The A.C.A. Hurricane I30 siren is thft most powerful siren manufactured in the United States. The output cf I30 decibels at 100 feet is radiated
through the computar designed horn to an effective 70 DB. range of 65OO feet, thus giving a total circular coverage of 05 square miles p^r
siren unit. (Federal CD Guide, March 196/J Installation of the siren is faciliated through the use of the swing down feature. This feature pernits raising and lowering-of the head and horn assembly for installation or major repairs, often times without the need of an external crane» The self-contained, weatherproof electrical control compartment requires that only two electrical connections be made – the signal source and the mai» power source.

The signal source for initiating oppraiion of the siren can comp from these mechanisms:
1. Direct mechanical switch
2. Telephone relay
3. Radio relay
4. Program timer
5. Any combination of the sbove
A thorough understanding of the controls of the siren is essential for obtaining maximum operational benefits. The simple, well balanced design of the siren, using manv off-the sh^f components, offers an almost maintenance free unit. The*tough, color impregnated fiberglass enclosures completely eliminate the ne«d for costly and troublesome periodic painting. Because of the high dependability of the siren and the usR of off-the shelf Components, repair is kept to a minimum, but should remire become necessary in the future.the manufacturer stands”ready to advise vou’in making repairs.

At all times it should be kept in mind that some servicing Kill be required of the siren after installation. A means of working on the siren should therefore be provided at the time of installation. The most economical, and generally the most useful, provision for working is that of a small platform for the head and horn assembly at the top of the pole on a pole mounted installation (Fig 16) in addition to g platform around the compressor assembly. For a parapet, roof, or water tower installation, a small railing around the platform is an additional safely feature. If rungs or steps are provided for climbing up to a pole mounted siren, a good policy to follow is to have the first rung no closer to the ground” than 10-15 feet in order to hinder attempts at vandalism..

Careful thought must be given to th* area surrounding the installation site. Any buildings, trees, hills, or oth*r obstructions will tend to create a barrier which wil3 produce a deadened arra behind the obstruction. The typp of electrical power available at the installation site must be
understood before the siren is orejea from the manufacturer. The voltage (208, 220, 230, 240, 380, ¿40, 460, ¿80, 550), phase (single or thrpe), transformer bank ampere rating and other loads on that Ixn«, and line frequence (cycles/second) should be tabulated in order to be presented to the manufacturer upon placement of an order. Line voltage must not exceed’ 10< (NEMA standard). Once the phveical barriers around the installation site are mapped and understood/and the electrical po^er is deemed sufficient for the sir*n, the actual type of siren mounting, can be considered…
