Supervision

18. 1

Introduction

If the Supervision switch (see figure 17.1) is in the ON
position, supervision is enabled. If it is in the OFF
position, supervision is disabled.
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.
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 18.1) to indicate that
supervision is switched off.

18.2 Processor reset
18.2.1 Watchdog
If supervision is enabled (see section 18.1), 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.
18.2.2 New firmware
A processor reset sometimes happens after new
firmware is installed. make sure the Service PID
switches are put back to the correct position. The
correct positions are:
• SEL0 and SEL1 to ON
• Enable Firmware Download to OFF.
18.3 Network
If supervision is enabled and network supervision is
switched on (see section 18.1), the connections from the
voice alarm controller to the voice alarm routers and
remote controls are supervised. When any voice alarm
router or remote control is missing during a network
check, a network error is reported.
18.4

Power amplifiers

If supervision is enabled and call power amplifier
supervision is switched on (see section 18.1), the call
power amplifiers in the system are supervised. If
supervision is enabled and BGM/Spare power amplifier
supervision is switched on (see section 18.1), the BGM
and spare power amplifiers in the system are supervised.
