I have an investment/retirement property in country NSW. The managing agent has the batteries changed when daylight savings starts/stops i.e. twice a year. Only costs me a few dollars and well worth it.
I had more trouble trying to get advise as to where to install them so they were affective but not prone to false alarms. I did call the local fire brigade and ask it they could help but all they could do was to give the same generic advice that the alarm manufacturer supplies.
I'd happily pay to have someone spend 10 minutes telling me the best place to install alarms. Sound like a good opportunity for country brigades to raise some much needed cash.
