BRK is the professional-grade brand behind many of the alarms electricians install by default. This hardwired combo unit detects both smoke and carbon monoxide, and it adds one genuinely useful feature: a voice alert that tells you which danger is present. That matters because a beeping alarm doesn’t tell you if you need to evacuate for fire or simply ventilate for CO. The voice cuts through confusion immediately.

The alarm runs on your home’s AC power with a battery backup that keeps it working during outages. It uses an electrochemical CO sensor and a photoelectric smoke sensor, which means fewer false alarms from cooking steam than ionisation-based detectors. The interconnect feature lets you link multiple units so when one alarm triggers, all of them sound. That’s standard for new builds, but this unit is a direct replacement for most existing hardwired setups.

One honest limitation: the voice alert is clear but not adjustable in volume. It’s loud enough for a bedroom, but if you place it near a noisy HVAC vent, you might miss the spoken warning over the siren. The included test button works as expected, and the silence button stops nuisance alarms quickly. For a straightforward, code-friendly upgrade to an existing wired system, this gets the job done without fuss.
