed a copy of I

the Siratone model E0WS manual for your use.

Please call if we can be of further assistance.

1-3. SIGNAL DESCRIPTION.

Model EOWS is capable of produc-ing six standard signals plus one optional signal for a maximum of seven signals.

I A graphic representation of the six standard signals is shown in figure 1-5.

1 As indicated in the figure, three of the six signals are either a wailing, dual-tone signal or a variation of a wailing dual-tone signal. Similarly, the remain-ing three signals are either a steady dual-tone signal or variations of the steady dual-tone signal. In some of the signals, both tones are produced simul-i taneously, while in others tl% tones are present alternately.
