Use this combination to trigger the silence instruction to the previously selected zones. If no zones are
selected, this silences on all zones accessible from local front panel.
NOTE: If any EVAC input is active during manual zone silence the activation trigger will override SILENCE
mode.
4.2.5.3.
Use this combination to reset the Compact 500 system. In a network system this will reboot the entire
network. If the reset was triggered successfully, all local LED indicators should start a fast-blinking sequence
during reboot.
4.2.5.4.
Use this combination to trigger the backup amplifier test. This test sequence will simulate an amplifier fault
for each local amplifier channel, one by one, forcing the backup amplifier to engage and take over the
channel where the fault is simulated. The sequence will be displayed on the front panel ZONE LEDs.
NOTE: the backup amplifier test can be triggered only if C500 has backup amplifier enabled.

5. Integrated fireman mic

The front panel of the C500 is equipped with a Fireman Microphone. Take out the handheld microphone
and press the PTT button and enable LIVE EVAC signal transmission to all zones available on the local panel.
This signal is a top priority audio stream and will override any other type of audio signal in the system.
If any zone was previously selected, you will start transmitting to selected zones only.

6. KEY switch

The C500 may be optionally equipped with a security key-switch on the front panel.
The key switch disables/enables the FUNCTION button and the PTT button of the fireman mic. Thus the
access level is protected with an additional step.
The key switch is under surveillance, so in case of electrical or mechanical failure, the key switch fault is
reported,
