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 .
