The Watchdog™ blower siren is the future for safe operation of inflatable amusement rides. It is amazing that the inflatable industry has gone without any type of device for monitoring inflation. Watchdog™ will sound an alarm whenever the inflation of the inflatable is interrupted! Common problems such as: extension cords coming undone, circuit breakers popping, mischievous individuals shutting down blowers, even plugs falling-out of the socket will sound the alarm of a 120 decibel siren within seconds! Watchdog™ will soon be the required standard that will make the inflatable business a safer and better-monitored industry for everyone. We are the first company to say that we exclusively use them with every inflatable! Also all of our inflatables are purchased from manufacturers who only sell lead-free products and are made here in the US.
