If you run a hotel, dealings with the local fire brigade are part of the little inconveniences that keep you up to the mark. To run a hotel in this country, I legally have to have a Fire Certificate, this has a plan of the hotel and marks on the plan the site of all bits that I have to have to comply with regulations - smoke alarms, heat alarms, call points, emergency lights, fire notices, water based fire extinguishers, powder based fire extinguishers, a log book, etc. Every year they come to check that all is in order and that I have not ripped them all out in a fit of anti-establishment pique.
False alarms are a common bugbear of any alarm system.
Think about how many times you have heard fire alarms, burglar alarms, car alarms. The ubiquitous alarm bells ringing in high streets across Britain have become so part of every day life, that I am sure not one person in a hundred takes them seriously. However in a hotel, we must take every time the alarms go off seriously. The system must be checked for the cause. In our last hotel we burnt logs, and one Christmas day the chimney went up in flames.
