Frequently Asked Questions

How loud is the alarm and what pattern will I hear?

The built-in sounder is at least 85 dB at 10 ft and follows the ANSI temporal-4 CO pattern, with matching LED flashes.

What do the LEDs and chirps mean?

Green = normal heartbeat; red = alarm/test; yellow = trouble/low battery/end-of-life (different flash/chirp intervals). We review these with you during install.

How long does the battery last?

Real-world life is typically up to ~5 years on a CR123A cell; the manual specifies minimum 1 year (extremes of heat/humidity shorten life).

Do all CO detectors sound together if one trips?

No—this model is not “one-go-all-go.” Your security system will still display the CO alarm and notify per programming.

Is there a replacement or expiration schedule?

Yes—CO sensors expire in 5 years; the expiry date is stamped on the device. Replace before that date—don’t wait for the end-of-life chirp.

Can I hush a nuisance alarm?

Press Test/Hush to silence for 5 minutes (alarm) or 12 hours (low-battery). We’ll show you the procedure at handoff.

Ready to add monitored CO protection?

Smart Shield Systems will place, enroll, and test your PG9933 PowerG CO detector, set up professional monitoring and mobile alerts, and schedule proactive battery/end-of-life reminders—so your family is protected around the clock.
