I guess you can call me a newbie, but I accept that as long as I get some help....

I have a VIPER 790XV installed in my '93 Lincoln Town Car...I got the alarm installed at a local shop for the obvious reasons that I could not install it myself.....I do however want to add a lot of features and not spend so much $$$.

I want to add a 520t accessory. This is the backup battery & sensor that sounds the siren when the car's battery is disconnected. 1) Is this hard to add to my current installation of the VIPER 790XV?? 2) Is there any complicated wiring diagram that I need to look at before I take on this job? 3) Does anyone have suggestions or tips on doing this install??

I need all the help I can get, I appreciate it, THANKS.

J.R.

Well depends on how well the shop installed your alarm in the first place. Basicly you just need to find the power source for the alarm, cut it and wire in the battery. The sensor will just plug right into the brain on one side, if you allready have a shock sensor your going have to tie it together, just cut the plug off the battery sesor and tie the wires in to the same color wire on the alarm. Hope that helps.

It shouldn't be all that hard to do. First you would need to find where the power was tagged for the alarm and disconnect it. Then you would hook BUB power isolator ( the clear plastic box with four wires on it) to a constant power source ( it could be the same but then again you have a bub for a reason, for security and if the battery is in an obvious place then what is the purpose). Then you would hook the power output off of the BUB isolator circuit to the power wire off of the alarm. Ground the black wire and hook the blue wire up to the -instant trigger wire ( blue ) from the alarm. I just don't remember off hand which wire colors are for the power supply but the manual should say which. As far as I remember there is not a port on the alarm for this sensor to plug into. Also it is not a multiplexed wire therefore it probably shouldn't be hooked to one of the shock sensors wires (multiplexed inputs)

One more question, once I install the Back Up Battery/Sensor....How do I make sure the siren doesn't go off when I disconnect the battery for some reason, whether it be service/upgrades/ or whatever reason? I there a switch I should install maybe? what do you guys recommend???

Don't disconnect the battery with the alarm armed.

Newer DEI alarms do not go off when first powered up ( but they are armed at that point). But if the alarm is armed when you hook the main battery up it may go off because of the BUB voltage sensing capability and yes you will be able to turn the alarm off with the remote when you reconnect the battery.
