choose a battery-only smoke alarm such as a 9V or sealed-battery model instead of this hardwired unit

a battery-only model like the kidde i9010 ionization smoke alarm or the kidde 10sdr battery operated smoke alarm fits better

The clear polycarbonate lens carries 3M's premium Scotchgard Anti-Fog Coating

That makes them a purpose-built pick for crews who are already required to wear head protection on a jobsite and need integrated hearing protection rather than a separate over-the-head band fighting the hard hat for space
