The SonoBlaster!®

‘Dual Alert™’

Work Zone

Intrusion Alarm

The SonoBlaster!® Solution

A New Concept in Work Zone Intrusion Alarms

• Alerts BOTH Workers and Drivers

• Pinpoints the Source of Oncoming Danger

• Provides Multiple Warnings

• Uses No Electrical Power

• As Easy to Deploy as Setting a Traffic Cone

• Light Weight, Economical, Long Life Units

How the SonoBlaster!® Works

• SonoBlaster Alarm Units Mount to Individual Traffic Cones

• Upon Impact, Units ‘Sound-Off’ at Over 125 dB for 15 Seconds

• Each Unit Operates Independently

• Powered by Safe, Reliable CO2 Cartridges

The SonoBlaster!®‘Dual Alert™’• Notifies Workers:

– Provides advance warning to workers allowing them the opportunity to move out of harm’s way.

– The alarm sound pinpoints the source of danger.

• Notifies Drivers:– Each SonoBlaster cone sounds a 125+ dB alarm.

– Alerts drowsing or distracted drivers.

– Drivers can respond by braking or steering out of the work zone – or both.

– Modern cars and SUV’s can stop in 120 to 150 feet.

New Technology

The SonoBlaster!® overcomes

objections found in prior intrusion alarms:• Needs no electrical power to require

maintenance, recharging or ‘go dead’.• Critical unit alignment not required as

with beam or other type devices.• No receiver unit required – each unit operates

independently.• SonoBlaster holds multiple U. S. Patents

Preparing & Cocking the Unit

• Simple Unit Setup Steps:Push the cocking rod into the

end of unit, cocking the unit.Twist-on the CO2 cartridge in

the cartridge holder.

• Visual Status Indication– View the status indicator

through the clear window

Arming the SonoBlaster!®

• Arming the SonoBlaster Unit for Activation:– Lifting the activating arm sets the unit

for action. With the handle lifted, the SonoBlaster alarm will trigger upon tilt or impact.

– Lowering the arm puts the SonoBlaster into ‘Safe Mode’ where it is safe to handle, move, store and nest with other cones.

• Automatic Safety– Nesting a SonoBlaster cone with any other cone

will lower the activating handle and automatically disarm the unit.

SonoBlaster!® Work Zone Deployment

• SonoBlaster units can be deployed and retrieved from a cone truck the same as standard traffic cones.

• The position of the unit’s activating arm near the top of the cone allows a “cone setter” to easily disarm a unit prior to lifting it off the roadway.

SonoBlaster!® Activation

• Shock Activation – The unit fires upon direct vehicle impact.

• Tilt Activation – The unit fires when tilted 90 degrees from vertical.

• Stability – The SonoBlaster is resistant to normal roadway harmonics and vibration.

Typical SonoBlaster!® Layout

• A Typical 100 Yard SonoBlaster Protection Zone.

• Cone Spacing = Approximately 20 Feet Apart.

• Requires only 17 SonoBlaster Equipped Cones.

• Can provide up to 5 seconds or more advance warning - depending on vehicle speeds in the Work Zone.

• Additional time is afforded if errant vehicle driver begins braking.

Combination Layout

• SonoBlaster equipped drums and cones here are used in conjunction with an ongoing line of drums.

SonoBlaster!® Intra-Work Zone Use

• Audibly pinpoints the source of danger.

• Prevents equipment from backing over workers.

• Affords assistance that ‘Back-Up Alarms’ fail to provide.

Accidents Within a Work Zone involving workers injured by their own equipment is a growing problem:

• SonoBlasters define heavy-equipment work boundaries within a work zone separating workers from equipment.

SonoBlaster!® Applications

SonoBlasters work with:• Traffic Cones• Drums• Large Base Delineators• A-Frames • Type III Barricades • Security Fences• Manhole Guards• More...

What Is It for?What Is It for?

• The Wireless Warning Shield (WWS) was created to help prevent injuries and save lives by giving road construction workers as much warning as possible of vehicles encroaching in the “Cone Zone”.

Wireless Warning ShieldWireless Warning Shield

• Vehicle strikes a TCD equipped with the PRT-PRT-300.300.

• A “Radio Chain Reaction”“Radio Chain Reaction” occurs.

• All receivers within range of any PRT-300PRT-300 will sound off.

• Workers react to the danger coming their way.
