Output signal and LED indicators description
FD 330-4-
1 «VEGA» generates the following output signals:
- analogue signal with the following meanings:
a
) (2 ± 0,1) mA – «Failure»;
b
) (4 ± 0,1) mA – «Standard»;
c
) (18 ± 0,1) mA – «Fire»;
d
) (4.1 ± 0,1) mA – «Testing».
- digital signal via standard communication channel RS-485 with MODBUS protocol;
- actuating of the
«dry» contacts of two relays «Fire» and «Failure». Relays are
designed for switching current 1 A at a voltage of 30 VDC.
FD 330-4-
1 «VEGA» is equipped with LED indicators, displaying the current operation
mode of the detector.
Table 1 lists output signals, states of the relay contacts and indicator LEDs for FD
330-4-
