I have to replace a detector on one of these but don't have high enough access on the panel to address it myself so will get it programmed off site. Does a sounder base on this panel share the device address or is it separate? If separate do you get these programmed the same way as a head?
Brand new panel for me, why is there a loop in a repeater, is it a repeater off a loop or a loop off a repeater??
Yeah I need a manual!
