A specialised telephone system that is built and installed to meet BS5839 Pt9
The CSL fire telephone system has full duplex audio communications to ensure clear conversations in real fire situations regardless of background noise. With emergency battery backup and constant self-monitoring for faults allowing the CSL fire telephone system to meet all project specifications.
The master panel is normally located at the main entrance of a building for use primarily by the fire officer and the outstations strategically placed around the building for use by fire marshals or fire brigade personnel. Using the fire protected communication link, personnel can assess the emergency situation and implement the appropriate action. This is particularly desirable in high-rise buildings where an evacuation needs to be coordinated to prevent stairwells becoming overwhelmed.
