Hi there,

I have an alarm that has a ground output on arming to trigger central locking. This output stays grounded while the alarm is armed.

My problem is the central locking controler requires a ground input to lock and a ground input to unlock. Is there anyway I can use a relay to make something that could convert the single negative output that would switch over the two central locking inputs?
