[Hidden-tech] Fire alarm system

Tue Oct 6 16:03:36 UTC 2020

Thanks for the feedback. All alarms are now replaced. They are no longer
networked and most have 10 year lithium batteries. Only two draw household
current. Previously they were all smoke/CO but that seemed overkill, so we
made 4 smoke/CO that were closest to gas devices and the rest smoke only.
The one in the garage is a replacement heat only.

If all are required to have 10 year batteries, you would think they would
stock only those types at hardware stores, but no. Maybe if they draw
current it's okay to have a replacement battery.

Anyhow, hoping we get 10 years without this hassle.
