IMPROVEMENTS IN OR RELATING TO FIRE SUPPRESSION SYSTEMS

摘要

Described herein is a temperature sensing device in the form of a fastener arrangement 10. The arrangement 10 comprises a bolt assembly 12, a nut assembly 14 and a sensor assembly 16 located within the bolt assembly 12. The sensor assembly 16 connects with a processing module 24 mounted in the nut assembly 14 which processes signals received from the sensor assembly 16. The fastener arrangement 10 operates to hold a liner panel 18 against a bracket 20 as well as sensing temperature in its vicinity. A connector 26 is provided on the nut assembly 14 for connecting with a control system. The fastener arrangement 10 may form part of a fire detection or fire detection and suppression system.
