Dry Pipe Sprinkler System

Dry pipe system is a sprinkler system employing automatic sprinklers installed on a piping system containing air. systems provide automatic protection in spaces where freezing is possible. dry pipe systems are the second most common sprinkler system type. In regions using NFPA regulations, dry pipe systems cannot be installed unless the range of ambient temperatures reaches above 40F.The dry pipe valve and related equipment must be in a heated location.sprinkler system.The sprinkler heads in a deluge system are open, meaning they don't have a trigger function and are activated simultaneously.They are most often used in unheated buildings, in parking garages, in outside canopies attached to heated buildings, or in refrigerated coolers.dry systems have a slower response time, they should be converted to wet-pipe systems as soon as sufficient heat becomes available. 

      

Dry Pipe Fire Sprinkler Systems Include

Loading docks

Commercial freezers

Residential attics

                                               

Advantageous for protection of collections and other water sensitive areas. This perceived benefit is due to a fear that wet system piping may leak, while dry pipe systems will not. However, the same potential for accidental water damage exists, as dry pipe systems will only provide a slight delay prior to water discharge while the air in the piping is released from the pipe.                      

Safety Fire Alarm System in india

The Alarm System has varied applications and is used across many industries for security purpose.The Fire Alarm panel is the component, the hub of the system monitoring inputs and system integrity, control outputs and relays information.Primary Power supply Commonly the non-switched 120 Volt Alternating Current source supplied from a commercial power utility. In non-residential applications, a branch circuit is dedicated to the fire alarm system and its constituents. "Dedicated branch circuits" should not be confused with"Individual branch circuits" which supply energy to a single appliance.Secondary (backup) Power supplies component commonly sealed, lead-acid storage batteries or other emergency sources including generators, is used to supply energy in the event of a primary power failure.Initiating Devices component acts as input to the fire alarm control unit and are either manually or automatically activated.

Fire detectors must be coupled with alarms. Alarm systems provide notice to at least the building occupants and usually transmit a signal to a staffed monitoring station either on or off site. In some cases, alarms may go directly to the fire department, although in most locations this is no longer the typical approach.
