Just been reading some information. It seems there is a requirement for an end of life warning, timer or sealed battery that runs out of power before the end of the cell life. Those requirements, along with the usual, visual and audible alarms.
I am unsure if those new regs apply in all circumstances. My reading so far, seems to suggest that they apply to new
installs of equipment capable of producing CO.
