The alarm is fine. The battery isn't.
Most smoke alarm failures are missing or dead batteries. A sealed ten-year unit or a hardwired, interconnected system takes the human step out.

Three things most people get wrong
Sprinklers rarely fail. Closed valves do.
In NFPA's data, most sprinkler failures were systems that had been shut off before the fire. Inspection to NFPA 25 matters as much as the install.
Sprinkler contractors and inspection schedules →Houses are lost to embers, not walls of flame.
Vents, gutters and the first 1.5 metres around the house decide most outcomes. They are also the cheapest things to fix.

Where we'd start
Six picks across home, business and wildfire. All products and systems →
Illustration Best retrofit, by a distance $
10-Year Sealed Battery Smoke Alarm
Kidde / First Alert · 🇨🇦 🇺🇸
A battery alarm with a lithium cell sealed inside for the unit's full ten-year life. You cannot remove the battery, which is precisely the point: a missing or dead battery is the reason most failed alarms failed.
Smoke & CO alarms Read the pick →
Illustration Buy the big one $
10 lb ABC Fire Extinguisher (garage & deck)
Amerex / Kidde / First Alert · 🇺🇸 🇨🇦
A 10 lb ABC extinguisher gives you 20+ seconds of discharge, versus 8 seconds from a kitchen model. Mount one at the garage door and one by the deck. Choose rechargeable metal-valve units.
Home extinguishers Read the pick →
Required over commercial grease-producing cooking $$$
Commercial Kitchen Hood Wet-Chemical System (UL 300)
Ansul · Amerex · Pyro-Chem · Kidde Fire Systems · 🇨🇦 🇺🇸
A pre-engineered system inside the exhaust hood sprays potassium-based wet chemical onto the appliances, plenum and duct when fire is detected, and shuts off the gas or power to the cooking line. It is required over most grease-producing commercial cooking.
Kitchen suppression Read the pick →
Check this now if your panel still dials over a copper line $
Central Station Monitoring and Alarm Communicators
Telguard · Napco StarLink · 🇨🇦 🇺🇸
A cellular or IP communicator sends alarm, supervisory and trouble signals from the fire panel to a listed monitoring centre, which calls the fire department. Phone companies retiring copper lines is the main issue in this category right now.
Fire alarm & detection Read the pick →
Illustration Budget retrofit $
1/8 in Stainless Steel Ember Mesh
Various · 🇺🇸 🇨🇦
A roll of 1/8 in (3 mm) stainless mesh stapled or screwed over existing vents is the recommended retrofit when replacement isn't practical. Also use it to close gaps under decks and at the base of siding.
Attic, soffit & crawlspace vents Read the pick →
Illustration Best gutter-mount kit $$$
WASP Wildfire Protection Full Kit
WASP Wildfire · 🇨🇦 🇺🇸
Canadian-designed gutter-clip sprinkler heads that install in minutes without tools and run off a standard garden hose. The full kit covers a typical roofline and includes hoses and splitters.
