Car Alarm: LED Flashes to beat of stereo
I have a Black Widow 1800 Car Alarm installed in my Mazda3. Everything
is stock inside the car. I noticed the other night while sitting in the car and listening to the stereo that the LED was flashing to the beat of the stereo. The heavier the beat, the stronger the flash. I only had the ignition in the ACC position. This problem is not always easy to replicate; however, it shows up most of the time. The car installer said that he's never heard of this problem before. Any thoughts? Thanks Sam |

Car Alarm: LED Flashes to beat of stereo
It may be just your mind playing tricks on you. If you stare at anything
long enough, it will seem to do strange things. If your car alarm has a shock detector attached to it, it may be reacting to the vibrations of the music bass beat.

It sounds like a "feature" not a bug :-)

Any thoughts? Thanks Sam Does it do this with the car running or with the engine off? It may be a low battery and the bass notes are dropping the battery voltage enough to cause the alarm to flash the LED |

Voltage induction. Your LED wire is probably run next to a speaker wire. The
varying voltage from the speaker wire is "inducing" a small amount of voltage onto the LED wire. Do a google search on electro-magnetic induction.

Have you battery tested and if OK, leave it...

Also if this were the case the problem would be more prominent if the engine were on as the amplifier would be receiving more voltage and would have greater headroom. I vote for a big voltage drop at the alarm module causing a hickup that flashes the lamp. Chad |

simple...
the ground or power line for both the alarm and radio are shared...and its too small (cant handle the total load of current) or its week..(bad connection)...

Every time the bass hits, the car voltage drops. the amount of drop depends on how strong the battery is. |

check the wiring for ground and voltage supply
beef it up.. one way of knowing for sur wheres the trouble is to take voltage mesurment while its happening.. those mesurment should be made between the battery ground ant the various point where power pass for the radio and alarm device (but i would highly check at the auxiliary switch of the ignition ;-) ) "Sam" a écrit dans le message de news: nKTcf.477722$oW2.44608@pd7tw1no...

The voltage could drop enough to cause the alarm to think weird things and blink the LED. Even at full output there will be enough voltage to illuminate an LED. The reason it does not dim is because it's probably illuminating at the BOTTOM of the voltage cycle or as the cycle is coming back up. Does the LED flash immediately after you apply power to the alarm system? As for 6 month..... I had the battery replaced on my brand spanking new car within a month of purchase. No system in it. Sometimes you get a bad one. If a battery lasts the first few months it will usually live a normal live barring abuse. The weak ones get weeded out quick Chad |

Maybe the alarm control unit is seeing a low voltage and "turning off" the logic, therefore everytime the voltage drop ends (end of beat impulse) the LED flashes as if the power was re-applied.

Try disconnecting that mounted led at the controller, and hooking up another led at the controller without running the wiring near any other wiring. Doesn't do it anymore, does it? |

Bull****, unless the has both of them wrapped around a ferrite, the LED has WAY too low of an impedance and WAY too high of a forward turn on voltage to even see it. IF it were happening from induction. The LED would only flash at PEAK of ONE EDGE of the WAVEFORM impulse and would have to have a LC CIRCUIT to hold it on to be visible remember it's a damn diode. Wanna do some math? I have wiring all over coming out of amps WAY more powerful than a car amp and have never had induction problems in such confines. Running a 70.7V constant voltage line along a high impedance mic cable for 100' MAY cause induction problems but an LED wire in a dash, get real. It's car audio not broadcast. Try disconnecting that mounted led at the controller, and hooking up another led at the controller without running the wiring near any other wiring. Doesn't do it anymore, does it? 5 bucks says it does. Must be the same brand of LED or with very similar characteristics. I'll Paypal you. Chad |

Just an update to everyone. I did end up leaving the LED/Alarm alone
as some of have suggested. The strobe effect of the LED is caused by the radio/bass vibration affecting the two stage shock sensor. This is normal :-) |
