Power, Fault, and Alarm Indicators
POWER: GREEN
A steady green light confirms AC power.
During battery backup, the green light flashes every 40 seconds.
FAULT: YELLOW
A yellow light signals low battery, sensor trouble, or end of life.
Voice alerts help identify the issue so you can take action.
ALARM: RED
A flashing red light signals a smoke or CO alarm.
Distinct alarm patterns + voice warnings help identify the danger.
Two Hazards, Distinct Alerts
Smoke uses a three-beep pattern with “Fire!” / “Incendie!” voice alerts. CO uses four quick beeps with “Warning! Carbon Monoxide” / “Attention! monoxyde de carbone!” Treat either signal as an emergency.
Indoor Residential Placement
Install on a ceiling or wall in recommended residential locations, following the manual. Avoid kitchens too close to cooking appliances, bathrooms and other high-humidity areas, strong vents, and locations outside the stated environmental limits.
Follow the manual for suitable indoor residential placement.

GS886A-3RFDT Frequently Asked Questions
How does wireless interconnection work?
GS886A-3RFDT uses 915MHz RF to link up to 18 compatible alarms at a minimum 100 m open-air reference distance. Walls and floors reduce range, so test every unit after pairing.
Does it need electrical wiring?
No. It is powered by a sealed, non-replaceable CR17450 3V lithium battery and requires no AC wiring. Replace the complete alarm 10 years after manufacture.
How do I pair multiple alarms?
Put the first unit into pairing mode, then pair each additional compatible unit one at a time. Pairing mode remains open for 5 minutes. Afterward, test every alarm in the network.
What voice alerts does it provide?
Smoke uses “Fire!” / “Incendie!” with three beeps. CO uses “Warning! Carbon Monoxide” / “Attention! monoxyde de carbone!” with four quick beeps.
How long is the silence period?
Smoke silence is about 8 minutes and CO silence is about 5 minutes. Dense smoke or a real CO condition overrides silence.
Can I use it in an RV or boat?
No. The manual says it is not designed for a recreational vehicle or boat.
Do wireless interconnected alarms meet building code?
Not automatically. Requirements vary and some jurisdictions require hardwired or AC-powered alarms. Confirm requirements with the authority having jurisdiction.
Can cooking smoke trigger it?
Yes. Keep it away from cooking appliances as directed in the manual. After confirming there is no fire, ventilate and use TEST/SILENCE.
What should I do if it alarms?
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.
Can I pair it with any Siterwell wireless alarm?
Pair only models specifically identified as compatible in the current documentation. Do not claim universal brand compatibility.
What standards are listed?
The manual lists UL 217, UL 2034, CAN/ULC S531-19, and CSA 6.19-17. Check the product label and current manual for applicable marks and editions.
What warranty applies?
The manual states a 36-month limited warranty from purchase. See the warranty policy for current coverage and exclusions.
