Just installed an alarm at home but think I need a psu. It's got 3 rkp's, 1 bell and about 16 pirs also a wireless receiver. Need help on how to connect a psu.thanks

System make and model, PIR make and model?

Sorry it's a texecom premier 48 elite and pirs are texecom pristige TD and DT.

It sounds overloaded.

Simple as replacing an 8XP for a PSU200XP?

Don't common the positives.

First alarm I've done so don't understand what don't common the positives mean. It's got 2 expanders on already so was just going to put a 2amp psu on.

What are you planning to connect to the 2amp psu? Everuthing else will have the main system battery as backup in mains fail , if psu goes down whatever is on it will go down

Hence as 6w says PSU200XP which has room for batteries, or something similar if you keep ur existing expanders a psu with an alarm output and battery back or something like that perhaps

Yes I was going to get a psu which has battery back up and power both expanders.

Or buy a PSU200 and plug the existing expanders in with the 5-Pin KK crossover connector.
