Has any one come across this situation Carbon Monoxide detector fitted in property with solid fuel heating (no gas in property) Alarm goes off - out of hours maintenance contractor called - not a gas engineer Engineer puts fire out and vents building, resets alarm. incident past on to day crew for further investigation and any repairs or replacement to solid fuel boiler and chimney. Does anyone have a procedure for dealing with situation?

MB1 the question was not about detectors. The question was does anyone have a procedure for dealing with the incident described. MEden I suggest your engineer acted quite correctly. He ensured the fire was extinguished and vented the premises. He then reset the alarm in case the problem arose again before the day team carried out a fuller investigation and put repairs in hand. What else do you expect to be done? The fault was managed and passed on to those who could deal with it. The situation was controlled and the risk averted, what more do you think is necessary?
