Autodialler and evacuation system combined for the intervention shaft on the Docklands Light Railway
This intervention shaft was necessitated due to the long distance between stations on this extension to the docklands light railway, additionally we were contracted to supply autodiallers and communication systems to all the stations on this project.
A shaft was dug, halfway between stations to facilitate the evacuation of passengers from the tunnels to the surface.
The lift that was installed was subject to rigorous standards which necessitated the need for an autodialler system to comply fully with BS EN81-28 and BS EN81-70 with the added function of speech between the surface to the lift car, the motor room, the tunnel entrance and the refuge areas.
We combined our autodialler system with a 2 wire bus intercom system, with surface mounted speech units manufactured to the clients specifications.
