- ACTIVE DIRECTOR,- CIDS BUS,- DEU A,- DEU B,- CAM,- PROG AND TEST PNL,- FWD ATTND PNL,- ADD ATTND PNLS,- ATTND IND PNLS,- LOUDSPEAKERS,- SIGN LAMPS,- AREA CALL PANELS,- PAX CALL LAMPS,- READING WORK LIGHTS,- EMER LIGHT BATTERY,- DRAINMASTS.

To prevent unauthorized access it is necessary to entera code for the battery test.The duration of the test will be up to two hours.During the test, it is possible to use the PTP forother functions.When the test is activated the BAT light in the BATkey comes on. An internal time count is started in theCIDS DIRECTOR.If the test is OK, the BAT OK light beside the BAT keycomes on.If there is a failure message on the PTP and ifannunciator light does not come on, you have to testeach EPSU with their individual test button.When the BAT TEST RESET has been selected, the BAT OKlight and the BAT key light go off.In case of a failure, the respective result will bewritten into directors GND SCAN memory.
