Leak-sensing cable helps protect Cabinet War Rooms

Over 2.3 km of TT1000 water sensing cable provides vital protection for irreplaceable artefacts and exhibits for the Cabinet War Rooms Museum in London. The Tyco Thermal Controls’ TraceTek leak-detection system was installed as part of a major refurbishment project at the Treasury building in Parliament Square, which is above the basement-level Cabinet War Rooms.

TraceTek’s TTDM-PLUS panel and TTSIM slave units have been installed at various locations around the building to monitor the sensing cable. The TTDM-PLUS contains the most up-to-date circuit technology and can provide the precise distance and location of any leak. The TTDM-PLUS and TTSIM units are also linked into the building management system by individual volt-free contacts provided by the latest TT-NRM unit.

The TraceTek TT-NRM Network Relay Module provides the capability to add up to 320 individual alarm relays to a TraceTek TTDM-PLUS /TTSIM leak detection network. The TT-NRM communicates with the TTDM-PLUS via the same RS-485 network used for TTSIMs. The TT-NRM can be installed in a wide variety of configurations, allowing numerous leak detection system layout possibilities.

The versatility of this design approach will enable the client to add additional areas and SIM’s to the network in the phased expansions planned for the system.
