| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | CO alarm chirps once a minute, red LED flashing in time | Low batteries | Fit new batteries without delay | DIY Safe |
N/A | CO alarm gives a double-chirp every 30 seconds, red LED double-flashing along with it | The alarm unit has reached the end of its working life | Replace the alarm | DIY Safe |
N/A | CO alarm chirps and its red LED flashes, both on a 30-second cycle | Fault | Replace the alarm | DIY Safe |
N/A | CO alarm's red LED stays lit with a continuous tone sounding | Malfunction | Replace the alarm | DIY Safe |
N/A | CO alarm sounds loudly and continuously in a 4-beep, 5-second-pause pattern, red LED flashing throughout | The unit has picked up a dangerous concentration of carbon monoxide | Stay calm and get every door and window open. Switch off any fuel-burning appliance you safely can. Should the alarm keep sounding, get everybody out, warn them of the danger, and leave the doors and windows open behind you - don't go back inside. Anyone affected by the fumes needs medical help, and tell the responders CO poisoning is suspected.
Whatever caused it must be fixed before it's used again. | Professional Intervention Required |
N/A | Pressing the smoke alarm's test button produces no sound | — | Look the unit over for damage, confirm it's fitted with the right battery type, the battery cover is on, and the battery is connected properly, then give it a light vacuuming with a soft-brush attachment. If none of that fixes it, don't attempt a repair - the alarm itself needs replacing. | DIY Safe |
Frequently Asked Questions
Q: How do I switch on and test the CO alarm in my caravan?
To get the CO alarm running, take the batteries out of their packaging and fit them into the battery compartment, lining them up with the polarity markings - a correctly fitted battery gives a short beep straight away. Press the test button to check it's working: you should hear one beep, then 4 loud pulses, a short pause, another 4 pulses, and a final beep.
You can also check the green LED is flashing roughly every 30 seconds, which shows the unit has power - this is easier to spot with the lights off or somewhere dark.
Q: How do I maintain and test the smoke alarm in my caravan?
The smoke alarm runs off a single 9-volt battery, which under normal use should last around a year. A red light blinking every 40 seconds tells you the unit is powered up, and if you hear a chirp at that same 40-second interval, that's the low-battery warning - you'll get about a week's notice before it needs replacing, and it's worth doing so promptly since a flat battery means no protection if there's ever a real fire.
Pressing the test button checks the sensitivity, wiring, battery, and horn all in one go, and it's worth doing this after the caravan's been in storage, before setting off on a trip, and roughly once a week while you're using it. For general upkeep, give the alarm a gentle vacuum with a soft brush attachment every three months or so to stop dust affecting how well it works.
