Create system documentation to the given scenario including clear stepwise information and include the relevant diagrams. The Fire Department in Newtown has been restructured and is shortly opening a new headquarters building. The headquarters will house all the communications and computer systems for the Fire Department. Newtown Fire Department covers an area of 70 square kilometres and has a Chief Fire Officer who is responsible for firefighting, rescue operations and fire prevention in that area. The Chief Fire Officer is assisted by three Watch Officers who also carry out senior duties and take responsibility for the operational duties of the Fire Department when their watch is on duty. The Fire Department has 3 watches and each is on duty for 8 hours per day. Each watch is made up of 20 firefighters and there are 3 fire engines plus one car for the Watch Officer. All vehicles require two-way communications with the control centre. The control centre has three Controllers on duty at any time who receive calls from the public, liaise with other emergency services when required and maintain contact with firefighters when they are at an incident. When fire engines are required for an emergency, the control centre sends details to a printer in the fire engine bay to provide written details of the incident. This print-out is taken by the Watch Officer as the watch leaves the building to attend the incident. The call centre also updates the firefighting staff via two way voice communication.
