Mini smoke alarm for caravans
Updated: 20 October 2026
You are fitting a small ceiling in a campervan, and one disc feels as if it should cover smoke, the cooker, and the heater. A mini smoke alarm for caravans is only the smoke half of that job. A touring caravan or motor caravan that is new and NCC-approved still needs a smoke alarm to BS EN 14604:2005 and a separate carbon monoxide alarm to BS EN 50291-2:2019. Nothing in this amazon.co.uk set detects carbon monoxide, and a battery mini is not the mains system a new holiday caravan or park home is built to. House rankings stay on the [Mini smoke alarm](/hub/fire-protection/mini-smoke-alarm) comparison. Products Compared used Kidde UK's holiday note, the NCC scheme summary, FireAngel's leisure-vehicle guidance, and Devon and Somerset Fire and Rescue, on 20 October 2026. There is no van test of these ASINs. A qualifying Amazon purchase can earn a commission at no extra cost to you.

Smoke alarm and carbon monoxide alarm are two devices
Kidde UK's holiday support page states the NCC line for new touring caravans and motor caravans: at least one smoke alarm to BS EN 14604:2005 and one carbon monoxide alarm to BS EN 50291-2:2019, or a single combined unit that meets both standards. Kidde then lists its own NCC-verified parts. None of those models is in this comparison, and none of our listings claims to be that combined unit. A smoke alarm watches for particles from a fire. A CO alarm watches for a gas you cannot see or smell from a heater, a cooker, an engine, a generator, or a barbecue beside the van. One sensor does not do both jobs because the listing is small.
Devon and Somerset Fire and Rescue make the same split in plain language: fit a smoke alarm, test it monthly, do not take the batteries out, fit a CO detector, and keep the vents clear. They also say you should be able to tell the site operator how to find your pitch. FireAngel's guidance, which is their advice rather than a test of Heiman or X-Sense, puts the CO alarm in the same room as the fuel-burning appliance, about 1 to 3 metres away horizontally, and not directly above the heat or the steam. In a van that is one living-and-sleeping space, one CO alarm can cover that room. A separate sleeping cabin needs its own. This page does not name a CO model to buy.
A combined alarm is allowed by Kidde's NCC note only if that one product meets both standards. Nothing loaded here says it does. Budget for a second device. The house checks that sit beside this are on the mini smoke alarm buying guide.
Touring van or holiday caravan
The battery mini belongs, if it belongs at all, in the touring and campervan case: you need a smoke alarm to a stated BS EN 14604 line, you will screw it up, and you will buy the CO alarm separately. That is not the same rule as a new holiday caravan or park home under the NCC manufacturer scheme. NCC guidance note GN17, for products made from 1 September 2022, describes Grade D1, category LD2. In one sentence, that is mains power with a tamper-proof standby supply, interlinked where there is more than one detector, a smoke detector in the hallway, a heat detector in the kitchen, and a smoke detector in the lounge unless the lounge is open to the kitchen. Smoke detectors are to BS EN 14604 and heat detectors to BS 5446-2. A standalone battery mini does not meet that scheme.
GN17 is the manufacturer scheme for those holiday caravans and park homes. It is not a claim that every second-hand van in Britain is illegal without it, and this page does not turn a private sale into an offence. If you own a holiday caravan built to that scheme, keep the mains system and treat a mini only as an extra beside it. If you are in a touring van or a camper you use at weekends, the smoke half can be a sealed battery alarm that states the standard, screwed to the ceiling, with the CO alarm next to it in the shopping list.
A mini can still be an extra beside a mains system. It cannot replace the Grade D1 layout.
Where to fit it in a small space
FireAngel's leisure-vehicle guidance, labelled as theirs, puts an optical smoke alarm on the ceiling, as central as you can manage, at least 300 mm from lights and walls. That is the same idea as the 30 cm clearance in a house, and in a van the lights and the roof vents eat the space quickly. A wall is only acceptable if the leaflet for your alarm allows it. If it does, FireAngel's note puts the detection element about 150 to 300 mm below the ceiling. Follow your leaflet rather than a generic wall height. The house sequence is on how to fit a mini smoke alarm.
Cooking in a van sets smoke alarms off. The answer is not to pull the cell or to bag the alarm in a drawer while the grill is on. A hush button is the practical control, and then the alarm has to go back to watching. If the kitchen is a separate zone, that zone wants a heat alarm, not this mini. Devon and Somerset say that if a solid-fuel burner keeps tripping the smoke alarm, move the smoke alarm, and keep the vents clear.
