Changes to Clocks, Smoke Alarm Batteries

Batteries in smoke detectors should be replaced when the time is changed this weekend (April 1-2).

"Let changing the time on your clock become a reminder to change your smoke alarms' batteries too," said Robert Cormier, Nova Scotia's fire marshal. "It could save your life."

Mr. Cormier recommends replacing the standard nine-volt batteries twice a year, when the time changes in the spring and fall.

"It's a simple, cheap thing to do and it's very important," he said.

When battery power is low, most smoke alarms emit a brief chirping sound.

"Some homeowners may be tempted to remove the battery to stop the chirping, while intending to replace the battery later," said Mr. Cormier. "That's taking a big risk."

New batteries should be installed in smoke alarms as soon as the old ones are removed.

The fire marshal's office recommends a smoke alarm on each level of multi-level homes and outside sleeping areas. All alarms should meet the requirements of a professional testing laboratory, such as Underwriters Laboratories.

Smoke alarms should be tested every month and replaced every 10 years.
