Redetec is a unique fire control solution providing fire protection in operation critical IT server racks and cabinets. Redetec includes all fire detection, control and extinguishing needed within one 19” rack-mounting chassis. For relatively little cost, Redetec provides fire protection against the potentially devastating loss of capital equipment and company essential data.

Redetec is widely used in critical systems where IT server or Data centres require more responsive fire detection and protection than found in traditional room based total flood solutions. By putting fire protection into the equipment rack enclosure, Redetec is able to better protect essential equipment and data from the effects of a fire incident within the rack. If during normal operations smoke is detected, Redetec’s on board control systems are able to shut down rack ventilation fans
before releasing fire extinguishing gas into the enclosed space and eliminating the risk.

Redetec uses point-type or high sensitivity air
sampling detectors to identify smoke particles.Fire extinguishant gases such as FM200 and Pyrogen (other gases are also available) are used; selected to meet the demands of each application.

Redetec Plus is a further option to the standard Redetec.In addition to the fire detection and control described above, Redetec Plus also provides rack condition monitoring and security management.
Monitored inputs include temperature, humidity, vibration, water detection. Each input has user-settable upper/lower threshold levels and user settable alarm levels. Redetec has network access via SNMP,WEB and Telnet using 10BaseT Ethernet.

Benefits

• Complete rack/cabinet fire solution
• Close protection for high value assets & critical operations
• Faster response to in-cabinet fire incidents
• 24/7 running, no daytime lock-off
  Requires little to no fire engineering design, installation cost or
  floor space
• Reduced extinguishing gas requirement/maintenance costs
• Contributes to responsible environmental emissions policy
• And by distributing protection within cabinets, improves cost
  effectiveness of fire safety policy
• Redetec is transportable, it moves with the cabinet
• Redetec can be extended and networked
• Communication links to IT networks/BMS
  SNMP/Web enabled for greater integration/management control
• Improved control & security integration with main building systems

Advantages

• Puts fire control where the risk is; inside the cabinet
• In the event of a fire incident, Redetec releases only into the cabinet in alarm, minimising gas required, concentrates response
  and cuts downtime
• Cost effective close risk fire protection which is easy to install, simple to control
• Facilitates capital assets & data protection and business continuity
  
• Essential coverage for mission-critical equipment and operations
  with total reliability and cabinet protection
  
• Designed to comply with recognised international fire control
  design standards for fire protection in computer control rooms
  
• Can avoid cost of engineered room fire protection systems
  
• Only small amounts of fire extinguishant gas used in directed local application
  
• Transportable. Redetec protected racks & cabinets can be moved
  to different locations without loss of cover
  
• Ideal solution for manned control rooms and unmanned site
  applications
  
• Totally automatic operation,with remote/manual control options
  
• Worldwide delivery and support structure
