Frequently asked questions
Does the GS886-H02 detect both smoke and carbon monoxide?
Does the GS886-H02 detect both smoke and carbon monoxide?
Yes. It combines a photoelectric smoke sensor and an electrochemical CO sensor in one unit. The smoke and CO functions have separate alarm patterns and voice messages, so you can tell which hazard triggered the alarm.
Is the GS886-H02 battery replaceable?
Is the GS886-H02 battery replaceable?
No. It uses a sealed, non-replaceable CR17450 3V lithium battery. The alarm has a 10-year product life from manufacture; when it reaches end of life, replace the complete unit rather than opening the battery compartment.
Is the GS886-H02 interconnected or standalone?
Is the GS886-H02 interconnected or standalone?
It is standalone. It does not require interconnect wiring or 915 MHz RF pairing, so it protects the area where it is installed. For whole-home interconnection, choose the GS886A-3RFDT or GS886F-H02.
What voice alerts does the GS886-H02 provide?
What voice alerts does the GS886-H02 provide?
For smoke, it sounds three long beeps with the voice message “Fire!”; for CO, it sounds four quick beeps with “Warning! Carbon Monoxide.” The siren is rated at 85 dB at 10 feet. Check the manual for the complete signal table.
How long can I silence a false alarm?
How long can I silence a false alarm?
Smoke nuisance alarms can be silenced for about 8 minutes; CO alarms for about 5 minutes. Dense smoke or a real CO condition overrides silence. Never remove the unit or disable the alarm to stop a warning.
Where should I install the GS886-H02?
Where should I install the GS886-H02?
Install it on the ceiling or wall in each bedroom, outside each sleeping area and on every level. Keep it at least 6 feet from cooking and heating appliances. Do not use it in an RV or boat. Cooking smoke can still trigger the smoke sensor; ventilate and use TEST/SILENCE for a nuisance alarm.
What should I do if the GS886-H02 alarms?
What should I do if the GS886-H02 alarms?
Listen to the pattern: three long beeps and “Fire!” mean smoke; four quick beeps and “Warning! Carbon Monoxide” mean CO. For smoke, evacuate and call 911. For CO, move everyone outdoors and call 911 from outside; do not re-enter until responders say it is safe. Treat any alarm as real until the source is identified.
What certifications does the GS886-H02 have?
What certifications does the GS886-H02 have?
The manual cites UL 217 and UL 2034 and certifies to CAN/ULC S531-19 and CSA 6.19-17; the label carries the Intertek mark. Check the label and current manual for the exact editions.
Does the GS886-H02 detect CO below 70 ppm?
Does the GS886-H02 detect CO below 70 ppm?
The manual states the alarm has not been investigated for CO detection below 70 ppm. Do not present it as a low-level CO monitor or as medical protection. If you need low-level monitoring, choose a device explicitly rated for that purpose.
What is the difference between the GS886-H02 and GS886-H04?
What is the difference between the GS886-H02 and GS886-H04?
The GS886-H02 is a combination smoke and CO alarm. The GS886-H04 is smoke-only. Both are standalone, 10-year battery models with voice alerts; choose the H02 if you need CO protection too.
What does the warranty cover?
What does the warranty cover?
The manual states a 36-month limited warranty from the date of purchase. It covers material or production defects and excludes normal wear. Keep your receipt for any claim.
