Control panels and smoke damper control from Advanced Electronics have been supplied as part of the first phase of the Kings Cross St Pancras London Underground redevelopment.
The fire detection system uses sixteen MX-4400 4-loop analogue addressable fire alarm control panels, interfaced to Hochiki fire sensors and loop devices. Twelve smoke damper control panels, which are variants of the MX-4000 series fire panels, are used to control 140 dampers around the station. This allows all 28 control panels to be networked together, using Advanced’s Ad-NeT network, which operates over 2-core fire resistant cable, to provide an integrated fire safety solution. The system was installed for Metronet Rail Group by Siemens Building Technology and interfaced to the station’s central SCADA system.
Advanced also developed special damper interface units for this project, which are installed on the smoke damper control panel loops. Each unit provides an output to drive the damper open or closed and three monitored inputs, which monitor the open, close and fault conditions of the damper. Once an open or close command is given to a damper, an automatic fault condition is generated if the corresponding status input has not verified the action within a specified time. LEDs on the smoke damper control panel indicate the status of each damper.
The panels are used to provide control for a number of applications, including addressable emergency lighting and escalator monitoring using linear heat detection.
Phase 1 of the project included the construction of a new Western ticket hall in front of St Pancras station, and the expansion of the current Tube ticket hall.
