My alarm has 200ma outputs. But is a 200ma output strong enough to trigger 4 relays? I need to trigger 4 relays at the same time using only one output. Should I be ok connecting the output to 4 relays or will I have to wire up a 5th relay to trigger the other 4? The 5th relay would be the only one triggered by the alarm output, then it would send a ground to the other 4 relays. Has anyone done something like this before?

I'd use the fifth relay. -------------  the12volt • Support the12volt.com

like 12 volt says use one relay to step it up first.
so a total of five relays
so hook up one to be trigger by the 200ma then ground it so it is much higher it will protect your self in the future so you dont blow out that trigger wire.
