Posted By Dave Wilson I would suggest you remove unless you can guarantee that no one will enter, as if its left in it would be an attractive item for robbin! In essence if it is destoyed by vandals it would not be much of a problem (he says) as it is going to be demolished anyway! Remember occupiers liability and your 'reasonableness' not to do anything which could affect people who you may reasonably expect to enter your premises including tresspassers, this does not include a means of fighting a fire I would suggest. So remove all combustable materials as best possible and brick / board up.

Posted By Ashley Wood This is a tricky one! There are absolutely dozens of reported cases of arson on derelict or empty buildings. Your problem would be if squatters gained entry and some fool set fire to the building and someone died! The cost to remove the system would out way its value on the market. Yes, the copper (assuming it is MICC) cable has some value, the detectors have zero value, the panel has zero value, sounders and call points zero value. You may be able to use them (assuming they are not too old and are servicable) someware else, but its not worth it. I would say leave them in. Your problem will be leaving power on in the building to run the system! Look at cutting off all non essential supplies.
