United Technologies Corp.'s Kidde unit on Wednesday said it's recalling about 452,000 sensor smoke alarms in the U.S. after a manufacturing error may compromise the device's ability to detect smoke and alert consumers.

Another 40,000 defective models are being taken off shelves in Canada. Alarms were being sold for $20 to $40 each, according to the U.S. Consumer Product Safety Commission.

"A yellow cap left on during the manufacturing process can cover one of the two smoke sensors and compromise the smoke alarm's ability to detect smoke, posing a risk of consumers not being alerted to a fire in their home," the commission said in a statement.

Kidde is working with the commission, among other authorities, to recall products and ensure defective smoke alarms are replaced with new models, the company said.
