GS886F-H02 Frequently Asked Questions
How is GS886F-H02 powered?
It uses 120V AC with a non-replaceable CR17450 lithium backup battery. The complete alarm has a 10-year product life from manufacture; actual battery life varies with use and temperature.
What happens in a power outage?
If AC power fails, the backup can sound an alarm for at least 4 minutes. With a weak battery, protection may last up to 7 days; this is not 7 days of continuous alarm. Without a working battery, the unit cannot operate.
How many alarms can interconnect?
Up to 18 alarms total: no more than 12 smoke alarms and 6 non-smoke alarms. All must be supplied from the same AC circuit.
Does CO interconnect to other alarms?
The manual identifies the smoke function as multi-station when interconnected and the CO function as single-station only. Do not claim a CO event triggers the wired network unless current documentation specifically confirms it.
What wiring does it use?
It uses a 120V AC quick-connect harness: black live, white neutral, and red/yellow interconnect. Use a qualified electrician and follow local electrical requirements.
What voice alerts does it provide?
Smoke is three long beeps plus “Fire!”; CO is four quick beeps plus “Warning! Carbon Monoxide.”
How long can I silence an alarm?
A verified nuisance smoke alarm can be silenced for about 8 minutes and CO for about 5 minutes. Dense smoke or a real CO condition overrides silence. Never disconnect AC power to stop an alarm.
Can I silence low-battery or fault chirps at night?
Pressing TEST/SILENCE can pause low-battery and fault chirps for about 10 hours. Service or replace the unit; do not rely on repeated silencing.
Can cooking smoke set it off?
Yes. Follow placement guidance, ventilate cooking smoke, and use TEST/SILENCE only after confirming there is no fire.
What should I do when it alarms?
Treat smoke and CO alarms as emergencies. Get everyone outside, call 911 from a safe location, and do not re-enter until responders say it is safe.
What standards are listed?
The manual cites UL 217, UL 2034, CAN/ULC S531-19, and CSA 6.19-17. Check the current product label for marks and editions.
Can I use it in an RV or boat?
No. The manual states that it is not designed for a recreational vehicle or boat.
What warranty applies?
The manual states a 36-month limited warranty from purchase; see the warranty policy for current terms.
