2..B. PUBLIC ADDRESS SYSTEM:
2.1CONTROLLER:
Alarm controller, shall complies with standards for emergency sound systems (IEC 60849), and shall have the capacity of 6 zone
system controller, built in with 240 W booster amplifier, 12 business and emergency control in – and outputs. The controller has
two BGM source inputs and a mic/line input with configurable priority, speech filter, phantom power and selectable VOX
activation. A total of 16 priority levels can be specified for microphone, call stations and trigger inputs for optimum system
flexibility. The powerful 240 W output section has six transformer-isolated 100 V constant voltage outputs for driving 100 V-
loudspeakers in six separate zones. The 100 V-technique reduces line losses on longer distances and allows for easy parallel
connection of multiple loudspeakers. All zones may be individually selected from the front panel and the BGM output level in
each zone can be individually set in 6 steps. The BGM output is connected to the 70V line, thus it is possible to connect a total
load of 480 Watts in a two channel system combined with a 480 Watt booster. Model number is as specified in the BOQ.
2.2CALL STATION:
6-zone call station, intended for LBB 1990/00 Voice Alarm System Controller. Six zone selection keys, all-call key and
momentary PTT-key for calls Selectable gain, speech filter and limiter for improved intelligibility LED indications for zone
selection, fault and emergency state Call station extension provides 7 additional zone and zone group keys. On each call
station it is possible to select 6 zones with the possibility to connect up to 8 call station keypads (LBB 1957/00) to increase the
number of zones or zone groups that can be selected. Each keypad adds 7 zone or zone group keys. This call station features
selectable gain, a selectable speech filter and a limiter for improved intelligibility, even if the speaker moves in front of the
microphone. Because the call station provides a balanced line level output, it can be positioned up to 1000 m away from the
controller, using CAT- 5 extension cables. Using dipswitches on the bottom of the call station different microphone gain levels
can be select as well as the call station ID and the speech filter. Selected zones are indicated with LEDs on the call station,
three additional LEDs give visible feedback on the active state of the microphone and the system. Green indicates microphone
active, amber indicates that the system has detected a fault (IEC 80649) and red indicates that the system is in the emergency
state. Model number is as specified in the BOQ.
