The Honeywell Home R200S-N1 is a radio-interlinked optical smoke alarm combining a sealed 10-year lithium battery with a built-in RF wireless interlink module — the key upgrade over the stand-alone R200S-1. Once paired with other compatible Honeywell Home R200 series alarms, a hazard detected by any single unit triggers all connected alarms simultaneously, creating a fully synchronised warning system across your entire property without a single cable. With coverage for up to 12 alarms in one network (including smoke, heat, and CO models), the R200S-N1 is the foundation of a compliant BS 5839-6 Grade F1 interlinked fire and CO system. It meets the 2022 England, Scotland, and Wales fire alarm legislation for homes and carries BSI Kitemark certification to EN 14604:2005.

ℹ Legislation & Standards: Suitable for use as part of a BS 5839-6 Grade F1 interlinked system. Meets the requirements of the 2022 fire alarm legislation for homes in England, Scotland, and Wales. BSI Kitemarked to EN 14604:2005+AC:2008, CE and UKCA marked.
⚠ Not for Kitchens or Garages: Do not install optical smoke alarms in areas where cooking fumes, steam, or vehicle exhaust are regularly present. For these locations, use the Honeywell Home R200H-N1 heat alarm, which is fully compatible with the R200S-N1 in the same interlinked network.
Key Features
Radio Interlink — Up to 12 Alarms, No Wiring
The built-in RF radio interlink module connects wirelessly with up to 11 additional compatible Honeywell Home R200 series alarms — mix smoke, heat, and CO units freely. When any alarm in the network triggers, all connected alarms sound simultaneously, ensuring occupants on every floor and in every room receive the warning immediately.
Optical Smoke Sensor — Smouldering Fire Detection
The optical (photoelectric) sensor detects the large smoke particles produced by slow-smouldering fires — the most common type in domestic settings (burning upholstery, overheating electrical equipment). This sensor type produces fewer nuisance alarms than ionisation types and is the preferred choice for living rooms, bedrooms, hallways, and landings.
Sealed 10-Year Lithium Battery
The tamper-proof, sealed-for-life lithium battery powers the alarm for the entire 10-year service life, assisted by a low-power standby chip. There are no battery changes required, and the alarm signals end of life with a distinct tone. The tamper-proof design also satisfies landlord compliance requirements under current UK legislation.
Auto Self-Test & Clear Fault Indication
The R200S-N1 automatically self-tests its sensor and electronics periodically, without user action. Any identified fault is clearly indicated by a distinguishable audible fault tone separate from the alarm tone. Fault tones can be silenced for up to 9 hours while investigating and resolving the issue, reducing nuisance noise.
85 dB Sounder & 10-Minute Hush
A high-output 85 dB sounder ensures the alarm signal is audible throughout the property. The 10-minute hush function — activated by pressing anywhere on the front face — silences the sounder without disabling detection, allowing time for non-hazardous smoke to disperse. Detection continues throughout the hush period.
Ultra-Slim, Discreet Profile
The ultra-slim body sits close to the ceiling surface, minimising visual impact. The large front face also serves as the test/silence button, making routine weekly testing straightforward. Compatible with the full Honeywell Home R200 range for a unified, consistent appearance throughout the property when mixing alarm types.

Frequently Asked Questions
What is the difference between the R200S-1 and the R200S-N1?
Both models share the same optical sensor, sealed 10-year battery, 85 dB sounder, and ultra-slim design. The key difference is that the R200S-N1 includes a built-in RF radio interlink module, allowing it to be wirelessly paired with up to 11 other compatible R200 series alarms. The R200S-1 is stand-alone and does not interlink. If you need a whole-home system where all alarms sound together, choose the R200S-N1.
Can I mix R200S-N1 smoke alarms with R200H-N1 heat alarms and R200C-N1 CO alarms in one system?
Yes. The Honeywell Home R200 series is a unified interlinked family. The R200S-N1 (smoke), R200H-N1 (heat), and R200C-N1 (CO) all use the same RF interlink protocol and can be mixed in a single network of up to 12 units. This allows you to install the most appropriate detector type for each location — smoke alarms in living areas and bedrooms, heat alarms in kitchens, and CO alarms near fuel-burning appliances — all connected as one system.
How do I interconnect multiple R200S-N1 alarms?
Interconnection is straightforward and requires no tools or specialist knowledge. Each alarm is paired wirelessly using a simple button sequence described in the installation manual. Once paired, the alarms remain linked and communicate automatically — there is no hub, bridge, or app required. The interlink operates on a dedicated radio frequency, separate from Wi-Fi or Bluetooth, for reliable, independent operation.
Does this alarm meet the Scottish Government's fire alarm requirements?
Yes. Since February 2022, Scotland requires all homes to have interlinked smoke and heat alarms — and the R200S-N1 is specifically designed to meet this requirement. It is suitable for use as part of a BS 5839-6 Grade F1 interlinked system and meets the 2022 Scotland Technical Handbook standards. Combined with the R200H-N1 heat alarm (for kitchens) and R200C-N1 CO alarm (for rooms with fuel-burning appliances), the R200 series covers the full Scottish requirement in a single compatible product family.
Is the R200S-N1 suitable for landlords and rental properties?
Yes. The tamper-proof sealed battery eliminates the risk of tenants removing batteries, the BSI Kitemark certification satisfies legislative requirements, and the 10-year service life minimises ongoing maintenance visits. The automatic self-testing function ensures the alarm remains operational between tenancy inspections without requiring manual testing by the landlord. The alarm complies with the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 for rental properties in England.
