I installed a Viper 350 Responder (3305V) 2-way car alarm system in my 2000 Subaru Legacy last month. It works great. However, the thieves in my area are particularly stupid. One bashed out my passenger side window last week, then ran away after the shock sensor triggered a Warn Away chirp. I have the Viper stickers on each side of my windows and the blinking blue light on the top and center of my dash. Not sure what he was thinking, maybe that it was a decoy light? Guess he didn't notice my dash cam either, because I caught him on video and got his license plate. =D
Nothing was stolen, and the 2-way key fob woke me up immediately. So I was out there in minutes, which is awesome from a security standpoint. However, replacing a window is still a huge pain. To to prevent future window bashings, clearly I need to install a motion / field disturbance sensor to trigger some type of warning chirp that lets these clowns know that yes, it is in fact a real alarm system. The DEI 508D Field Disturbance sensor seems to be the ticket; my alarm system even has the 4-wire optional sensor connector port, so this sensor would be plug-and-play.
Here is my problem: I don't want my 2-way key fob waking me up with the Warn Away alert every time somebody walks a little too close to my vehicle late at night. I would like to chirp or activate the alarm briefly, even if only for a second, but I don't want a key fob alert if this sensor is activated. My initial idea is to cut the Warn Away wire from the sensor harness and divert it to a relay that would power the alarm, but I am not sure if that would work or not. My question to you fine folks on the forum is "Would that work?"
This sensor has four wires: Red, Black, Blue and Green. Red and black are 12v constant and ground, and I believe blue is full alarm (instant trigger) and green is Warn Away. Correct me if that sounds wrong. I have a relay I am planning to divert the green wire to that would send power to the alarm when the green wire is powered.
Can anyone give me the thumbs up on this plan of action? Thanks!
