just bought new alarm for installation. it is to be installed on an old car with no electric windows and no central lock. the difficulty is in wiring the sensors to the alarm brain! it does not have any modules or ports where to wire the trigger from the sensor!! however it does have these connections> door trigger(+) , door trigger (-), cut off port, acc input.

the sensors' triggers connect to any of these?

one other thing... if i buy an alarm brand X, can i wire sensors brand Y to it?

yes most sensors regardless of brand send negative triggers.

use a neg door trigger for the sensors if you using the trigger for more than a couple of sensors use diodes

if its a positive signal from the sensor but they are usually neg.

you can change neg to pos with the help of a relay then use the pos oor trigger
