The EMS software hasn't changed in a hundred years lol... apart from the SGC software for the Mark 3 panels.
The courses are fine but to be honest they don't tell you half of what you need to know.
The "new head" can come up for all sorts of reasons, generally if you change its sensitivity and put it back, or down powering the device - eg changing batteries, or simply replace the head (the sensing element, not the radio card)... once the devices are logged on initially they are on forever unless you delete them. Changing batteries won't affect that and you don't need to log the device back on again.
The problem is that alkaline devices do not report their battery condition. The length of life left in a battery is determined basically by a countdown timer in the panel, and this timer gets reset to "5 years" ish when the battery info gets to the panel, this can take up to 24 hours as its quite a low priority.
Obviously if a battery fails or nears its lower limits then the panel reports a "Batt A Fail"....
Thanks for this info Dave, I do agree the courses are not enough to know enough... also in your reply there are some things new to me.
Thanks again
