Not the usual about gassing but our Laika is fitted with this alarm with a separate sensor near the floor. I have been on the website of the company who made it, Nereus Alarms, and tried phoning them but it only rings once and then goes unobtainable. It is not listed on their website and I just wondered if anyone has one of these and does it also detect smoke and carbon monoxide. I would suspect not but any help from anyone would be appreciated.
