HOW DOES CARCAT DUO WORK?

CARCAT Duo is a 2nd generation ultrasonic rat repellent with strobing LED to attack the two most vital auditory and visual senses of the rat. It uses advanced automatic frequency pattern banding technology which ensures that rats do not get immune to the ultrasound and that way protects your car from rats. CARCAT Duo is currently the best solution for rat in car engine problem.

Ultrasound is a spectrum of sound which starts just beyond the human hearing range (20Hz to 20kHz). Certain animals like Rats/bats/dolphins have the ability to detect ultrasound with varying frequency ranges. The rats/rodents are mainly nocturnal and their night vision isn’t as good. They rely on ultrasound for communication (distress signalling/mating calls) and to a certain extent echo location. CARCAT Duo bombards ultrasound waves with unique patterns which disturb and disorient the rat/rodent. The ultrasound intensity is much more intense and deafening than the rat/rodent can tolerate. To add to its woes, these wave patterns interfere with the echo location and cuts out incoming ultrasound signatures of its natural predators like snakes and cats and also other rats and rodents. They are also very territorial creatures and will attack and kill another trespassing rat/rodent. Ultrasound is its sixth sense and blocking that makes it very insecure of its environment.

If CARCAT Duo is installed as per the installation manual the rats/rodents should stop visiting within a week. Rats/rodents are stubbornly territorial and they will resist relocating as long as possible and it is as per the individual rat/rodent’s tolerance limits against CARCAT Duo’s ultrasound bombardment. Tests and customer feedback have shown they leave within a week.

For existing infestation there might be an initial resistance by the rat/rodent to relocate. (Read above question/answer)

  1. It is advised that the car engine bay area be thoroughly cleaned and washed at the garage making sure rat feces and urine traces are removed as far as possible. Rats/rodent like most animals mark and identify their territory with their urine.
  2. Keep checking the engine bay area for feces/urine traces for a few days post installation and clean it immediately. The rat/rodent may not be able to stay too long in the presence of ultrasound bombardment but will try and mark its territory.
  3. For really heavy infestation tobacco pouches can be put at the time of installation for a more immediate two-pronged effects and force the rat/rodent to relocate or find another shelter.
  4. Park the vehicle at a different location for a few days.

CARCAT Duo repels rats/rodents by bombarding ultrasound. It is a very unbearable sound level for them. They may visit or use to escape a prey but will not be able to stay for too long to cause any damage. Even after installation of CARCAT Duo rat repellent, you may see their presence as the car is their house and they will try their best to resist the ultrasound environment, but the high decibel ultrasound will eventually make them stay away from cars. For protecting car from rats, we recommend to keep persisting with CARCAT Duo rat repellent and keep the car cleaned for any feces or urination mark.

WHAT IS THE USE OF WHITE (STROBING) LED?

CARCAT Duo is a leading ultrasound rat/rodent repellent made specifically for cars. The Strobing/Flashing White LED is just like a camera flash which blinks at a high rate and helps in protecting car from rats by causing visual distress and not let the rat settle down.

No, the strobing white LED does not take more current. It takes the current similar to CARCAT – 1st gen.

As such nothing happens to electronics inside as it is meant for auto grade temperatures. But since the white LED is exposed, it may get covered up with mud or dust, in such cases it is recommended to clean the CARCAT Duo rat repellent front grill area once in a while for proper functioning/effectiveness of the white LED on CARCAT Duo.

Installation

CARCAT Duo is intended to be installed in the engine bay (cavity).

Note: CARCAT Duo needs to be installed firmly (eg. to the engine cavity wall) using the screws provided.

Caution: Using cable ties or double-sided tape will drastically reduce the effectiveness. Strong ultrasonic wave fronts are created when unit is installed securely to a firm base, thus providing a hostile environment for rats.

Yes. It doesn’t matter whether your car is front or rear engine, as long as installation is in accordance to as mentioned in the installation manual. For cars having engines at the bottom (eg. Maruti Ecco) installation should be such that dirt does not accumulate on the front grill of CARCAT Duo.

Note: For best results always ensure unit is facing hard metallic/plastic surfaces of which ultrasound waves can reflect (echo). More reflections (echoes) imply more auditory distress to the rat/rodent.

CARCAT Duo has been thoroughly tested on all segments of cars from small cars to SUVs. As such it can be used in vehicles having a 12 to 24VDC electrical system (battery) and an enclosed engine bay area. As long as ultrasound waves can reflect and are not lost into the open it should work. We give no guarantee it will be effective. Try at your own risk.

