About CatSiren
When armed, the CatSiren continuously monitors the motion around your catalytic converter using Doppler Radar technology. If a thief attempts to crawl under your car to saw off your catalytic converter, the CatSiren creates a 130 decibel alarm noise. To prevent false alarms from pets, pests and debris, the CatSiren emits a brief warning signal before activating the full alarm sequence.
The CatSiren is controlled in a convenient and familiar way. When leaving your car, arm your CatSiren with the included remote control. When you return, disarm the CatSiren with the remote control. Sleep easy knowing that no one is attempting to steal your catalytic converter.
Instructions
Identify vehicle catalytic converter. The catalytic converter is located on the vehicle exhaust system between the engine and the muffler.
Having located the catalytic converter, attach the CatSiren to the nearest flat, obstruction-free area of the underside of the vehicle. CatSiren should be mounted 6-8 inches away from the catalytic converter and exhaust pipe to prevent device overheating.
Once the alarm has been mounted, arm the device by pressing the Arm button on the wireless remote.
Before driving, disarm the alarm by pressing the Disarm button.
