I have a Viper Alarm on my prelude, and I need to install a turbo timer. The shock sensor is triggered by the radiator fan turning on, not to mention the engine running. How is this issue normally taken care of?

Don't alarm the car (just lock it) until the timer is off. That's one way.

I think other TT allow you to connect the alarm wire to the TT, thereby
tricking it into thinking that everything is OK, until the timer shuts off. But
it's probably specific to your timer/car alarm.

 

Hmmm, thats a great idea. I could hook up a relay so that when the car shut off, it re-connected the shock sensor.

I wonder if the alarm would accept the signal of the shock sensor if it suddenly 'sees' it after it arms.

It should work fine.

 

i just wait in the car, or leave the door open and wait till 15 seconds is left, and my car auto alrms after 20 seconds. Done and Done

 

Most alarms cant be armed if the ignition is still on. Try to arm your alarm with the car running.

 

vipers can.

Best bet is to diode isolate your ignition line from the turbo timer to where it wires into the factory ignition line. Then off of the wire going from teh turbo timer to the diode splice in a relay so that the turbo timer ignition line hooks to pin 85, connect 86 to ground, and cut the shock sensor trigger wire (on DEI's it should be the blue line, which is zone 2) and connect one side of the blue wire to pin 30 and the other side to pin 87. This way then the ignition from the turbo timer is active it disrupts the shock sensor trigger wire so it can't go off. When the turbo timer shuts down it will allow the shock sensor trigger wire to function properly again.

You might want to check into using the accessory line(s) instead of the ignition line(s) just because of the amps involved. The accessory line controlled units tend to pull alot less. That or just use a big *** diode

 

What turbo timer and Viper alarm do you have?
