ALERTING COMMUNICATORS OF AM E R ICA. "YOU CAN DEPEND ON US" Our sirens have been in use around the wzirld for more than 40 years. Entire communities depend on reliable A.C.A. siren systems for disaster warn- ing end signaling applications. Every siren is pre -tested and warranted 5y A.C.A. M anufartured by ALERTING COMMUNICATORS OF AMERICA P O BOX 308 • 10255 N ENTE RPRISE OR • MEOUON Vyl 51092 TELEPHONE 1414, 24: 28rjof,� Warning Siren Specification/Features ALERTRONIC 6000 General: 1. Siren is capable of 125dB at 100 feet (f.-ee field non -reflective measure- ment) per FEMA, Federal Emergency Management Agency CPG1-17, March 1980. 2. Siren is rotational to prarject beam of sound in a 360' pattern. 3. Siren rotates 3 RPM to provide complete and constant sound pattern (does not oscillate, which causes a lag in the ability of siren to cover areas on a constant pattern). The rotational siren allows for weather vaneing in high wind conditions by means of a torcue limiter assembly which re- duces tension on internal components. 4. The siren is completely enclosed in color impregnated fiberglass to prevent rusting and painting maintenance. 5. All metal is plated, primed and painted to prevent rusting. 6. The siren is capable of independent operation, off of a self-contained DC power supply. 7. Sirens operate from two 12 VDC rechargeable batteries wired in series for 24 VDC operation. 8. Control is supplied with battery cutarging unit which operates of of 120 VAC 60 Hz/230 VAC, 60 Hz with an output of 5 amps maximum. 9. Batteries keep the system operational (providing a minimim of 30 minutes operation after extended periods in the standby mode) up to two weeks after primary (AC) power failure. Controls• 1. Local contro; of siren activation c'nsist of 5 pushbutton cowhands for man- ual operation of the unit's signals and Public Address (as well as a switch for rotational control). 2. Controls are agile to be set so that the siren can be intergrated into r larger system utilizing land line activation or radio control. 3. A,.plifiers in conjunction with speaker assembly operate at iess than 4.0% distortion at 1 kilohertz at maximum output and less than 1% distortion at 1 watt. 4. ArPlifiers are individually fused so that each amplifier :s protected in case of malfunction. Amplifier outputs are short circuit protected to pre- vent failure due tc shorted s;e!rPr drive . 5. For ease of maintenance and inspection, 3 lighted display is used to iden- tify that each amplification component and associated power source is op- erational and in order. 6. Amplifiers allow for switchinn between HI and Low sound outputs from 1 watt to 100 watts per speaker driver for service and testing purposes. This way, when being tested, the unit does not cause undue alerting of the public. 7. Controls and batteries are housed in lockable NEMA 11/3R rated enclosures, primed and painted to prevent rL:Sting. 8. Rechargeable batteries are housed in a separate enclosure, isolated frolt the siren components. This separate enclosure is vented to prevent fumes from entering into areas of electronic components (rechargeing fumes are corrosive in nature and could have some effEct on sensitive electronic components as well as being explosive if exaosed to opening and closing contactors). Radio Control: 1. From a central point, siren controls are capable of operation via radio by use of a central control encoder connected to a transmitter, which in turn relays activation coecs to the siren location. At the siren location a decoder is interfaced with the siren control. The decoder receives the transmitted code and decodes the message so that the signals and Public Address can be utilized. Note. A.C.A. provides an area inside the NEMA 12 enclosure for radio de- coder application, so that there is no need to install decoder or the pole along side )f the control box. 2. Environmental parameters of the system parts and components are capable of service within the following ranges: Operating Temperature -400 C to 600 C Storage Temperature -650 C to 1250 C Humidity 0 to 95% Siren Installation Feature: 1. For maximum sound dispersion, the siren should be mounted 45 to 50 feet above ground, per FEMA CPG1-17. 2. The siren mounts on top of a pole mour+ for a well balanced installation. It may also be r-of mounted. 3. Speaker banks are completely assembled and incorporate plug-in weatherproof connectors for cabling between the siren and the control unit to eliminate wiring mistakes and to reduce costly installation time. 4. All mounting hardware provided with the siren package including ground- ing rods and ground wire, as well as cable guard. A.C.A.

