Smart Shield Systems
Wireless Carbon Monoxide Detector
The DSC PowerG PG9933 is a professional-grade wireless carbon monoxide (CO) detector for monitored security systems. It uses a sophisticated electrochemical sensor, communicates over PowerG (915 MHz) with 128-bit AES encryption, and provides local 85 dB temporal-4 alarm + flashing LED while also signaling the control panel for alerts and dispatch. A long-life lithium battery (CR123A) delivers typical 5-year life in residential use.
Why Choose This with Smart Shield Systems
- Code-aware placement: we install per the official guide near sleeping areas and on every level for early warning and audibility.

Frequently Asked Questions
The built-in sounder is at least 85 dB at 10 ft and follows the ANSI temporal-4 CO pattern, with matching LED flashes.
Green = normal heartbeat; red = alarm/test; yellow = trouble/low battery/end-of-life (different flash/chirp intervals). We review these with you during install.
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).
No—this model is not “one-go-all-go.” Your security system will still display the CO alarm and notify per programming.
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.
Press Test/Hush to silence for 5 minutes (alarm) or 12 hours (low-battery). We’ll show you the procedure at handoff.
