The Team at Emalte have extensive past experience, and are currently working on Flood Early Warning Systems for Dams in Indonesia and Australia. The purpose of a Flood Early Warning System for a Dam is to alert decision makers and the public in the event of:
Extra-ordinary rainfall in the catchment resulting in higher than usual inflow into a Dam and river system impacting dam and public safety
Warnings given to the public if unexpected releases necessary for the safety of a dam causing sudden increases in river level downstream
River flows breaking the banks and inundating surrounding areas
Mark Wolf, Emalte CEO believes “The most effective way to warn the public in an emergency is to issue a siren tone followed by a clear and powerful pre-recorded or live P.A. voice message. It is proven that this approach:
ALERT - INFORM - DIRECT,
eliminated confusion, restores order and most importantly, SAVES LIVES!”
Audible tones ALERT the public and gain their attention
Pre-recorded messages INFORM as to the reason for the
ALERT Public Address announcements provide DIRECTION
These same principals, equipment and technology are now being used for warning the Public to other potentially disastrous scenarios:
When lives are on the line only the best will do which is why the warning system pictured is a typical design installed by Emalte, comprising the Whelen WPS2905 complete with solar power and warning lights.
So what makes this a great system:
The sounding radius of this system is a conservative 1.3 kilometers at 70db allowing for 10dB background noise.
Power is deep discharge long life batteries which will maintain operations for up to 7 days without AC power. Modern systems are DC powered so the batteries can be kept charged using solar power or fuel cell power.
The telemetry equipment (installed in the cabinet to the left of the frame) provides the operators with up to date information on the status of the system including: · Amplifier and speaker condition · Power supply (AC ON/OFF) · Low battery voltage · Security
The system can be tested silently either locally or remotely.
