Warning Siren Specification/Features ALERTRONIC 6000 General: 1. Siren is capable of 125d6 at 100 feet (free field non -reflective measure- ment) per FEMA, Federal Emergency Management Agency CPG1-17, March 1960. 2. Siren is rotational to project beam of sound in a 36V pattern. 3. Siren rotates 3 RPM to provide complete and constant sound pattern (does not oscillate, which causes a lag in the atility of siren to cover areas on a constant pattern). The rotational siren allows for weather vaneing in high wind conditions by means of a torque 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 charging unit which operates off of 120 VAC 60 Hz/230 VAC, 60 Hz with an output of 5 amps maximum. 9. Batteries keep the system operational (providing a minimum of 30 minutes operation after extended periods in the standby mode) up to two weeks after primary (AC) power failure. Controls: 1. Local control of siren activation-onsist of 5 pushbutton commands for man- ual operation of the unit's signals and Public Address (as well as a switch for rotational control). 2. Controls are able to be set so that the siren can be intergrated into a larger system utilizing land line activation or radio control. 3. Amplifiers in conjunction with speaker assembly operate at less than 4.0% distortion at 1 kilohertz at maximum output and less than 11 distortion at 1 watt. 4. Amplifiers are individually fused so that each amplifier is protected in case of malfunction. Amplifier outputs are short circuit protected to pre- vent failure due to shorted speaker drivers.
