Smoke detector and doorbell wiring questions from Daly City customers
Where are smoke alarms required in a California home?
In each bedroom, outside each sleeping area, and on every level including basements. Carbon monoxide alarms are required in homes with fuel-burning appliances or attached garages.
Why does my video doorbell keep losing power?
Most need 16 to 24 volts, and older doorbell transformers often supply less. Replacing the transformer usually solves it.
Do hardwired smoke alarms still need batteries?
Yes. They have a backup battery so they work during an outage. Newer models use sealed ten-year batteries.
