Kent FAQ
How old can my smoke alarm be?
Replace smoke alarms every 10 years from the manufacture date printed inside. Older detectors miss real fires and generate false alarms.
Can I disable an alarm that keeps chirping?
No. Replace the battery or the unit. Disabling alarms violates fire code and voids landlord or insurance protections.

Yes. Washington RCW 19.27.530 requires CO alarms outside each sleeping area in homes with attached garages or fuel appliances.
