Frequently asked questions

How is the GS886F-H02 powered?

It runs on 120V AC and uses a non-replaceable CR17450 lithium backup battery. The alarm has a 10-year product life from manufacture. The battery is non-replaceable; actual battery life varies with temperature and use.

What happens during a power outage?

When AC power fails, the backup battery can sound the alarm for at least 4 minutes. With a weak battery, the manual says protection may last up to 7 days; a missing battery means the unit cannot operate. These are backup limits, not 7 days of continuous alarm.

How many alarms can the GS886F-H02 interconnect?

Up to 18 alarms total, with a maximum of 12 smoke alarms and 6 non-smoke alarms, on one hardwired system. All units must be on the same AC circuit.

What wiring does the GS886F-H02 use?

It uses a 120V AC quick-connect harness. The manual identifies black as live, white as neutral and red/yellow as interconnect. Use a qualified electrician and follow local electrical code.

What voice alerts does the GS886F-H02 provide?

For smoke, it sounds three long beeps with “Fire!”; for CO, four quick beeps with “Warning! Carbon Monoxide.” The siren is rated at 85 dB at 10 feet. Check the manual for the full signal table.

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 disconnect AC power to stop an alarm.

Can I silence low-battery or fault chirps at night?

Yes. Pressing TEST/SILENCE pauses low-battery and fault chirps for about 10 hours. The warning returns after the silence period, so replace or service the unit rather than relying on repeated silences.

Will cooking smoke set off the GS886F-H02?

It can. The optical smoke sensor responds to smoke particles, but frying or broiling smoke can still trigger it if the unit is too close to the kitchen. Keep it at least 6 feet from cooking appliances. Because the alarms are interconnected, a kitchen nuisance alarm may sound all linked units; press TEST/SILENCE on the initiating unit and ventilate.

What should I do if the GS886F-H02 alarms?

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. All linked units may sound; identify the initiating unit only after responders clear the building.

What certifications does the GS886F-H02 have?

The manual cites UL 217 and UL 2034 and certifies to CAN/ULC S531-19 and CSA 6.19-17. It does not name a certification body in the text; check the label for the mark and edition.

Can I use the GS886F-H02 in an RV or boat?

No. The manual states it is not designed for use in a recreational vehicle or boat. Use it only in ordinary indoor residential locations.

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.

I replaced 3 of 8 GS562A smoke detectors in my home with the 3 GS886F-H02 smoke/CO detectors that I purchased in my latest order. It would have made the job so much easier if the same connector was used by both smoke detectors. Especially, since the wiring is the same on both models. I knew that, going into the smoke detector replacement job. But, I liked the GS562A units so, I wanted to replace 3 of them with the Siterwell smoke/CO detectors.

Ordered 2

Ordered 2. They arrived in a timely manner, and are working normally.

Dead after a year, no support

Bought a house and the seller replaced the smoke detector with this model. About 14 months after, smoke tripped the alarm. However I cannot get it to shut off without removing the power. Upon giving it power again, it constantly alarms. The test button does nothing except go into pairing mode, which it will resume blaring after.

I contacted support with a picture, the model number, purchase date, and symptoms and my situation including I am not the original purchaser. I was asked twice to provide information such as pictures, the model number, and proof of purchase. After repeating myself, I was told they would not honor any warranty claim without proof of purchase. Normally this is fine, but given many smoke detectors maybe purchased by property sellers, I find this unreasonable. Aside from the brain dead support, and lack of an unconditional product warranty for a device that failed one year after, despite being a 10-year product, especially a critical safety device, I give this a one star.
