Description

【Gateway + Wireless Interconnect – Home or Away, You're Covered】 Because of CO leaks, whether you're home or not, this 3-pack links to a Smart Gateway that pushes real-time app alerts to your phone—plus all three units sound simultaneously within 656 ft (200 m) so anyone inside hears it instantly. Remote notification + local sound, double the response time. (Works with other Heiman devices like S1-R Smoke alarm, HS2WL-R water alarm,HS2DS-R door sensor)

【App Monitor & Remote Silence – No Ladder Needed】 When a 2 a.m. false alarm shouldn't mean climbing to the ceiling, the HEIMAN app lets you check battery, view alarm logs, and silence nuisance alerts remotely. Cooking fumes triggered it? One tap on your phone and it's muted. Control lives in your pocket, not on a step stool.

【UL 2034 5th & CSFM – Smart Doesn't Mean Cutting Corners】 Connected alarm is still a life-safety device; the core detector carries UL 2034 5th Edition and CSFM certification from independent labs—plus a Red Dot Award for design. Wi-Fi doesn't replace engineering. When it sounds, it's backed by verified standards, not just software.

【FIGARO TGS5141 – False Alarms Are More Dangerous When You're Not Home】 Smart CO detector that cries just gets silenced from the app and ignored; the Japan-made FIGARO TGS5141 resists humidity and steam that trigger cheaper sensors. 10-year accuracy means the only notification you'll dismiss from bed—or from work—is a real one.

【Smart Home Integration & Battery operated – Automation That Stays Online】 CO detector should not only trigger an alarm; the Gateway works with Home Assistant, IFTTT, and SmartThings—auto-ventilate, cut HVAC, or flash lights on alert. Battery-powered with UL94 V-0 fireproof housing, so outages don't blind the system. Three detectors, one gateway, whole-home intelligence.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $16 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for HEIMAN products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
