Hi All,
Please does anyone know where the fire-protected area is usually located near a passenger hoist on site.There is an electrical requirement for a new hoist which states that a secondary emergency supply shall be in a fire protected area at least equivalent to the fire protection of the lift well.

New one on me I must admit, does it mean you have to build a cupboard or protected shaft to protect the secondary supply ?????????? Is it so that if a fire takes out the first supply the lift can still be brought down safely as without power the lift would presumably "lock up" or "fail without danger". What make is the lift and whose codes do you think it was written under. ?? USA?? german?? Japanese??
Is it really intended for site use or is the manual written for pernmanently installed lifts??
Sorry to ask questions but it is my way of opening up the problem.

This sounds a bit like a foreign standard for the use of the hoist for evacuation in the event of fire. In the UK we would require a secondary separate and protected power supply for evacuation lifts above two storeys.

Please permit me to rephrase my question:What is the meaning of a fire fighting area and where can the power supply cable be installed for a fire fighting lift?
Many Thanks,
A.U.

In the UK, a fire-fighting lift in a building is primarily for the use of the fire brigade - although it may be used to evacuate disabled persons by management prior to the fire brigade taking control. If this is what you are interested in, you should consult your local fire officer. An evacuation lift (for use by building management to evacuate disabled persons) may be to a lesser standard than a fire-fighting lift and should conform with BS5588-8:1999 - which gives information on the types of power supply that may be used and the need for fire separation.
