Warning Siren Specification/Features <br />ALERTRONIC 6000 <br />General: <br />1. <br />'2. <br />3. <br />4. <br />Siren is rotational to project beam of sound in a 36b° pattern. <br />Siren rotates 3 RPM to provide complete and constant sound pattern (does <br />not oscillate, which causes a lag in the ability of siren to cover areat <br />pattern). The rotational siren allows for weather vaneing <br />in high wind conditions by means of a torque limiter assembly which re­ <br />duces tension on internal components. <br />The siren is completely enclosed in color impregnated fiberglass to prevent rusting and painting maintenance. <br />• • <br />5. .All metal is plated, primed and painted to prevent rusting. <br />.6. The siren is capable of independent operation off of a self-contained DC power supply. > <br />operate from two 12 VDC rechargeable batteries wired in series for 24 VDC operation. <br />8. Control is supplied with battery charging unit which operates off of 120 VAC <br />60 Hz/230 VAC, 60 Hz with an output of 5 amps maximum. <br />9. Batteries keep the system operational (providing a minimum of 30 minutes <br />operation after extended periods in the standby mode) up to two weeks <br />• after primary (AC) power failure. <br />Controls: <br />1. Local control of siren activation consist of 5 pushbutton commands for man­ <br />ual operation of the unit's signals and Public Address (as well as a switch <br />for rotational control). <br />2. Controls are able to be set so that the siren can be intergrated into a <br />larger system utilizing land line activation or radio control. <br />3. Amplifiers in conjunction with speaker assembly operate at less than 4.0% <br />distortion at 1 kilohertz at maximum output and less than 1% distortion at 1 watt. <br />4.Amplifiers are individually fused so that each amplifier is protected in <br />case of malfunction. Amplifier outputs are short circuit protected to pre <br />vent failure due to shorted speaker drivers.
