4.5 Supervision
4.5.1 Introduction
If the Supervision switch (see figure 4.1) is in the ON
position, supervision is enabled. If it is in the OFF
position, supervision is disabled.
If the Supervision switch is in the OFF position, the
Disabled indicator on the front panel of the voice alarm
controller is lit (see figure 4.2) to indicate that
supervision is switched off.
4.5.2 Overview
The supervised functions can be configured with a PC
and the configuration software. To basic systems, the
default settings apply (see table 4.2).
4.5.3 Processor supervision
If supervision is enabled (see section 4.5.1), the
processor of the voice alarm controller is supervised by
a watchdog. If the watchdog triggers, the Processor
reset indicator on the front panel of the voice alarm
controller is lit. Then, the program memory is checked
and the processor resumes operation within 10 seconds.
The indicator remains on until the fault is acknowledged
and reset.
Note
Supervision is only necessary for systems that
have to comply to the IEC60849 evacuation
standard. If the system does not have to comply
to this standard, leave the switch in the OFF
position.
