On Tuesday, Sept. 27 at 10 a.m. in the Council on Aging, come hear Wayland Fire Chief Neil McPherson talk about why all smoke detectors are not created equal. Chief McPherson will discuss what type of smoke and carbon monoxide detectors should be present in your home, how they operate, and what to do when they start beeping or chirping. There will also be time for general questions and answers. Refreshments will be served. Advance registration appreciated, 508-358-2990 or firstname.lastname@example.org.
