Alarm evaluation in "Emergency operation" mode via Emergency operation
–
processor and "Emergency operation" in the detector
With emergency alarm a "Collective alarm" is given at the B3Q700 with the re-
–
sponse indicator in the detector flashing
With line short circuit and malfunction of the line processor no "Emergency
–
alarm" is given
Alarm evaluation with "Emergency operation" via hardware comparators
–
With emergency alarm the "Collective alarm" is given at the B3Q700 without the
–
response indicator at the detector flashing
Selectable Function "Short circuit = Alarm" also fulfilled with emergency alarm
–
At least one control console per system must comply with standard EN54, i.e. must
have Emergency operation capability and Emergency power supply.
Emergency power supply
This consists of a second supply circuit to stations located elsewhere
–
For this purpose the B3Q700 has 2 de-coupled supply inputs

C-Bus
1)
Two requirements must be met for control consoles located elsewhere. At least
one control console must comply with standard EN54 (i.e. have emergency opera-
tion capability and emergency supply).
EN54 requirements:
Communication as loop line
Operation also in emergency mode
Second de-coupled 24V supply
