A daring daylight robbery on a jewellers on Dublin's Lower Dorset Street has been stopped by a recently installed security smoke system.

Just after 6pm on the 22nd November, a hooded man wielding an iron bar kicked in the front door of the shop. Proprietor Martin Gear immediately set off the panic alarm, activating the Smoke Screen system which burst into action, filling the shop full of dense, non-toxic, no residue fog, forcing the intruder back out the store. 

'The Smoke Screen is the best investment I have made in the shop. It saved my life. The machine has paid for itself ten times over,' commented Martin.
