CONNECTION WITH FIRE ALARM CONTROL PANEL
System can be connected with fire alarm control panel by dry contact or LPI-Modbus. Dry contact is used
for third party FAS without any protocol, LPI-ModBus is only used for Notifier's fire alarm control panel. Here
we introduce LPI-ModBus mostly.
Either ZS-2000M or ZS-4328IO can be connected with FAS through LPI-ModBus module, to realize the fire
alarm broadcasting function. This connection mode, that ZS-2000M is directly connected with the FAS
through LPI-ModBus module, is more suitable for the situation that the devices are concentratedly positioned.
The reason is: Because the devices has to connect with each other by RS-485, the limited distance RS-485
bus, when the equipment adopts distributed installation, using this method can lead to difficult wiring. If ZS-
4328IO is connected with FAS through LPI-ModBus module, can satisfy the application demands in the
distributed system. Only make sure ZS-4328IO and ZS-2000M are in the same network. ZS-4328IO can
receive the fire alarm signal automatically, and trigger ZS-2000M emergency broadcast according to the
linkages which are set in the Config software. This method can realize flexible linkage alarm function, and
support 2 types emergency broadcast: evacuation and alert.
System can be connected with Notifier's fire alarm control panel, and be compatible with:
- N-6000
- NFS2-3030
Connecting ZS-2000M with the Fire Alarm Control Panel
LPI-ModBus(Loop Peripherals Interface) is a SLC-ModBus converter. Digital Public Address and Voice Alarm
System is compatible with the V2.0 and V3.0 version of the LPI-ModBus module. The Converter provides a
communication link between FAS and the third party system that use the modbus/RTU communication
protocol. Each module supports max 6 ZS-2000M, 48 zones. The module power will be provided by the fire
alarm control panel. Please refer <LPI-ModBus converter User's Manual > to get more detail.
The RS-485 interface of LPI-ModBus module will be linked with ZS-2000M's RS-485 interface, the interface
definition is shown in Table 2.
As shown in Figure 36, LPI-ModBus is master, ZS-2000M is slave, and the slave address can be set in the
Config software. It is necessary that ZS-2000M, LPI-ModBus and FAS must be set respectively before
working.

Connecting ZS-4328IO with the Fire Alarm Control Panel
If ZS-4328IO is connected with the fire alarm control panel through the LPI-ModBus module, this
communication mode can achieve the fire alarm linkage between 32 ZS-2000M at most. In this
communication mode, ZS-4328IO is master, LPI-ModBus module is slave; ZS-4328IO supports up to 6 LPI-
ModBus module. The RS-485 interface of LPI-ModBus module will be linked with ZS- 4328IO's RS-485
interface (A1/B1) directly, the interface definition is shown in Table 2. If need to connect with multiple LPI-
ModBus modules, RS-485 bus wiring need to comply with the relevant standards, such as not star
connection, ensure the communication quality. The schematic diagram of connecting ZS-4328IO with the fire
alarm control panel through LPI-ModBus module is shown in Figure 37.
