3.15.1.2 Configuring the Monitoring Through the ESCM
The ESCM is an EMU that integrates the environment monitoring board, terminal blocks, and
DIP switches. The ESCM monitors the environment parameters such as smoke, water, door
status, wiring, temperature, and humidity of the device, and also provides extended monitoring
ports. This topic provides the basic information about the ESCM and describes how to configure
analog and digital parameters of the ESCM.
Prerequisites
l
The ESCM must be connected to the ESC port of the control board on the MA5616 through
a straight-through cable.
l
The setting of the hardware DIP switch on the ESCM must be the same as the configured
EMU subnode ID.
NOTE
For details about the settings of DIP switches, see ESCM EMU.
l
The sixth DIP switch on the ESCM must be set to on, which indicates that the baud rate is
19200 bit/s.
Context
l
The differences between an analog parameter and a digital parameter are as follows:
–
An analog parameter is a consecutive parameter, such as the temperature, voltage, and
current.
–
A digital parameter is a discrete value that indicates a state.
l
The ESCM requires an RS-485 serial port for data communication.
l
In the case of the ESCM, the system supports the following analog and digital parameters:
–
Analog parameters 0-1: invariably allocated by the system. You cannot modify any
parameter in these two analog parameters, except the upper and lower alarm thresholds.
–
Analog parameters 2-3: user-defined.
–
Digital parameters 0, 1, 8, and 9: invariably allocated by the system. You cannot modify
any parameter in these digital parameters, except the valid level.
NOTE
Digital parameter 9
Water_Alarm
: unavailable.
–
Digital parameters 2-7: user-defined.
