I've read that fire alarm systems need to be replaced on ten year
intervals. I was wondering if all components need to be replaced in
my wireless system. The system includes smoke detection as well
sending alarm to local fire dept.
Included are smoke detector/transmitter, keyboard, and panel. The
system is 12 years old. My initial thought was to replace all the
detector transmitters now. Over the past year two of the detector/
transmitters (I have 4) have malfunctioned. Should I replace the
other components?