Wnconahn SUM (A 141242.2&W You will note that any references to sound level measurements in this brochure involve several factors: Sound pressure level: Measured in decibels on the C weighted scale. Free Field: Obstruction free, non -reverberant anechoic chamber. 100': Distance from siren to sound receiver point. On Axis: Sound receiver is at same height as siren speaker in a direct path with the speaker projector. Frequency: The number of sound waves produced per second (cycles) by a sounding body. Decibel: Unit of sound measurement. A change in decibel reading of + 3db results in a 100% increase in sound pressure level. inverse Square Loss (Spherical Divergence): Each time the dis- tance from a sound source is doubled in a free field, a 6 db loss in sound pressure level will result. Whelen High Powered Electronic Sirens have been tested and certified in an anechoic chamber. This measurement has been x- trapolated to a 100' axial measurement, and is confirmed by field testing. Our free field measurements are verifia- ble under similar conditions. No reference to increased sound pressure level (GAIN) as a result of a questionable "ground reflection factor" is included. A siren installed at a standard mounting height from 35' to 60' is unlikely to generate reflections adding to the free field sound level. Such a dependence upon reflection to inflate or adjust the sound level is an unreliable method for use in system planning. Frequency has an effect on the range of a siren: higher frequencies will attenuate or lessen more over distance than sounds pro- duced at lower frequencies and should be a consideration when planning a system. For a guide to planning your outdoor warn- ing system you may refer to a document pre- pared for the Federal Emergency Management Agency (FEMA) entitled "Outdoor Warning Systems Guide" #CPG 1-17. This document reviews the many procedures involved in site selections, sound coverage and system planning. • 0 • COMPARISON OF SOUND LEVEL ATTENUATION 301 25 15io ' ■ ...Conditions■■�0�t© - ... ,'• ■ ���■r� ■ ■ MAN OPAAFEMP.Wan E ■■ .NEAR _d/I'■■ ■ mommas■%i■ME ■ /% %5 �% ■I ONION 1000 2000 3000 DISTANCE (Feet) Siren Frequency dbc (a Attenuation 100' (a 4(XX)' A 500 124 — 8 B 800 124 —10 C 1(XX) 124 —12 1200 124 — 15 1400 124 —17.5 At four thousand feet Siren A is 9.5 db louder ( more than T X)%) than Siren E. Other tuntributing factors of sound attenuation are not considered in this chart. Several other factors include the following: inverse Square Loss (Spherical Divergence•. ) Barrier Effects —Topographical and man made. Ground composition and cover. Wind. By the above chart you will note that the higher frequencies attenuate more at a dis- tance. Any five sirens that generate 124 dbr at different frequencies will not perform equally in sound pressure over extended dis- tances. This should be considered before studying the impact of any other factors which would also apply to each siren. In discussing sound and frequency no attempt is made by Whelen Engineering Company, Incorporated to suggest the area coverage of a siren station to be used in plan- ning a siren system for your community, and no liability is assumed. Many kcal factors, as pre%lously noted, apply. 19 Federal's SiraTone systern has been developed for applications requiring both siren warning sound and voice communication, and for emergency operation regardless of primary power outages. Its electronically - produced s,gna!s are identical to that of a Thin ider bait Ncurtt atrng electromechanical siren. Two models are available one omni-directional and one rotating —each capable of producing up to seven different signals plus voice. SiraTone Systems The SiraTone system consists of a high power speaker array, a control amplifier/ battery cabinet which provides 30 minutes of continuous full signal operation, independent of primary power Activation of EOWS' LK iSiralok option) is available for DTMF Radio Control Systems to prevent unauthorized 3cfiv3tion. This individual DTMF Radio Address will enab!e or disable the receivers at each siren site. both siren sound and oubfic address me7soges can be by Fedwal's Sir3lrui radio control, a pre -installed option (see page 11), by pushbutton switches connected through landlines, or by direct access. Installation cost is low; no adoittonal electrical services are required. The control cabinet EOWS'CiB contains a diagnostic testing circuit that allows system checkout without alarming the public, a command verification digital counter, signal timer adjustable from two to five minutes, signal generators, amplifiers, automatic battery charger, optional speaker position control circuitry, and manual siren controls in a NEMA 4 enclosure. It will operate in a temperature range from -350C to + 75°C. Two maintenance -free lead - calcium deep -cycle, rechargeable batteries are enclosed within a NEMA 3R cabinet. The batteries have a reserve capacity to operate even the largest system a minimum of 30 minutes. • Rotating high ,:c-,,er speaker models, use hrgh!y-reliable freeze- and rust -resistant mechat.+sms developed for rotating signs, designed to eliminate rotator damage, and to provide smooth, continuous stall -free rotation and automatic incremental speaker positioning for PA announcements. They have no dangling interconnect cables. Reentrant speakers provide maximum protection from the elements for the high -power speaker drivers. The entire SiraTone system complies with tough 10 CFR 50 quality standards. It, is preassembled, prewtred and pretested at the plant, shipped ready for installation Hardware is provided for either universal pole -mounting or for flat - surface mounting. Note Dispersion angles are important whe,ii considering rotating sirens. Too narrow a pattern with a hivh rotational speed may not provide a recognizable outdoor warning signal; listening time is drastically reduced. Greater horizontal dispersion zin !es give those alerted more time to hear, interpret, and react to the warning signal. 4 a� •k 'rfy c a 'Ci 4— •. mil•• �... 4 _r♦ Lifting Eyes Aluminum Projector Rotator Assembly - (enclosed) Driver Assembly — - (enclosed) Aluminum Enclosure - NJ VoiceOR 7 Signals plus This rotating directional t siren has a rating of 124 dBC at 100 feet (30.3 meters).

INTEROFFICE MEMO DATE: October 23, 1986 TO: City Administrator Mark Bernhardson FROM: Police Chief Mel Kilbo SUBJECT: Weather Siren Request The City of Orono budgeted $14,000 for a weather siren to be placed in Navarre in 1986, which was the site of a tornado in 1965. The City Council of Spring ^Park has expressed interest in sharing the expense of this siren because its location at the water plant will supply warning services for them. Also, it does fit into the master siren plan for their emergency preparedness plan, as I am the director for both Spring Park and Orono. This price negotiation can take place after Orono Council action. we have received quotes on both mechanical and electronic sirens. See attached sheet of quotes. I am advocating the selection of an electronic siren for several reasons. Electronic sirens require only 110 Volt electrical service to charge 12 volt batteries because they operate off batteries, power outages Co not affect siren operation. Electronic sirens also can be used directionally with a loud speaker for use in spills of hazardous materials or other needed evacuations. I would recommend low quote of Electric Service Co. at 1,11,668.00 for an electronic siren. To: Mary Butler, Mayor Mark E.
