What First Alert does

First Alert is a 60+ year-old US fire-safety brand, founded in 1958 and headquartered in Aurora, Illinois, owned and operated by Resideo Technologies, Inc. It manufactures and distributes a residential safety portfolio of roughly 90 SKUs spanning smoke alarms, carbon monoxide detectors, combination smoke/CO alarms, smart WiFi alarms, home and commercial fire extinguishers, EZ Fire Spray, water leak and freeze detectors, fire escape ladders, and radon test kits. Its proprietary Precision Detection sensing layer uses electrochemical and photoelectric sensors conforming to UL 217 10th Edition and UL 2034 standards, and smart SKUs add WiFi/Z-Wave connectivity, voice/Heads-Up location alerts, interconnect up to 12 detectors, and compatibility with Google Home, Ring, Schlage, Genie, Kwikset, and Resideo's Total Connect 2.0 platform. The First Alert App and a professionally installed, 24/7-monitored home security service (delivered through Resideo's installer network) round out a connected-safety ecosystem built on top of the retail hardware base.

First Alert generates revenue almost entirely through one-time hardware sales priced from roughly $22 (entry CO detector) to $130 (SC5 smart alarm), with a smaller recurring layer from professionally monitored security contracts. Go-to-market is channel-led: products ship through firstalert.com and 12+ national retailers including Lowe's, Amazon, Costco, Target, Best Buy, ACE Hardware, True Value, Do It Best, Fleet Farm, Meijer, BJ's, and Bed Bath & Beyond, augmented by Resideo's independent security installer network for the pro-monitoring line. Customer segments are horizontal — primarily US residential homeowners (with Canada distribution also listed) and a secondary commercial channel for UL-rated extinguishers — and demand is supported by category tailwinds (IMARC projects the global smoke alarm market at $2.50B in 2025 growing to $4.77B by 2034 at 7.4% CAGR). Standalone brand-level revenue is not publicly disclosed, which limits direct triangulation, but the SKU breadth, retail footprint, and parent-company scale imply a meaningful mid-to-upper-hundred-million hardware business.

Direct peers

• Google Nest Protect: Google's Nest Protect is the leading premium smart smoke and CO alarm, integrating natively with Google Home. First Alert positions its SC5 explicitly as a Nest-Protect-compatible replacement, making this a direct product-and-channel peer in the smart-alarm subcategory.
• Kidde: Kidde is the most direct head-to-head competitor to First Alert in residential smoke alarms, carbon monoxide detectors, and combination alarms, and is owned by Carrier Global. Their product portfolios, retail distribution strategy, and target customers are nearly identical.
• BRK Electronics: BRK is part of the same First Alert / Resideo family of brands and sells interconnect-compatible smoke and CO detectors into overlapping retail and professional channels. As a sister brand under common ownership, it is the closest relevant competitive peer by product overlap.

Emerging players

• Siterwell Electronics: Siterwell is an overseas smart-home safety OEM that produces WiFi smoke, CO, and combination alarms for online and retail channels. It is an emerging peer in the entry-level and connected categories where First Alert competes on price.
• X-Sense: X-Sense is a fast-growing direct-to-consumer smart smoke and CO alarm brand with strong Amazon presence. It targets the same residential customers as First Alert on entry-level and mid-tier smart SKUs, putting competitive pricing pressure on First Alert's mass-market tiers.

Broad incumbents

• Ring (Amazon): Ring is an Amazon-owned smart home security platform that First Alert integrates with via Z-Wave Plus smoke/CO alarms. Ring operates more broadly across video doorbells, cameras, and alarms, but overlaps directly in the connected home-safety notification flow.
• Honeywell Home (Resideo): Honeywell Home is a sister brand also under Resideo and overlaps in thermostats, smart home, and connected safety/security. While not a direct smoke-alarm competitor at retail, it competes for the connected home budget and channel attention within the same owner ecosystem.
• SimpliSafe: SimpliSafe is a leading DIY professionally monitored home security system with smoke and CO sensor peripherals. It competes directly with First Alert Professional Home Security for monitored-safety household spend and overlapping smart-home entry points.
• ADT: ADT is the largest professionally installed and monitored home security provider in the US, competing with First Alert Professional in alarm panels, sensors, and 24/7 monitoring services to residential customers.

Regional players

• Notifier (Honeywell): Notifier, part of Honeywell Building Technologies, is a commercial and industrial fire alarm systems brand. It is comparable to First Alert's commercial-grade extinguisher offerings and addresses overlapping regulatory-driven commercial safety customers in the US.
