R200C-1 vs COA10 carbon monoxide alarm is a useful model-level comparison when the job calls for a stand-alone, sealed-life CO alarm and the handover details matter. Both units give the installer a straightforward, self-contained option, but their published feature sets are not identical. The practical choice comes down to which controls, indicators and record-keeping features suit the job—not a vague “all alarms are the same” assumption.
This guide compares the exact Honeywell Home R200C-1 and Arctic Hayes SleepSafe COA10 stocked by APM. It does not replace the current manufacturer instructions, a site assessment or applicable installation requirements.

Those points are a buying comparison, not a claim that one model is automatically right for every property. Confirm the exact model reference on the order, check the current instructions and make the installation decision from the actual site conditions.
Choose by controls and handover, not the front-cover promise
“Ten year” is the obvious headline on both products, but it does not finish the specification. The day-to-day controls and the information available at handover are what distinguish the models.
The Honeywell Home R200C-1 carbon monoxide alarm uses the device surface as its TEST/SILENCE button. Resideo also publishes a 48-hour alarm-memory function, an end-of-life signal and an auto-dimming green power light. For a contractor, that makes the R200C-1 worth considering where the customer needs a simple explanation of the front control and visible status information.
The exact model suffix matters. Resideo states that the “one-go-all-go” feature belongs to the R200C-N interconnected series; it also lists wireless connectivity as “No” for the R200C-1. Do not sell or hand over the stand-alone R200C-1 as an interlinked model. That one suffix check prevents a specification error that a broad family name can hide.
The Arctic Hayes SleepSafe COA10 carbon monoxide alarm puts a different emphasis on status indication. Arctic Hayes publishes normal, alarm and fault LED modes, along with low-battery and end-of-detector-life warnings. It also lists a test/silence function and alarm memory. That gives the installer a clear set of points to demonstrate and record at handover.
Build a clean carbon monoxide alarm handover record
A sealed-life alarm removes routine battery replacement from the normal customer conversation, but it does not remove the need for a proper handover. Record the make, full model, installation date and the alarm’s stated end-of-life basis. Keep the manufacturer instructions with the property records and show the responsible person how the test/silence control and status indicators work.
On managed properties, model-level records make future maintenance more reliable. “CO alarm fitted” is too loose when the next visit needs the correct instructions, indicator meanings or replacement reference. “Honeywell Home R200C-1, EAN 3603940006476” or “Arctic Hayes COA10, EAN 5012804501763” is precise and searchable.
Before leaving site, verify that the supplied product and packaging match the order, complete the checks required by the current instructions, and document the result. If the job specification calls for interconnection, remote signalling or another system function, neither product name alone proves suitability. Check that requirement before purchase rather than trying to bridge a specification gap at the end of the job.
Important safety boundary
A carbon monoxide alarm is a warning device. It is not a substitute for correct appliance installation, ventilation, servicing or investigation of a suspected source. Do not improvise alarm placement from a general web article: use the current instructions for the exact unit and follow the requirements that apply to the property and work scope.
If an alarm activates, treat it as a safety event and follow the unit instructions and current emergency guidance. Do not silence the unit and continue normal occupation while assuming the cause has cleared. Customers with specific medical concerns should seek appropriate medical advice.
Which stand-alone CO alarm should you order?
Choose the R200C-1 when its exact published controls and indicators—particularly the large TEST/SILENCE surface, 48-hour alarm memory, IP44 rating and auto-dimming power light—fit the specification. Choose the COA10 when its three-mode LED indication, low-battery warning, end-of-detector-life warning and Arctic Hayes handover format fit the job.
Either way, order by full model and barcode, not by a generic “10-year CO alarm” description. That keeps the product, instructions and maintenance record aligned.
