Praesideo 3.5 Installation and User Instructions 9 System Configuration

alarm buzzer is reactivated when the faults have been acknowledged but not yet resolved and reset.

•Report loudspeaker line fault (PRS-SVCO) - Specifies whether LBB4440 Supervision Control Boards that are used for line supervision (see also section 43.3.5) must report faults immediately (Immediate report) or must check again before reporting faults (Recheck before fault reporting). When the system must comply to evacuation standards, select Immediate report to make sure that faults are reported within 100 s. In systems with long loudspeaker lines and many supervision boards, the chance of getting a false (not valid) supervision fault event can be reduced by rechecking before the fault will be reported. Then the system is less sensitive to disturbances in the communication caused by external noise sources or crosstalk between wires.

•Disable network controller on internal fault - This function is intended for systems that contain a redundant network controller. If an internal fault in the master network controller occurs (e.g., a flash card error), the master network controller is disabled and the spare network controller takes over the tasks of the disabled network controller. If the system contains only one network controller, select No.
