In common with other AA sites Quarantine (command post) had a lookout tower standing about six metres tall. It was built of timber and was complete with a built-in ladder, trapdoor and spotters’ chair. (Des Lambert, former gunner at the ‘Quarantine’)
This command post was the nerve centre of the Quarantine Battery. A Vickers Predictor MkIII and Mk IV Height and Range Finder were mounted above the underground room and its plotting table. Communications was maintained by telephone. During enemy raids the post, or CP, was a hive of activity and a jumble of voices as each member performed his own specialised duties.
Action began with the enemy raiders picked up by radar and the plots passed to Fighter Sector at Berrimah. The information was then relayed to the fighter squadrons, the anti aircraft operations room, and on to the gun and searchlight batteries around Darwin.
The crews were then brought to action stations. Personnel raced to their guns while those in the CP operated the Gun Laying set and plotted the enemy range and height. The Preditor laid the projected path of the enemy, direction of the guns and fuzing of the projectiles. Once the guns had all this information they were fired. The sequence was repeated while enemy aircraft were in range. The spotter in his seat on the lookout tower provided a running commentary on the action.

Above text is taken from the sign on the site. Needless to say, the 'enemy' as so often referred to was the Imperial Japanese Navy Air Service (Japanese: 大日本帝國海軍航空隊, Dai-Nippon Teikoku Kaigun Koukuu-tai). Many of the sites around Darwin only refer to 'the enemy' and not to specifically who the enemy was.
