The Battery Room
The main battery room adjoins the power house.
This contains a lead storage-battery of some 2,000 ampere-hours, one object of which is to provide a supply of current for a short time during an emergency.
It also serves to light the building, and to provide a small amount of power when neither of the main transmitters is in use.
Still proceeding towards the front of the building, next to the battery room there is a closed-in space where lorries can unload, and beyond this there is a repair workshop and a store for spare parts.
Along one side of the battery room, packing space, and a workshop, there is a passage-way, to the roof of which are fixed the bare copper feeders running to the motor generator room.
