Hello,

I am using the attached diagram to wire up aftermarket door actuators. Is it ok for the alarms negative triggers to have 12 volts? I think it is but I want to be sure. The alarm will give a ground or negative pulse output to the door lock/unlock wires when they are activated, but is it ok for those wires to have 12 volts on them. The attached diagram energizes the coils on 85 & 86 "red wires" so that the opposite terminals 85 & 86 "green wires & alarms negative triggers" have 12 volts waiting on them. Will this simply be completing the circuit for the relay. I have tested the relay configuration with a simple ground and it works. I just want to make sure that the alarm will not be damaged by attempting to do the same thing.

ThankQ

Darrik

If you are not sure about the wiring, the best thing you can do is test the circuit with low amperage fuses installed on the wires that you think my be problematic. If the system operates properly you shouldn't have any future problems. If you blow a fuse, re-evaluate your wiring.

The wires from the system are suppose to rest at nothing and then when activated, they should be either 12 volts or (-) trigger. You might have a faulty CPU . The best thing to do is ask the dealer where you bought it from and see if this is normal for the units to do this and it not, ask the manuafacturer about this and they should be able to help you on this.
