emergency alarming, fire alarm announcement and background music playing for 2 zones. It is an ideal
application for small shopping malls, office building and sports venues.
1.2 Performance
Digital tube display screen to display time, power amplifier status, and Fireman MIC status;
One-key alarm and two kinds of editable alarm voices; EMC microphone for on-site voice evacuation;
LED light to indicate system connection status and fault status;
Support speaker line detection (light load, over load and short circuit);
LED display to indicate the type of audio source of the current signal;
1 aux input interface, 1 Fireman MIC input, support offline detection; each paging record is automatically
saved to SD card;
Zone switch keys and LED display to indicate zone working status;
Support AC power supply and 24V battery power supply; support automatically and seamlessly identify and
convert. AC power supply is with the priority;
Built-in two 240W digital power amplifier modules, which can have master and standby amplifier switch
automatically;
Equipped with 24V battery charger, which can be charged automatically when the system is powered by AC;
System error information is backed up by logging in SD card;
A/B line speaker output for two zones; independent power switch and volume control for each zone; with
master volume control, treble and bass adjustment; each channel can output 240W, and the total power of 2
zones need to be within 240W;
2 channel link relay output interface (can control the short circuit of two wires to control other equipment); 2
24V output interfaces give peripheral equipment 24V (not greater than 0.5A) input signal;
2 input dry contacts, which can be integrated with the third-party system (such as the fire alarm system)
through the input of dry nodes;
Network cable interface for connecting to PAVA2200 Fireman MIC;

5. Output dry contacts of 2-channel relay
Under normal conditions, the output dry contact 1 is an open circuit. When an EVAC or ALARM plays,
the output dry contact open circuit becomes short-circuited.
Under normal conditions, the output dry contact 2 is a short circuit. When the system fails, the dry
contact will be changed from short circuit to open circuit.
6. 24V output
Under normal conditions, there is no output. When the system is in alarm state, the two 24V output ports
change from no output to 24V output.

4. Methods for examining common system failures
1. When the digital screen displays b1, please:
check if the network cable for connecting PAVA2200 is loose.
2. When the DC POWER indicator is yellow, please:
check if there input AC power
3. For the device and extended device, when the SYS STATE indicator is yellow, it indicates that there is
a fault in the system detection. Please:
check if the digital tube displays error messages
check if the LED light with detection function is abnormal
4. When the EMG MIC indicator is yellow, please:
check if the handheld microphone is normal
5. When the STATE indicator for each zone is yellow, please:
check if the speaker cable of the corresponding zone is broken or damaged.
