INTRODUCTION
Maser Ultrasonic Rodent Repeller VHFO Digital USFG 10 is a high frequency random signal generator operating between 2 bands i.e. 20khz to 50khs and 30khz to 60khz.The console consists of a master microcontroller and a dedicated driver for the transducers.
The signals from the microcontroller are fed to the dedicated driver. The dedicated driver distributes these signals to the transducers. The transducers then convert these signals in to high frequency sound waves(well above the 20kz frequency which is the upper limit of the hearing range of humans).The transducers emit intensive sound waves at high decibels(sound pressure) that are audible and painful to rodents but are inaudible and harmless to humans. The rodents usually leave the area being protected by the ultrasound waves immediately and at other times it may take as long as 4 to 6 weeks before there is significant reduction in rodent infestation. They do not get killed. The transducers are quiet. If you cannot hear them, do not think the unit is not working. You cannot hear ultrasound.
Salient Features:
- Can drive up to 20 transducers.
- Can have 5 different values for the wave speed parameter which is an indicator for the number of frequency sweeps per minute. The 5 wave speed values available are 90, 100, 110, 120 and 130.
- It has 2 frequency bands of operation which are pre tuned for 100 different frequencies.
- Band A: Ranges from 20 KHz to 50 KHz and
- Band B: Ranges from 30 KHz to 60 KHz
- Has 2 modes of operation:
- Auto Mode: In this mode the controller will shuffle the wave speed parameter and frequency band parameter randomly
- Manual Mode: In this mode the user will have access to change wave speed and frequency band parameters. The parameters once configured will not shuffle or change randomly in the manual mode.
- Transducer test switch is provided on the front panel. When this switch is pressed all the transducers connected to the controller will start emitting an audible sound.
- Each transducer can cover an area up to 300sq feet in room voids and up to 150 sq feet in ceiling and floor voids.
- Can also be interfaced with Maser StreamE transducers.
- CE certified transformers for power supply.
THE SYSTEM
Maser VHFO Digital USFG 10 is a system of one master controller and accessories that include 20 nos. of VHFO transducers, 300 yards of cables and a power coated MS stand. The master controller is installed in the main control room/ server room and the transducers in the problematic areas i.e. above and below false ceiling and below false flooring.
VHFO Digital USFG 10 needs a power connection of 5 A electrical plug point and comes equipped with a 3 pin power supply cord of 1.5meters.
Maser VHFO Transducers
- Each transducer covers an open area of 300sq.ft. when the average height of the ceiling is 10ft.But if installed in the false ceilings or false floorings, it will cover an approximate area of 150sq.ft.The whole system(12nos.) will accordingly cover an open area of approximately 3,600 sq.ft.And if installed in false ceilings and false floorings, the area covered will be considerable less.
- Each transducer occupies a maximum space of 8 cubic inches and is aesthetically designed to match your décor.
- Being monopolar in nature they can be installed in any sensitive area as there is zero risk of sparking.
- The transducers can withstand high temperatures in the false ceilings and low temperatures in cold storages and air locks.
Stand
- Powder coated MS stand accessory for mounting of the master controller.
Cables
- Standard 2core, flexible (14/40) SWG multistranded or 0.5sq. mm single strand, CT wires of 275 meters for connectivity between the transducers and the master console.
