The New Zealand Fire Service believes landlords should be responsible for installing alarms in their properties and ensuring there is a maintenance schedule to regularly check their effectiveness. Most people underestimate the speed of fire. A fire can become unsurvivable in 5 minutes or less.
The Fire Service recommends long-life photoelectric smoke alarms because they offer the best protection for households. There should be a long-life smoke alarm in every bedroom, in the hallway outside bedrooms and other living areas. Even if one alarm fails for whatever reason this level of protection helps provide early warning of fires that otherwise become deadly.
