①Connect the electricity AC 110V power supply.
②Turn the power switch to the ON position.
③Can hear the relay beat sound when connect the electricity.
④Panel indicator will show the current system status.
2. Manual self-test:
①Press INDICATION TEST on the front panel.
②There are three colors on the panel----- green, red and yellow light in turn, other lights are turn
on, monitor is turn on, the relay beats in turn to finish the system self-test.
5.2 Emergency function
1. Emergency voice function
1) Manually press the EMERGENCY button, red light flashes;
2) Press alert msg button on host panel to play alert voice language information, the response is
decided by the PC configuration. Turn on the zone need alert message and turn off the zone
do not need alert message.It will remember the previous setting for next trigger.
3) Press the EVAC msg button on host panel to play EVAC Msg voice language information,
the response is decided by the PC configuration. Turn on the zone need alert message and
turn off the zone do not need alert message.It will remember the previous setting for next
trigger.
2. Trigger emergency function
1) Wiring diagram of short circuit mode:

15
2) Wiring diagram of level trigger mode
(Note: Dry contact trigger mode can be configured on the PC, can configure level trigger or
LINE 3 as a sound source, after the emergency trigger can not restore the original play state.)
5.3 Local sound source play
Sound source selection
Press the key selection button to select the source channel. The corresponding indicator indicates
the currently selected source. When LINE7 indicator turn on means select MP3.
1. Sound source play of each zone
a. The current selected audio source for MP3, turn on according zone can play MP3 sound source,
press all zone button, all zones will play MP3. When you turn on the different zone, the zone
status light is normally displayed in green.
b. When the current source is selected as background music, press zone 1 ~ 8 button to turn on or
turn off current zone.
Through the MONITOR button to turn on or off the monitoring function, ensure monitor volume,
main volume must be moderate, to ensure that at least one zone is turn.

5.4 PTT paging
Press the EMERGENCY button, then press the button on the PTT microphone to turn on the
corresponding zone paging (need configure on PC). You can speak after the reminder tone.
Please do not release the button during the speaking or it will automatically turn off paging
and make a tone. In emergency mode PTT paging will automatically record and save the audio
in the TF card.
(Note: PTT has the highest priority in the system, but the host MP3 shared source is a separate
module, not subject to its intervention.)
5.5 Line detection
Detection accuracy: <25%
Minimum detection power: 10W
Maximum detection power: 500W
Installation of the new device requires sampling the speaker impedance, the specific operation
is as follows:
1. Install new equipment , connect speakers for each zone.
2. Press impedance detection button on the rear panel, the system will be connected to each
zone to sample the load, during sample period can hear during the relay inhalation of the
sound, when the lights all off, indicating that the load sampling success.
3. Verify the impedance detection is valid or not:
1) Open circuit detection ----- disconnect any zone output, press system fault self-test
button in the front panel until the sound and light self-test is completed, the indicates
is orange and computer state is open (open) then connected to the speaker, press the
self-test switch, and returned to normal state.
PTT button

17
2) Short circuit test ------ Short circuit any zone output, do not need to press system fault
self-test button on the front panel, Indicates light is orange and computer status short
(short circuit). then connected to the speaker, press the self-test switch, and returned to
normal state.
3) Impedance 25% change detection ------ sampling 30W speaker impedance, plus or
minus 7W, press system fault self-test button on the front panel, the indicate light is
orange and computer status is fault. Then connected to the 30W speaker, press the
self-test switch, and returned to normal state.
5.6 Volume control
Monitor volume adjustment
Zone 1 ~ 8 volume adjustment
Host volume

1. Host volume control is control the volume of the entire machine, the adjustment will affect
the 1 ~ 8 zone volume. Zone volume adjustment only adjusts the corresponding zone volume,
does not affect other zones.
2. Amplifier output monitor
Press the MONITOR button to turn on or off the monitor, Light on means amplifier monitor is
turn on, light off means amplifier monitor is turn off.
5.7 IP address Reset
Press the IP reset button to reset the host IP address: 192.168.1.253.
5.8 Power-down switching function
Connect battery of 24V 20A / H or above, 24V DC indicator light is green, when unplug ~ 110V
electricity plug, automatically switch to 24V power supply mode.
