Item Specications
RS485 serial
port
expansion
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● Supports four RS485 ports with the default communications
rate of 9600 bit/s.
● COM1–COM3 ports provide 12 V DC power.
● The power supply can be switched on or o and is on by
default.
POE
expansion
Supports two POE (GE) ports for expansion of the POE bus,
and supports network isolation and ring network.
AIDI
expansion
(RJ45)
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● Provides ve universal AIDI ports for connecting to sensors
such as smoke sensors, water sensors, and NTC sensors.
AIDI_1 to AIDI_3 are full-function AIDI ports, and AIDI_4 to
AIDI_5 are simplied AIDI ports without type identication.
● The power supply can be switched on or o and is on by
default.

(RJ45)
● Output voltage: 13–15 V DC (rated voltage: 14.5 V DC)
● One DO port. Supports active DO.
● The power supply can be switched on or o and is on by
default.
Fault isolation There are three groups of 12 V ports. A group has a maximum
current of 660 mA, a route has a maximum current of 800 mA,
and the maximum total current is 2 A.
Group 1: 12 V of the AIDI_1 and DO/12V ports
Group 2: 12 V of the AIDI_2, COM1/AIDI_4, and COM3/12V
ports
Group 3: 12 V of the AIDI_3 and COM2/AIDI_5 ports
Wireless
communicatio
n
Supports wireless communication that complies with
IEEE802.15.4.
4G Supports the 4G module. The ECC800-Pro supports short
message service (SMS) message sending and 4G
communication, is compatible with 3G (WCDMA)
communication, and provides a standard SIM card slot.
NOTE
The prerequisite for using a SIM card is that the site has signal
coverage.
