Installation of Rodent Master Controller & Repellent Transducer in Datacenter

Tuesday, July 8th, 2014

Easy steps to install Varna Suraksha Lxi12 or ZX20 VHFO rodent repellent system within the data-center or hub room to repel rats / mice biting cable or wire.

Place Master Controller within the electrical room or data center where 5 amp power source is available. Proper ventilation is must or temperature controlled room is better.  Stand and bracket will be provided. Master controller to be switched ON 24/7.

The cable between Master controller and Transducers (satellites) should be carefully conduited. Each transducer requires parallel connection from the master console.

Please note: Transducers should be fixed in false ceiling, raised flooring and normal room as well.

Each Transducer can protect upto 300 Sq Ft. in a normal floor, 150 Sq Ft. in false ceiling and false flooring against rats. If there are any obstructions, partitions, sound absorbing material within the room, the area covered will be considerably less, additional transducers has to be installed.

How to fix and focus the Transducer in False Ceiling?

Transducer does not require power. Fix transducer  for every 150 sft area in false ceiling. Face the transducer focusing downwards or even side ways is also fine. (Solid surface is better for maximum bouncing of sound waves.)

Please note: Transducer can be sound tested with help of testing knob provided in the Master console. You will hear continuous beep sound.

How to fix and focus the Transducer in Raised Flooring?

Focus the transducer speaker sideways for maximum coverage. Transducer to be placed for every 150 sft. area.

In the normal room where your servers are installed, you need to place transducers for every 300 sft. area. Do not face the transducers to an open window or door, the sound will escape. If there are any obstructions, partitions, sound absorbing material within the room, the area covered by transducer will be considerably less, additional transducers has to be installed.
