- Public Address Function
- Paging Function
- Software Configuration Function
MAIN AND BACKUP POWER SUPPLY
The main and standby power supplies are provided with the ZS-2000M. The methods by which the power
supply detects faults can be configured through the software. In case of a main power supply fault, the main
power supply indicator light on the front panel of the ZS-2000M turns yellow, and the output fault
automatically causes the backup power supply to provide power instead. After the main power supply is
returned to normal, it automatically again supplies power and the backup power supplies resume their
standby presence.
POWER SUPPLY PROTECTION
The ZS-2000M power supply is protected. In case of a short circuit or other fault within the ZS- 2000M, the
main power supply is disconnected automatically.
FAULT DIAGNOSIS
The ZS-2000M automatically detects equipment states, records fault logs, and prompts operation managers
through the fault detection function.
In case of a system fault, the ZS-2000M can immediately detect corresponding faults. The ZS- 2000M fault
indicator light turns yellow, the fault buzzer emits a prompt tone, and the fault information are recorded in the
operation log.
The ZS-2000M can detect faults including main and backup power supply faults, emergency microphone
faults, communication faults, loudspeaker circuit faults, earth fault and power amplifier faults (such as power
faults, protection faults, and single output circuit faults).
LINE FAULT DETECTION
The ZS-2000M can detect loudspeaker circuit faults. When the ZS-2000M detects a short circuit, the
ZS-2000M can automatically disable the output channel and stop broadcasting so as to prevent the power
amplifier from being protected.
During installation and commissioning, users can set upper and lower redundancy range circuit impedance
limits through the software. If the circuit impedance is higher than the upper limit, the ZS-2000M reports an
open circuit. If the circuit impedance is lower than the lower limit, the ZS- 2000M reports a short-circuit fault.
MONITORING FUNCTION
ZS-2000M is able to monitor the audio of the loudspeakers, zones, and sound sources from 4 output
channels of the power amplifier.
SELF-TEST FUNCTION
The ZS-2000M initiates the self-test function by manually pressing the “Self-test” button. In addition, when
the test is being performed, all indicator lights on the front panel of the ZS-2000M turn on, the fault indication
buzzer continuously buzzes.
The ZS-2000M performs uniform management of equipment such as the ZS-1500/ ZS-2250/ ZS-4125. During
the self-test, all equipments directly connected to the ZS-2000M perform the self-test function.
AVC FUNCTION
Each ZS-2000M provide 4 AVC interfaces, which use for connecting the noise detectors. So as the system
can adjust the broadcast sound pressure level automatically for better definition of audio.
ZS-2000M can simultaneously support 2~4 AVC functions. Because AVC, PTT recording and Network
monitoring share the 4 audio channels, if need to enable the PTT recording and monitoring functions, they
will respectively occupy 1 audio channel, the number of available channels for AVC will reduce. When
configure the project, please note this requirement.
Beside, only ZS-2000M work in B mode, the AVC function is enabled.

VOLUME CONTROL
The user can directly adjust and control the broadcasting power amplifier volume by pressing the buttons on
the front panel of the ZS-2000M.
The volume can only be set by using the Automatic Volume Control (AVC) function. The ZS-2000M can
automatically detect and adjust the zone broadcasting volume according to the configuration parameters.
When the system is working in voice alarm mode, the volume is fixed to maximum level, and manual setting
is unavailable until the system recovers public address mode.
POWER AMPLIFIER MANAGEMENT
The ZS-2000M can automatically detect the operating states of the power amplifier. Switching between the
main and backup power amplifiers is achieved based on the number of power amplifiers connected to the
system and recognized by the system software, described below in detail by the following:
- Configuring the number of power amplifiers
The software can be used specify the number of connected power amplifiers according to their type.
The default number of connected power amplifiers is two.
- Switching between the main and standby power amplifiers
-An audio matrix is used for ZS-2000M zone control so that any power amplifier can be defined
as a standby power amplifier for another power amplifier through the software. When the ZS-
2000M detects a main power amplifier signal fault, the ZS-2000M automatically switches to the
standby power amplifier.
-The switching sequence is controlled according to the power amplifier priority level. If two or
more power amplifiers share the same priority level, the ZS-2000M switches to a random power
amplifier of that priority level.
-A maximum of three main power amplifiers and one standby power amplifier can be configured.
ZONE CONTROL
The power amplifier zone control mode is configured through the software to be either the power matrix
mode or direct drive mode.
For the power matrix mode, the power amplifier and loudspeaker zones constitute the power switch matrix,
as well as determines the matrix size according to the actual number of power amplifiers and zones. Any
sound source can be selected for any zone using the matrix.
For the direct drive mode, one fixed channel power amplifier drives one or several zones, in this way
improving the output power of the zones being driven. Zones of the same power amplifier broadcast the
same sound.
VOICE INFORMATION MANAGEMENT
Build-in 1GB nonvolatile memory: 500MB (The maximum storage time is 96 minutes.)can store audio files and
350MB (The maximum storage time is 67 minutes.)used for recording
Sound files can be broadcasted separately, and can be prioritized in a file playlist.
One of the audio files can be configured as a pre-signal and be played before any regular broadcasting
operations.
Voice information broadcasting modes include the broadcast times priority levels and time delay can be set
in the definition of broadcast operations tasks
EMERGENCY VOICE ALARM FUNCTION
The ZS-2000M can be linked with the fire alarm system through dry contacts, RS-485 cables, or through the
Ethernet network. When the system is configured to be linked with a fire alarm through the configuration
software, the fire alarm controller can send fire control signals to ZS-2000M through the Ethernet network.
When the ZS-2000M receives fire broadcasting initiation signals, the ZS-2000M immediately interrupts all
non-emergency broadcasting functions and enters the emergency voice alarm state. The ZS-2000M can
automatically trigger alarms for areas with emergencies according to the initial fire alarm controller signals.
The system can also configure emergency broadcasting evacuation schemes through the software and
facilitate personnel evacuation through voice prompts.

