When the main processor of the fire control panel fails, the control panel works in
degraded mode operation. Depending on the control panel type, the fire control
panel can continue to perform the most important alarming and signaling functions
in degraded mode operation.
●
There are no restrictions on the function of the detector when it is in degraded
mode operation.
●
Degraded mode operation does not affect radio cell communication.
●
A fault message is transmitted to the fire control panel via the radio gateway.
The fire control panels support degraded mode operation in different ways.
During planning, therefore, you must observe the information in the 'List of
compatibility' document and the fire control panel documentation. See the
chapter 'Applicable documents'.
You will find more detailed information in the fire detection system documentation.
The fire control panel or the FXS2061 SWING Tool software is used to read out the
detector data.
