Hello all, it has been a while since I've done a alarm install. I apoligise in advice for my newbieish question but.. I recently purchased a Matrix RSX 3.5 and I noticed these new fangled alarm system had three wires for 12V constant. I understand one is for the brain unit and the other is for remote start but whats the 3rd? On my old alarm system where there is only one 12V constant I simply hooked it up to the 12V constant on my vehicle's ignition harness, but hooking up three high current 30A fused on the ignition harness seem to be excessive. Should I run them directly to the battery instead?

iusually run the heavy guages direct to th battery

it is normal to have 3 constant 12v, 2 for remote starter

Why oh Why didn't i take the blue pill

YEAH,i have the same issue.My alarm has 1-20 amp and 1-5amp.My remote starter has 2-30amps and 1-5amp.So it's okay to to run the 1-20 amp and the 2-5amps to the ignition,and the 2-30amps for the remote start directly to the battery??

usually one is for remote start, one for alarm, and one is for the built in relays like park lights etc...

You don't need to go to the battery in most cases. Reality is the remote start is only going to need as much amperage as what the car manufactor gave you at the ignition switch to begin with. Just because the remote start has a few 30a fuses inline doesn't mean it's gonna neeed that much, it's just a maximum the unit will handle. If the cars 12v line to the switch is only rated at 20a, there's no way the remote start is going to need anymore than that(with the exception of light flash).

The reason for multiple 12v lines on your remote start satalite is that some cars have multiple 12v feeds to the switch, and this lets you divide amperage to separate sources just like the car manufactor did.

Hello all.. I have a few pretty straight forward question, I have already searched with no results.

I will be installing my Matrix 3.5 today along with a few accessories; 513t piezo siren, 530t windows module, & 522t trunk popper solenoid. My question is if I need to use a relay to drive these accessories? I read these outputs can only supply a 200mA low current input (i'm not exactly sure how much current ea will be using).. The 513t piezo will be hooked up to the (-) horn output. The 530t windows will be hooked up to (- when alarm is armed) and (-) Channel 6. The 522t trunk will be hooked up to (-) Channel 2.

Now I am certain the trunk solenoid would need a seperate relay (because it is shown on the install guide and mentioned specifically).. but what about the other two accessories/ three outputs?

Also a seperate question about hooking up the piezo to the horn output.. I will program the brain to put out a constant output but will this output chirp the piezo (horn output) when arming/disarming (soft chirp)? because I would like to use a glass break sensor.

use a relay for trunk. diode isolate the GWA to the window module. I like to use a relay for mini piezos to make sure they are nice and loud.

Thanks! So it's not really necesary to use a relay for piezo but recommended right?

Hello

A simple question, is it necessary to use a diode to isolate GWA on newer alarms? I ask this question because it dosen't say anything on the install guide. I just took uninstalled my 10yr old Python 2button alarm system and noticed there were diodes on every GWA trigger, doors, trunk, etc.. is this necessary on newer alarms like the Matrix 3.5 or is it just a extra precaution?
