Cabinet Protection - complete and compact

Switch and control cabinets, along with vending machines, contain electronic and electric components in very confined spaces. CPS 1230 extinguishing systems protect this type of cabinet in case a fire occurs inside them as a result of a short circuit, overload, overheating or a component error.

Advantages at a glance

The CPS 1230 cabinet protection system (CPS) is a standardized comprehensive set with all necessary components in one package. The system is specially designed for fire protection of the sensitive and high-quality electronics in control cabinets and offers reliable and residue-free extinguishing through the use of the non-conductive Novec™ 1230 extinguishant by 3M™. The comprehensive set can be easily installed on site, both in the case of new installations and retrofits.

  • CPS 1230 extinguishing systems protect cabinets with electronic and electric components
  • The system prevents the fire from spreading to other facilities in the vicinity of the protected cabinets
  • No extended downtimes in energy supply and production facilities
  • One system can protect up to two cabinets
  • The Novec 1230 extinguishing agent is neither corrosive nor electrically conductive and does not leave any residues
  • New systems can be easily and quickly installed or retrofitted

Design

The CPS 1230 extinguishing system consists of the extinguishing nozzles with the associated supply lines, the extinguishing tank as well as the fire detection and extinguishing control system. One system protects up to two cabinets with electronic and electric components.

How does a switch cabinet extinguishing system work?

CPS 1230 extinguishing systems fight fires in the cabinets that are to be protected, using the NovecTM 1230 extinguishing agent by 3MTM. The extinguishing agent extracts heat from the fire and thus stops the combustion reaction. The Novec 1230 extinguishing agent is stored in a liquid state in an extinguishing agent tank. The extinguishing agent is transformed into a gaseous state only when it is released from the extinguishing nozzles into the cabinets that are to be protected. Novec 1230 is neither corrosive nor electrically conductive, leaves no residues and is highly environmentally friendly.

A CPS 1230 extinguishing system can protect up to two cabinets with electronic and electric compo- nents. Thanks to prefabricated component sets, it is easy and quick to install new systems or to retrofit existing ones. CPS 1230 extinguishing sys- tems protect in the case of fire not only the actual cabinets, but also prevent the fire spreading to other devices in their vicinity.

Fire detection and control technology

Fire alarm and extinguishing control technology

Tried and tested Minimax fire detection and extinguishing control technology ensures reliable fire detection as well as control and function monitoring of the system. Each protected cabinet is monitored by smoke detectors. Unlike heat detectors, these already transmit a signal to the fire detection and extinguishing control panel in the initial stages of a fire. The control panel then initiates the shut-down of the energy supply of the cabinet and controls the electric triggering device of the extinguishing agent tank to ensure that the extinguishing agent can flow into the cabinet. At the same time, it triggers an alarm and optionally transmits a signal to a permanently manned post.

Extinguishing agent tank

Two differently sized CPS 1230 extinguishing agent tanks provide protection for all common cabinet sizes. The extinguishing agent container is placed either directly in the protected cabinet or on the outside, on or next to the cabinet. Inside the extinguishing agent tank, a cushion of nitrogen covers the extinguishing agent and thus generates an operational pressure of 42 bar. The extinguishing agent tank is fitted with a valve with an integrated electrical triggering device.

Extinguishing nozzles with supply lines

A CPS 1230 extinguishing nozzle is installed in the upper section of each protected cabinet. The special geometry of the CPS 1230 nozzles with a spraying angle of 210° ensures that the extinguishing agent is homogeneously distributed throughout the entire cabinet in the event of fire. The appropriate supply lines connect the extinguishing nozzles with the extinguishing agent tank.

Applications

CPS 1230 Cabinet protection systems are an ideal fire protection solution in many cases, e.g. for Switch cabinets in low-voltage switch systems, Control cabinets for production systems or Vending machines for goods and services in connection with commuter transportation systems. CPS 1230 extinguishing systems for cabinet protec- tion not only protect property, but also prevent energy supply and production facilities from longer downtimes.
