I have an Infinite Prime alarm ( Pro installed 5years ago).
Alarm worked fine till I had to replace batteries in 2 PIRís & a door mag. Also install/reg a Infinite w/less keypad, & a Infinite W/less smoke detector .
All were registered/tested successfully, which pleased me no end , as I am a newbie.
Trouble was, only the control panel speaker would work, & not the wired/wireless siren,
So followed the INF-WES (w/less siren. Itís also wired to 12v transformer) reg instructions, & re-registered the siren. Which worked fine, sound & strobe.
But then when I ran tests in Services(interface, Walk,transmitters) nothing worked, also all the Zones , W/less keypad, & W/less smoke alarm had been de-registered.
I noticed (belated) that at the top of the INF-WES install instructions it says ďdo not install the siren until registration & testing is complete ď
So my question is do I disconnect the backup battery & 12v transformer(so itís not connected to control panel) before re-registering & testing all zones, & devices?
Then re-install & register the siren.
