Universal Security Instruments has recently issued a recall for its Universal Security Instruments 10 year battery-operated ionization smoke and fire alarms, because, according to the CPSC, they can have a misaligned internal switch causing the alarms to not activate properly, posing a risk of failure to alert consumers to a fire.
The recalled products can be identified by the model numbers MI3050S and MI3050SB. They were sold online through specialty wholesalers and others.
