Local fire codes often require that sprinklers are installed in critical spaces. When water leaks are a concern, pre-action sprinklers offer a great alternative to regular water sprinklers.

Unlike regular sprinklers, pre-action sprinklers use an automatically controlled valve to keep water out of critical spaces. Only supervisory compressed air is inside the sprinkler pipe during normal operation. In the event of a leak in the piping network, compressed air (not water) escapes the pipe. The loss of compressed air will lower the air pressure in the pipe, causing a control panel to alarm the trouble condition.

Advantage of Pre-Action Sprinklers

• Water does not flow if the sprinkler pipe breaks
• Water does not flow if a sprinkler head is damaged
• Water damage to valuable assets is less likely to occur due to accidents or natural disasters

Pre-action sprinklers are often used in conjunction with water mist or clean agent fire suppression systems. These fast-acting systems act as the first line of defense protecting people, assets and business continuity, while pre-action sprinklers meet minimum local fire code requirements and are the second line of defense protecting the building structure.
