Control unit FC700A
When planning a system the following condition must be complied with:
At least one operating unit must comply with standard EN54, i.e. it must be equipped with emergency operation and emergency power supply.
EN54 requirements:
Communication as loop line
The number of wires in the connection cable depends on the application and the distances between the stations:

–Emergency operation circuit and emergency supply are not designed as a loop line
–Emergency supply via separate cable or
12.6Power supply (24V)
Operating unit B3Q700 is designed for the voltage range 18...45VDC
The maximum current at 24V is 400mA
Max. Length of line (approximate):
–For cables ø 0.8mm
–For cable
| The current consumption for the options (parallel indicator panel, |
| must be taken into account separately |
