The Honeywell Home R200H-N1 is a radio-interlinked heat alarm built for rooms where a smoke alarm would create persistent false alerts — kitchens, garages, utility rooms, and boiler cupboards. Rather than reacting to smoke particles, it monitors air temperature and triggers when heat exceeds the rated threshold, making it ideal for environments with cooking fumes, steam, or occasional smoke. Powered by a sealed, tamper-proof 10‑year lithium battery that lasts the full service life of the unit, there is no battery to change — ever. The built-in radio-interlink (RF) module allows seamless wireless interconnection with up to 11 other compatible Honeywell Home R200 series alarms: when one activates, every linked alarm sounds simultaneously, ensuring whole-home awareness no matter where the hazard begins.

⚠ Installation Note: The R200H-N1 contains a permanently sealed, non-replaceable battery and has no user-serviceable parts. Any attempt to open the unit creates a risk of electric shock or malfunction. During building work involving dust or debris, remove the alarm from its bracket or fully cover the vents with brightly coloured tape — and remove the covering each day when work resumes.
⚠ Where Not to Install: Do not position close to air conditioning outlets, fans, or ventilation ducts where draughts could impair detection. The R200H-N1 is designed for rooms prone to dust or cooking fumes; use an optical smoke alarm (R200S-N1) in living areas, hallways, and bedrooms instead.
ℹ Legislation Compliance: The R200H-N1 meets the requirements of the 2022 fire alarm legislation for homes in England, Scotland, and Wales, and is suitable for use as part of a BS 5839-6 Grade F1 interlinked system.
Key Features
Sealed 10-Year Lithium Battery
A tamper-proof, non-replaceable lithium battery powers the alarm for its entire 10-year service life. There is no need for annual battery changes, and the end-of-life signal alerts you when replacement is due — making it ideal for landlords and rental properties where maintenance visits need to be minimised.
Radio Interlink — Up to 12 Alarms
The built-in RF radio module allows wireless interconnection with up to 11 additional compatible Honeywell Home R200 series alarms (smoke, CO, and heat) without any wiring. When one alarm detects a hazard, all linked alarms sound simultaneously, ensuring occupants are warned throughout the entire property.
Heat Sensor — Ideal for Kitchens & Garages
Unlike optical smoke alarms, the R200H-N1 uses a thermistor-based heat sensor that responds to rising temperature rather than airborne particles. This makes it perfectly suited to kitchens, garages, boiler rooms, and utility spaces where cooking fumes or steam would trigger nuisance alarms from a conventional smoke detector.
Alarm Memory & Auto Self-Test
An alarm memory function provides a visual LED indication of any previous alarm activation — useful when the alarm has triggered while nobody was home. The unit also automatically self-tests its sensor and electronics periodically to detect faults, and will indicate any problem with a clearly distinguishable audible fault tone.
Ultra-Slim & Discreet Design
The ultra-slim, compact profile keeps the alarm low-profile on ceiling or wall. The entire front face of the unit acts as a single large test/silence button — no hunting for a small recess button. The 85 dB sounder ensures the alarm can be heard throughout a typical home when activated.
Hush Mode & Do-Not-Disturb
In the event of a non-hazardous false activation, the sounder can be silenced for up to 10 minutes with a single press. Fault tones can be muted for up to 9 hours to avoid nuisance noise while the cause is investigated. A do-not-disturb night mode further reduces unnecessary interruptions overnight.

Frequently Asked Questions
Why choose a heat alarm rather than a smoke alarm for a kitchen?
Optical smoke alarms respond to airborne particles — including cooking smoke, steam, and toast fumes — which frequently causes nuisance alarms in kitchens. The R200H-N1 uses a thermistor heat sensor that only activates when air temperature rises to a dangerous level, eliminating false triggers while still providing reliable fire detection in cooking environments. It is also suitable for garages and boiler rooms for the same reason.
How does radio interlink work — does it need any wiring?
No wiring is needed. The RF radio module built into the R200H-N1 communicates wirelessly with up to 11 other compatible Honeywell Home R200 series alarms (smoke, CO, and heat models). Once paired, if any one alarm detects a hazard, all linked alarms activate simultaneously. This creates a whole-home warning system without the cost and disruption of mains-wired interconnection.
Does the battery really last 10 years without replacement?
Yes. The R200H-N1 uses a sealed, tamper-proof lithium battery pack engineered alongside a low-power electronics chip to sustain the alarm for its entire 10-year rated service life. There is no battery compartment — the battery is permanently integrated. When the unit reaches end of life, it emits a distinct end-of-life warning signal, indicating the whole alarm unit needs replacing. The 10-year battery life is covered by the manufacturer warranty.
Is the R200H-N1 compliant with the 2022 UK legislation for homes?
Yes. The alarm meets the requirements of the 2022 fire alarm legislation applicable to homes in England (Smoke and Carbon Monoxide Alarm Regulations 2022), Scotland (Technical Handbook 2022), and Wales. It is suitable for use as part of a BS 5839-6 Grade F1 interlinked system and is BSI Kitemarked to BS 5446-2:2003.
Can I mix R200H-N1 with R200S-N1 smoke and R200C-N1 CO alarms in the same interlinked system?
Yes. The Honeywell Home R200 series is designed as a unified interconnected family. The R200H-N1 heat alarm, R200S-N1 smoke alarm, and R200C-N1 CO alarm all share the same RF interlink protocol, allowing you to mix and match up to 12 units in a single linked system. This makes it straightforward to build a whole-home Grade F1 system covering every room with the appropriate detector type.
