I <br />ION <br />Federal's SiraTone system <br />has been developed for <br />applications requiring both <br />siren warning sound and <br />voice communication, and for <br />emergency operation <br />regardless of primary power <br />outages. Its electronically- <br />produced signals are <br />identical to that of a <br />Thunder bolt penetrating <br />electromechanical siren. Two <br />models are available—one <br />omni-directional and one <br />rotating—each capable of <br />producing up to seven <br />different signals plus voice. <br />-s « <br />I *. <br />fe- i; Iv ...-jv' <br />SiraTone Systems <br />The SiraTone system consists <br />of a high pov.cr speaker <br />array, a control/amplifier/ <br />battery cabinet which <br />provides 30 minutes <br />of continuous full signal <br />operation independent of <br />primary power. Activation of <br />both siren sound and public <br />address messages can be by <br />Federal's Siratrol radio <br />control, a pre-installed <br />option (see page 11), by <br />push-button switches <br />connected through landlines, <br />or by direct access. <br />Installation cost is low; no <br />additional electrical services <br />are required. <br />The control cabinet <br />EOWS*C/B contains a <br />diagnostic testing circuit that <br />allows system checkout <br />without alarming the public, <br />a command verification <br />digital counter, signal timer <br />adjustable from two <br />-to five minutes, signal ^ <br />generators, amplifiers, <br />automatic battery charger, <br />optional speaker position <br />control circuitry, and manual <br />siren controls in a NEMA 4 <br />enclosure. It will operate in a <br />temperature range from — <br />•35®Cto +75*>C. ; .V <br />EOWS'LK (Siralok option) <br />is available for DTMF Radio <br />Control Systems to prevent <br />unauthorized activation. <br />This individual DTMF Radio <br />Address will enable cr <br />disable the receivers at <br />each siren site. • <br />Rotating high power speaker <br />models, use highly-reliable <br />.freeze- and rust-resistant <br />mechanisms developed for <br />rotating signs, designed to <br />eliminate rotator damage, <br />and to provide smooth, <br />continuous stall-free rotation <br />and automatic incremental • <br />speaker positioning for PA <br />announcements. They have <br />no dangling interconnect <br />cables. Re-entrant speakers <br />provide maximum protection <br />from the elements for the <br />high-power speaker drivers. <br />Note: Dispersion angles are <br />important when considering <br />rotating sirens. Too narrow a <br />pattern with a high rotational <br />speed may not provide a"" .. j <br />recognizable outdoor J <br />warning signal; listening -..i <br />time is drastically reduced. <br />Greater horizontal dispersion . <br />angles give those alerted <br />more time to hear, interpret, ■: <br />and react to the warning • • <br />signal. ■ •; • ^ <br />. *1 .* I, <br />r <br />• t,’*• .1 f.. <br />a. <br />mI •. »■■{* <br />9 »*- <br />• 4 i *• . .•3 <br />♦ - t-srU V'*, . r-.- • -r--- •. .. .r * <br />1.■■ • • *.•■ /- . <br />-yt rr.- ; <br />e t <br />The entire SiraTone system <br />complies with tough 10 CFR <br />50 quality standards.
