RESUME

The WS-125 was introduced by Warnsys as a gas powered siren to military bases in stranded spots with no access to electricity. It served as an attack siren to several military bases across the US and Iran, as well as serving some towns as a storm siren.

HISTORY

Warnsys introduced the WS-125 in 1957 for alerting military bases of possible bombing attacks, as well as being used as a storm warning siren in later years. Well advertising and reliable installation services led to over 3,000 military camps purchasing the siren for alerting air raids. In 1959 Warnsys introduced the WS-125E, an electric alternative for small and medium sized towns to be used as a storm warning and fire siren. Before the WS-125E came out, towns used the original gas powered variant for civilian use, however gas powered sirens proved to be impractical for storm warning and most were removed/replaced. One unit is left in Burlington, CO and has been converted to electricity ever since. In 1979, 5 years before the end of production, the final WS-125 variant came out, and was named Warnsys WS-125B. It was a battery backup version of the WS-125E and could still function after loss of power. Unfortunately at the time, towns weren't really considering battery backup, so the WS-125B was a short lived production model and less than 70 units were sold. Due to the global crisis in 1984 Warnsys had to end production of the WS-125 series.

DESIGN

WS-125

This is the standard WS-125 model. It featured a 15 HP forklift engine, belt driven rotator and a 5 port chopper. Due to the engine's high RPM capacity, the WS-125 sounds like 8 port. It featured a 75L gasoline tank, which proved to be not enough for the fuel efficiency, leading to constant refueling. Later models were upgraded to hold 150L of fuel. It featured the iconic "toilet" horn seen on ACA Allertor and B&N Mobil Directo models. This siren had an output of 125 dB @ 100 ft, and had an effective range of 2.7 mi.

WS-125E

Electric version of the siren. It featured a 10 HP AC motor instead of the standard gasoline engine, while keeping the horn from previous model. The belt drive conversion ratio was modified to rotate faster at a slower RPM. This siren has the actual 5 port sound, however it's output was reduced to 122 dB @ 100ft, and it's effective range was reduced to 2.5 mi.

WS-125B

Battery backup version of the siren. It featured the 10 HP motor from the WS-125E, however to allow it to run off batteries, a rectifier and converter were placed at the energy output. These components changed the voltage from 48V AC to 240V DC. A cover was also added to protect the motor components from weathering. While it was more reliable than the WS-125 and WS-125E, it only sold around 50 units.
