Model 2001-130 Siren
Available from Audiotech Digital Signal Corportation
The 2001DC is a unique outdoor warning siren - it's a rotating mechanical siren that can operate on batteries. Unlike the Model 2 and the STH10, the 2001DC provides omni-directional warning coverage by rotating the projector horn as it wails. It has a sound output of 128dBC @ 100 feet and an effective range of 5,600 feet, making it the loudest siren we offer. This siren operates either on 120VAC or can run for up to 15 minutes from its batteries in the event of AC power loss. The batteries are always kept charged when AC power is present. In cold climates, the battery heater option is recommended, as the battery temperature must be maintained at -18°C or higher.