Cold and damp are the van problems a house fitting page does not solve. The X-Sense magnetic listing wants pad surfaces above 15 °C, so a magnet in an unheated van overnight is a poor bet. Prefer the screws. FireAngel advises taking their own alarm out of a van that sits empty all year, because damp can affect the battery, and refitting it at the start of the season. Read that as a reason to check your leaflet before you leave a sealed unit in a wet van from October to March. It is not a measured failure of any ASIN in this set. If you cannot reach the ceiling, or the van needs mains detectors, use a qualified fitter. This page does not describe 230 V wiring.
Which minis in this set fit that job
If the job is a battery smoke alarm with a stated EN 14604 line, and you will screw it, three listings are the candidates. The Wisualarm S05-A is about £11.99, photoelectric, with EN 14604, UKCA, 85 dB within 3 metres, and screws or a 3M sticker. Use the screws. The Heiman HS1SA one-pack is about £19.99, with EN 14604, UKCA and LPCB named, and a bracket, screws and dowels on the included line. It does not state decibels, and UK reviews report early chirps, so a van that sits unused is a hard place to ignore a chirp you will not hear until spring. The X-Sense XS01 screw listing is about £16.99, with EN 14604 and screws, and no decibel figure on that page. The magnetic XS01 states 85 dB and still includes screws. Use those screws when the roof is cold.
Skip the Yezala KD-133A as the only alarm. It is about £5.99, UK reviews say three AAA cells, and the listing does not name EN 14604. One UK review did fit a Yezala in a camper van, which shows the size works in a vehicle, not that the missing standard line has gone away. Skip the Spreadtron three-pack as the certified pick. EN 14604 is not named, and the lead fixing is 3M tape. Skip the XS01-M unless you already have the SBS50 base. The Secair at about £14.49 is 52 mm and does name EN 14604, and one UK review fitted it in a motorhome, but the file has only two UK reviews and one of those is a low-battery bleep at about five months. That is too thin to be the van pick.
Common questions
Can you use a mini smoke alarm in a caravan or campervan?
Yes, as the smoke alarm, if it states BS EN 14604, you screw it to the ceiling, and you fit a separate carbon monoxide alarm to BS EN 50291-2. That is the NCC line Kidde UK quotes for new touring caravans and motor caravans. It is not a substitute for the CO alarm, and it is not the mains Grade D1 system for a new holiday caravan or park home.
Does a new NCC touring caravan need a smoke alarm to a named standard?
Kidde UK says a new NCC-approved touring caravan or motor caravan needs at least one smoke alarm to BS EN 14604:2005 and one CO alarm to BS EN 50291-2:2019, or one combined product that meets both. None of the listings in this comparison is a CO alarm or a combined unit. Check the standard line on the smoke alarm you buy, not only the diameter.
Why do you still need a carbon monoxide alarm?
Because these smoke alarms do not detect carbon monoxide. Heaters, cookers, engines, generators, and barbecues beside the awning are CO risks Devon and Somerset and FireAngel both flag. Put the CO alarm in the same room as the fuel-burning appliance, about 1 to 3 metres away horizontally, not directly above the heat. A separate sleeping space needs its own CO alarm.
Is a battery mini enough for a new holiday caravan or park home?
Not as the scheme system. NCC GN17, for holiday caravans and park homes made from 1 September 2022, describes Grade D1 category LD2: mains with a tamper-proof standby, interlink where there is more than one detector, hallway smoke, kitchen heat, and lounge smoke unless the lounge opens onto the kitchen. A battery mini can sit beside that system as an extra. It does not replace it.
Where should the smoke alarm sit in a small van?
On the ceiling, as central as the roof lights allow, at least 300 mm from walls and lights, following FireAngel's leisure-vehicle guidance and your own leaflet. Do not put it in the cooking plume and then remove the cell when dinner sets it off. Use the hush button, then let it watch again. A separate kitchen zone needs a heat alarm, not this smoke alarm.
Will a magnetic pad hold on a cold ceiling?
Do not count on it. The X-Sense magnetic listing wants the surface above 15 °C. An unheated van misses that. Screw the alarm up. Listings in this set that include screws are the ones to take on the road, even when a pad is also in the box.
Should you leave a sealed alarm in a damp van all winter?
Read the leaflet. FireAngel tells owners to remove their alarm from a van that sits empty all year because damp can affect the battery, and to refit it at the start of the season. That is their advice, not a test of the alarms in this comparison. A chirp you only discover in April is a unit that was not watching. If the van needs mains detectors, use a qualified fitter.
