Switched off LEDs are never activated, i.e. the DBS728 behaves like a DBS721. The degraded fire alarm is a fire alarm which occurs during degraded mode operation of the fire control panel. Degraded mode operation is a defined reduced operating mode which occurs when part of the fire detection installation fails.
The information in the 'List of compatibility' and in the corresponding control panel documentation must be taken into account during project planning. 3.6.4 Service indicator The interbases DBS721, DBS728, and DBS729 have a yellow LED to indicate when servicing is required.
