Zenertek Electrical Engineering are based in Solihull and can provide a qualified electrician within a couple hours. According to the latest set of fire statistics for England the number of fire fatalities in 2010-11 was 321, which is 28% fewer than 10 years previous and 58% fewer than 25 years earlier (Fire Statistics Monitor, April 2010 to March 2011.) During this time the number of households with smoke alarm ownership has increased dramatically, with 9% of households in 1957 and 86% now. These figures illustrate there is no doubt that smoke alarms save lives. A properly installed mains powered (hardwired) smoke alarm can save lives and protect your home.
Since 1992 building regulations have required that at least one smoke alarm, wired directly to the mains, is installed in every new property. These are obviously powered from mains electricity and to prevent problems with loss of power have a battery backup, with the top end of the market including ten year plus rechargeable lithium cells, which provide of 6 months’ cover in the event of mains failure. These lithium cells also don’t work in other appliances so these are unlikely to be removed by tenant.
In terms of installation of a mains powered alarm under no circumstances should you attempt to do this yourself, a qualified electrician should be used in order to connect these to the mains electricity. In comparison, a battery operated alarm can be installed by anybody and the process and cost tends to be cheaper. The battery operated alarms also usually meet standards set by BS 5839 Part 6 (the standard for installing domestic smoke alarms.)