Caution: CARCAT Duo is intended to be used only with cars. Installing CARCAT Duo in any other vehicle is at users risk and may render the warranty void. (For protection of industrial panels, sensitive electronics of machinery like CNC’c, assembly line panels, vending machines, etc., visit www.gizmocat.in)

CARCAT Duo’s intended use is to protect a car’s engine bay area against rats/rodents. Some customers have reported success against rats/rodents by installing CARCAT Duo inside ATMs and vending machines. As long as it is an enclosed area similar to a car and ultrasound waves can reflect and are not lost into the open it should work. We give no guarantee it will be effective. Try at your own risk.

Caution: CARCAT Duo is intended to be used only with cars. Installing CARCAT Duo in any other vehicle is at users risk and may render the warranty void.

CARCAT Duo is easy to install. A seasoned mechanic should be able to do it in 10-15 minutes.

Note: Due care should be taken for choosing the place of installation beforehand for maximizing the effectiveness of CARCAT Duo. It needs to be installed firmly (eg. to the engine cavity wall) using the screws provided.

Caution: Using cable ties or double-sided tape will drastically reduce the effectiveness. Strong ultrasonic wave fronts are created when unit is installed securely to a firm base, thus providing a hostile environment for rats.

Note: For high-end cars or cars still under warranty, it is advised to get CARCAT Duo installed at the car’s authorised service centre.

Yes. CARCAT Duo comes with screws, fuse and cable ties. All you need is a mechanic to fit it and get it running.

Wiring (to battery terminals)

It is recommended CARCAT Duo loop connectors be directly connected to the battery terminals. For cars wherein battery is not in the engine bay, connect to live terminals that come to the engine bay area.

Note: For high-end cars or cars still under warranty, it is advised to get CARCAT Duo installed at the car’s authorised service centre.

Caution: CARCAT Duo needs to be always powered ‘ON’. Connecting to terminals which give power only when the car is running will render CARCAT Duo useless.

Troubleshooting

The following indicates CARCAT Duo is functioning properly;

  1. Strobe LED blinks (flashes) around every second
  2. Faint but audible BEEPs every 30 seconds

Note: Audible BEEPs may not be heard in a very noisy environment.

The BEEPs may not be audible in a noisy surrounding. Try a quieter location, else unit needs replacement.

If u can hear the audible BEEP, the unit is functionally working and it will still repel rats. If the unit is still under warranty period, you can avail a free replacement.

Get following checked by a car mechanic;

  1. Fuse
  2. Loose connection of connectors
  3. Disconnect the (+) connector and reconnect after one minute

Still not working? Connect with us to get the unit replaced.

Safety

Yes. CARCAT Duo is harmless and inaudible to humans. The ultrasound sound pressure level (SPL) <100dB for CARCAT Duo is much less than the prescribed safety limit or threshold level Values (TLVs) for airborne (non-contact) ultrasound as laid down by;

  1. American Conference of Governmental and Industrial Hygienists (ACGIH)
  2. International Commission on Non Ionizing Radiation Protection (ICNIRP)
  3. World Health Organization (WHO)
  4. Food and Drug Administration (FDA)
  5. Bureau of Radiation and Medical Devices, Canada and many others

Also ultrasound SPL is almost negligible outside the engine cavity or passenger cabin area.

Yes. CARCAT Duo is harmless to pets. Though some pets may be able to hear the lower ranges of ultrasound frequency, they will not be disturbed or harmed inside the passenger cabin. In fact, the ultrasound sound pressure level (SPL) produced by CARCAT Duo will not even harm the rats/rodents only cause auditory distress.

Battery consumption

CARCAT Duo consumes less than 0.7 watts which is much less power than the other always ‘ON’ gadgets like security system, etc. consume. Car batteries use lead acid chemistry which does not have a very long standby time even if they are disconnected, because they self-discharge at a typical rate of 4% to 10% depending on the make, age and use of battery.

A typical 35 Ah small car battery should work for at least a month considering a 4% discharge rate and assuming full charge.

Yes. CARCAT Duo works on your car battery. Similar to a car security system, it cannot protect against rats/rodents if it is not powered.

Humane, Green

No. CARCAT/ultrasound does not kill or harm the rat/rodent. It gives auditory distress which makes your car engine bay less favourable for the rat/rodent to reside or visit.

Warranty
