■TECHNICKÝ POPIS■
BOSCH LBB 1992/00 Plena Voice Alarm Router is an expansion unit that can add six zones and 12 input contacts to the Plena Voice Alarm System. It can use the built‑in amplifier on the LBB 1990/00 Plena Voice Alarm System Controller, and provides inputs and outputs for one or two amplifiers in a multi‑amplifier one or two‑channel system. It provides dual channel operation for calls and BGM simultaneously to a maximum of six different zones, using two amplifiers. Additionally, single channel operation is possible with only one amplifier. Multiple routers can also share one amplifier, including the internal amplifier on the controller unit. It is possible to use any number of amplifiers from one up to the number of routers used. The controller supports A/B wiring.
Functions
BOSCH LBB 1992/00 Plena Voice Alarm Router has a set of relays for zone-switching the power amplifier output(s) to different loudspeaker groups. Each zone can be switched between:
The call channel (call-station selection, all-call microphone, or emergency activation)
The BGM channel (front panel selection)
Off
Two DIP switches
Unit ID rotary control
Mains voltage selector
Power switch
Mains socket
Interconnections Back
12 loudspeaker outputs
Two external amp inputs
Call output
Six volume override outputs
12 trigger inputs
RS-232 connector
Two system interlinks
Two external amp outputs (XLR/balanced)
Power amp fault output
24 VDC power output
24 VDC power input
Two extra trigger outputs
Earth connection screw
Volume override relay contacts are provided for each zone separately for overriding local loudspeaker volume controls. This ensures that priority messages go through with a given volume, even though the local volume controls may be set to a low volume level for background music, for example. Both three-wire and four-wire override schemes are supported. A call or a triggered input will activate these contacts for the appropriate zones, together with an additional voltage-free contact (call-active) for control purposes.
An overload protected 24 VDC output provides power for driving external relays, making an external power
supply unnecessary. The master output channel, or one of the input channels, can be selected to be monitored with headphone connector and LED meter.
Controls and indicators Front
Meter (LED’s for -20, -6, 0 dB and Power ON)
Eight system fault LEDs
12 loudspeaker line fault LEDs
Six EMG call-zone selection buttons
12 EMG call-zone status LEDs
Six BMG zone selector buttons
Six BMG zone status LEDs
