– Do not use other switches than the PRA-ES8P2S. See section Ethernet switch | PRA-
ES8P2S, page 153 .
– Do not use other fiber transceivers than the PRA-SFPLX and PRA-SFPSX. See section
Fiber transceiver | PRA-SFPLX, PRA-SFPSX, page 161 .
– When a PRA-ES8P2S is used, its fault output contact must be connected to a
PRAESENSA control input, configured as ‘External fault input’. See section
Fault relay
connection, page 157 .
– The PRA-ES8P2S must be powered from a 48 V output of a PRA-MPS3 with battery
backup. See section Power supply connection, page 157 .
Emergency call station Y/N:
The call stations PRA-CSLD or PRA-CSLW must be used in combination with one or more
PRA-CSE call station extensions. Such a composed call station provides visible (LEDs, LCD)
and audible (buzzer) indicators to unambiguously indicate the quiescent condition, the voice
alarm condition and the fault warning condition with indications of the recognized faults. The
system is capable of being simultaneously in the voice alarm condition and in the fault
warning condition. The optional disabled condition is not supported.
–
To indicate the voice alarm condition and the fault warning condition, configure the call
station as an emergency call station.
– Install an emergency call station in accordance with access level 2 and provide
appropriate access restrictions. See section
Location of racks and enclosures, page 18 .
– The emergency call station must be network-connected in a loop with PoE power supply
on both network connections. See section
Power over Ethernet, page 135 .
– Emergency call definitions must have a preconfigured priority in the emergency priority
range 224 - 255. Higher priorities overrule lower priorities in case of resource or
destination conflicts. In case of the same priority the first call gets priority, but for
priority 255 the last call gets priority.
– If the VACIE uses multiple emergency call stations, the priorities between them must be
arranged via the call definitions in the configuration. At any time only one microphone
will be active in any zone.
– To silence an audible warning manually, the emergency call station must be configured
with buttons to acknowledge and reset the fault alarm and voice alarm condition.
Amplifier Y/N:
The PRAESENSA power amplifiers have a built‑in spare amplifier channel that takes over from
a failing channel automatically.
–
Amplifier supervision must be enabled in the configuration.
The amplifier to loudspeaker cabling must be supervised.
–
Use a PRA-EOL end‑of‑line device for each loudspeaker line to detect interrupted or
shorted loudspeaker lines. See section
End-of-line device | PRA-EOL, page 98 .
– In case of A‑group and B‑group wiring for a zone, use an end‑of‑line device for each
group. See sections
Amplifier outputs, page 72 and Amplifier outputs, page 89 .
Multifunction power supply Y/N:
PRAESENSA uses multifunctional power supplies to provide power to the system devices.
–
Only use the PRA-MPS3 power supply with battery backup. See section Multifunction
power supply, large | PRA-MPS3, page 104 .