Class-D Amplifier (ZS-1500/ ZS-2250/ ZS-4125)
This chapter describes the ZS-1500/ZS-2250/ZS-4125 characteristics, functions, appearance and
specifications.
In the system, the ZS-1500/ZS-2250/ZS-4125 are used to amplify audio signal power and drive many
broadcasting loudspeakers.
PRODUCT CHARACTERISTICS
The ZS-1500/ ZS-2250/ ZS-4125 have the following main characteristics:
- A CLASS-D power amplifier with high efficiency and energy conservation
- 1X500W, 2X250W and 4X125W
- Contains 1/2/4 independent channels
- Each channel has 100V or 70V output
- Supports balanced or unbalanced audio input
- The ZS-1500/ ZS-2250/ ZS-4125 is cooled through forced air-cooling
- Able to automatically limit output voltage
ZS-1500/ ZS-2250/ ZS-4125 Functions and Features
This section describes the main functions of the ZS-1500/ ZS-2250/ ZS-4125:
- Main and Backup Power Supplies
- Power Supply Protection
- Overheating Protection
- Overload and Short-circuit Protection
- Fault Monitoring and Output
- Self-test Function
MAIN AND BACKUP POWER SUPPLIES
The ZS-1500/ZS-2250/ZS-4125 contain main and backup power supplies. The main power supply is
generally utilized, and the backup power supplies standby in case of a main power supply fault. In case of a
main power supply fault, the POWER indicator light on the ZS-1500/ZS-2250/ZS-4125 front panel and AC
FAULT indicator light turn on. The ZS-1500/ZS-2250/ZS-4125 outputs fault signals simultaneously and
automatically switches to the backup power supply for power. After the main power supply is returned to
normal, it supplies the power again.
POWER SUPPLY PROTECTION
In the case of a short circuit or other ZS-1500/ ZS-2250/ ZS-4125 fault, the main power supply input is
disconnected automatically.
OVERHEATING PROTECTION
When the temperature within the ZS-1500/ZS-2250/ZS-4125 reaches 45 C, the fans automatically start and
operate at the fastest speed. When the temperature is lower than 40 C, the fans stop.
When the temperature within the ZS-1500/ZS-2250/ZS-4125 exceeds 75C, the ZS-1500/ZS-2250/
ZS-4125 automatically stops producing signals and sends overheating protection signals to help identify the
faulty circuit. When the temperature has returned to normal (lower than 70C), the ZS-1500/ZS-2250/
ZS-4125 again performs normally.
OVERLOAD AND SHORT-CIRCUIT PROTECTION
When the ZS-1500/ZS-2250/ZS-4125 output experiences a short-circuit or is overloaded, the ZS-1500/
ZS-2250/ZS-4125 automatically disconnects the output, and outputs overload or short-circuit protection
signals until the faults are eliminated.
FAULT MONITORING AND OUTPUT
The ZS-1500/ZS-2250/ZS-4125 can monitor the main and backup power supply for instances of
undervoltage, overheating protection states, and overload or short circuit protection states. When the
ZS-1500/ZS-2250/ZS-4125 monitors any fault, the ZS-1500/ZS-2250/ZS-4125 outputs an general fault signal
until all faults are eliminated.

SELF-TEST FUNCTION
Press the Self-test button on the front Panel of ZS-2000M to start the self-test function. The ZS-2000M then
sends self-test signals to the amplifier, causing all indicator lights to turn on and all amplifiers to temporarily
stop operating. Upon the completion of the self-test, all functions return to normal.
