output to other host;
The host line audio can controlled by EVAC - 500 SFT or EVAC - RM/RME and EVAC-500FM/EVAC-500TP.
Note
：
The choice of the current user can see through the EVAC - 500 SFT interface
，
To change the different audio
output
，
Only through use to choose from the panel.
12-All Zones
To select all six zone outputs open or close at the same time.
13-Zone Fault Indicator.
Yellow-The current partition A and B or A or B speaker impedance change, may be open or short circuit. Extinguish-The
current speaker zone loop impedance changes within the impedance of the speaker when it was pre-set.
Note
：
When the host or extension host access system according to the project wiring work needs a resistance to
proofread before obtaining the loop impedance value of the current speaker, please follow below steps
：
Unplug the host back row ID switch. 7
，
Until hear buzzer sing alternately or see panel lights flashing after "FAULT"
then, Put the 7th ID switch it on. When the speaker circuit impedance change more than the current host or extend
the host for the impedance value plus or minus 10% ~ 10%Will record the current changes and inform the user in
the form of light. Zone detection sensitivity is more than 20W
14-Paging Indicator.
When paging, can manually close the zones where no need paging or add new zones.
15-EVAC/ALERT Indicator.
When EVAC and alert emergency broadcast is working, the indicator will be light on.
16-BGM Indicator.
When background music broadcast is working, the indicator will be light on
.
Note
：
Manual broadcast voice messages need choose audio first, then, choose output zone, For example, if you
want output line 3 in 3
rd
zone, you can choose line 3 audio then choose 3
rd
zone. You also can choose 3
rd
zone, then,
choose line 3. Two ways are the same, normally, we choose zone firstly, then choose audio. In this way, each zone will
output audio at the same time, We also can control different zones from the EVAC - 500 SFT operation.
17-Zone Selector.
To select individual six zone output open or close.
18-Zone Output Attenuator.
Increase or decrease the individual zone speaker output loudness at 6 levels and max control of -15dB.
19-Emergency Microphone Input.
Input for the emergency microphone or fireman microphone of priority.
20-Monitor Speaker Attenuator.
Increase or decrease the built-in monitor speaker loudness.
21-Emergency Microphone Gain Control.
It is used to adjust the emergency microphone input sensitivity.
22-Treble Control
.
Increase or decrease the overall treble output.
