Hi guys,

I was wondering if someone could help me, I have a Pyronix Enforcer V10, and I would like to connect TWO internal Pyronix Sounders to the system but I am unsure how to connect to the internal IO board, or if to connect any resistors?

I do not currecly have any other item connected to the IO board.

I've attached a couple of pictures of the twin alert connections aswell as the IO board in the Enforcer.

Thanks for your help :)

Hi Dave - no, I have not resolved this yet. I had no reply from people and I have not had the time to look at it again yet. Have you found a solution?
Looking at the spec for the Twin Alert and the Enforcer panel, connecting two of these sounders to an Enforcer will overload the control panel, so I'd advise only one sounder is connected.

+12v on Enforcer to +12v on Twin Alert
COMM on Enforcer to -12v on Twin Alert
Bell on Enforcer to BA on Twin Alert

If you wanted to connect the tamper up, wire one of the T terminals on the TA to zone 33, wire the other T terminal to COMM via a 2K2 resistor (3 red bands) and program zone 33 as Tamper.

Hi, yes I got a simular answer saying only one Twin Alert could be connected, which in my case was fine. Same connections as stated here. Thanks everyone for your help.
