IWS-IW1 – Police Vehicle Siren

Micro-chip control and steady frequency
Our quality sirens are loud enough to be heard from a considerable distance. For this reason, our sirens are a great choice for law enforcement and first responders alike.
It is important for the first responder community to have the best police siren sounds available.

Just as important, law enforcement officers, firefighters, and EMS workers need to know that their sirens are going to run every time they turn them on.
The 911 Signal model IW1 Siren is a ECO Configuration called the IMPACT siren series.
The siren includes an Amplifier / Relay Unit (IWP) and a microphone (IWM).

The IW 1 Amplifier/Relay Unit housing is NOT waterproof. It must be mounted in a location which is sheltered from falling rain, snow, standing water, etc.
Also, it must be installed in an adequately ventilated area. Never install near heater ducts. Do not mount the IW1 Amplifier/Relay Unit under the vehicle’s hood.
