Heiman Smart Wifi Product

CO is odorless and can strike from any room, every detector in the network must respond the moment danger appears. Wireless Interconnected connects units up to 656 ft (200 m)—when one detects CO, all sound instantly. No Wi-Fi needed, no single point of failure, just whole-home coverage the second it matters. (If you have a Heiman Gateway, you can add to the gateway also；or you have other Heiman interconnected products,suah as S1-R smoke alarm, HS2WL-R water alarm, HS2DS-R door sensor)
【UL 2034 5th & CSFM Certified – Verified, Not Claimed】 Because a CO alarm is only trustworthy if it’s been tested by someone other than the seller, this unit carries UL 2034 5th Edition​ and CSFM​ certification from independent labs. That’s also why it won the Red Dot Award—proving safety and design can both pass the toughest audits. When it sounds, you’ll know it’s real.
【FIGARO TGS5141 – Zero False Alarms, Total Trust】 Because a detector that false-triggers trains you to ignore it, the Japan-made FIGARO TGS5141​ sensor resists humidity, steam, and temperature swings that fool cheaper units. Result: no phantom alerts​ from cooking or showers, with 10 year linear accuracy . When this alarm goes off, there’s actually CO in the air—period.
【Battery & Fireproof – Protection That Doesn’t Quit】 Because CO doesn’t wait for power to return, battery operation (included) means zero downtime—no wiring, no outages, no dead zones. The UL94 V-0​ fire-resistant housing slows flame spread in emergencies. Renters, cabins—anywhere hardwired isn’t an option; this keeps guarding.
【3.5 oz Mini – Small Enough to Install, Loud Enough to Save】 Because the best alarm is the one you’ll actually mount, this 3.5 oz​ low-profile unit tucks into tight bedrooms, hallways, and closets. Screws or magnetic pads—installed in minutes, no tools beyond a screwdriver. One-button Test/Silence, 85 dB, LED indicator. Protection that fits your space instead of fighting it.
