Comparing the fire alarm to the manufacturer's website, the fire alarm is a model 7010.
Actually, it's lock, stock and barrel. Per pedia: Lock, stock, and barrel is a merism used predominantely in the United Kingdom and North America meaning 'all', 'total', 'everything'. The term itself derives from the components of a musket; the 'lock' being the firing mechanism, 'stock' being the wooden butt-end of the gun and 'barrel'; being cylindrical component, concurring 'all' the components of the gun. Another interpretation could be business-related. One would own the lock, as in the building; stock, as in the stock exchange, investments, etc.; and barrel, as in all inventory. Merism: figure of speech by which a single thing is referred to by a conventional phrase that enumerates several of its parts or which lists several synonyms for the same thing.
