Smoke detectors have exactly one job: alerting people to smoke, thereby letting them know that something is on fire.

Unfortunately, there are some smoke detectors that aren't doing their job. In fact, it's a pretty large batch. According to KCRG, Universal Security Instruments has issued a recall for roughly 180,000 smoke alarms.

In a statement from U.S. Consumer Product Safety Commission (USCPSC), it was revealed that these smoke detectors "have a misaligned internal switch," resulting in the alarms failing to activate properly. The Commission's website reveals that they received 134 reports of failed activations.

Per reports, the recall is for the 10 year battery-operated ionization smoke and fire alarms with model numbers MI3050S and MI3050SB, with date codes between 2015JAN19 through 2016JUL11.

If you're someone who does have a smoke detector from Universal Security Instruments, you are encouraged to check the alarm immediately, and get rid of it if it has not properly activated.
