9.1 Battery
replacement
FDCW221
The battery of the radio gateway must be replaced when a battery fault for the
radio gateway is indicated on the control panel. The detector line must not be
switched off during a battery fault as otherwise the service life of the radio detector
batteries is significantly reduced!
Prerequisites:
z
The FDnet detector line must be switched on.
z
The radio gateway must be in normal operation and must be fed without
interruption by the FDnet detector line.
z
The new battery is ready for insertion.
The battery must only be replaced by qualified personnel.
Procedure:
1.
Unlock the housing cover of the radio gateway on the front side with pin and pull
it off.
2.
Replace the battery.
3.
Let the housing cover of the radio gateway snap in the housing bottom again.
It may take up to 30 minutes until the battery fault message disappears on the control panel, as the
battery is only checked every 30 minutes. The fault message only disappears when the voltage of the
newly inserted battery is sufficient.
