Changes to Clocks, Smoke-alarm Batteries

Nova Scotians are reminded to replace the batteries in their smoke alarms when they change the time on their clocks this weekend, Nov. 3 or 4.

"It's a good way to remember an important chore that could save your life," said Robert Cormier, Nova Scotia's fire marshal.

Mr. Cormier recommends replacing the standard nine-volt batteries at least once a year and the fall or spring time change is a good reminder to do so.

When battery power is low, most smoke alarms emit a brief chirping sound. New batteries should be installed in smoke alarms as soon as the old ones are removed.

"It is very important that homeowners replace the battery when they hear that noise, not just remove the battery to stop the chirping, while intending to replace the battery later," said Mr. Cormier. "Removing the battery without replacing it immediately is a risky practice."

The fire marshal's office recommends a smoke alarm be installed on each level of multi-level homes and outside sleeping areas. Alarms should meet the requirements of a professional testing laboratory such as Underwriters Laboratories. They should be tested monthly and replaced every 10 years.
