MSG/ALERT MSG” Lose voice information or loss SD card
；
Extinguish—— “DVA8 MSG/ALERT
MSG” Normal.
Note: 1."DVA8 voice information" refers to the DVA8 voice ALERT and voice
；
2. If you need to
manually play DVA8 voice messages
，
Need to enter the emergency mode, Then press the
voice messages button; 3. System default “DVA8” Voice priority is higher than "ALERT". Can

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:- Zone Emergency Microphone or Remote Microphone Indicator.
When paging, can manually close the zones where no need paging or add new zones.
15:- Zone Emergency Broadcast Indicator.

zone, For example, if you want output line 3 in 3rd zone, you can choose line 3 audio then
choose 3rd zone. You also can choose 3rd 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 DVA8- 500 SFT operation.
17:- Zone Selector.
