When planning a system, the following condition must be observed:
At least one
operating unit must satisfy the EN54 standard, i.e. be equipped with
degraded mode and emergency supply.
EN54 requirements:
 Communication as loop line –> design C bus as loop line
 Operation even during degraded mode –> 3 extra wires for emergency
operation
 Second disconnected 24 V supply –> 3 extra wires or autonomous
supply
The number of wires in the connection cable depends on usage and the distances
between the stations:
 Is the operating unit supplied with 24 V by the control panel or autonomously?
 Is an emergency supply according to EN54 also managed?
 Is the degraded mode path (emergency operation) also managed?

Notes:
– Degraded mode path also needed between CPUs or to a remote gateway
– Degraded mode path and emergency supply are not designed as loop line
– Emergency supply via separate cable or C bus return
17.4 Voltage supply (24 V)
 The AlgoPilot B3Q... operating units are designed for the 20..30 V DC voltage
range
 The maximum current at 24 V is 400 mA
 Max. lengths of line (approximate values):
– With cable of ø 0.8 mm –> 180 m
– With cable cross-section of 1 mm
2
–> 360 m
 The power requirement for the options (fire brigade operating unit, parallel dis-
play, printer, PSA/pager, LON plug-in unit) must also be taken into account
