MS-1 and MS-2

MS-1 and MS-2 adapter modules are digital electronic devices designed for interfacing of the addressable receiving and control devices, indication blocks, and remote control panels with a computer.
Power supply from PC USB
The quantity of outputs for interface connection:
a) for MS-1:
RS-485
electrically isolated USB;
b) for МС-2:
RS-485,
electrically isolated USB.






RS485 interface cable length, no more than 1000 m
USB interface cable length, up to
2 m
Module overall dimensions, no more than
84х125х37 mm
Weight, no more than 200 g
Operating temperature range from 0 to plus 40°С
Average service life 10 years

MS-1 and MS-2 adapter modules provide the following:
  • integrated addressable control and indicating panels connection via RS-485 interface to USB port of the computer to ensure the system control and monitoring;
  • the system connection with cross-connection between control and indicating panels built in one RS-485 network to the computer;
  • LED communication indicating between the panels and the computer.
MS-1 and MS-2 functions are identical. Difference between MS-1 and MS-2 modules is in the quantity of the outputs for interfaces connection:

MS availability time after connection is - no more than 1 second.

Modules power supply is realized via PC USB interface.­ On the front side of the device, there are LEDs intended to display the current state of the adapter module. 

LED communication:
  • when the USB is connected, but there is no exchange with the FireSec monitoring software, the LED is blinking with a frequency of 1 Hz;
  • when there is exchange with the PC, the LED is blinking with a frequency of 5 Hz;
  • when the communication with the PC is lost, the LED produces single flashes with a period of 2 seconds.
LED indicators of RS-485 “1” and “2”:
  • when there is no exchange with the PC, the LEDs are off;
  • when there is exchange with the PC, the LED is blinking at a rate of 10 Hz.
