The baud rate of the Flame-Monitor is fixed at 4800 bits per second. The format of the data is 8 data
bits, no parity and 1 stop bit. Due to the RS485 format, the communication format is considered half-
duplex. That is, only one user is permitted on the communication lines at a time.
The information contained in INPUTS and OUTPUTS represents the status of the interlocks and
relays respectively. For the INPUTS, a 1 in the interlock position defines the interlock as being on or
active where a 1 in any bit position in the OUTPUT register signifies the relay as being energized.
Refer to Fireye bulletin E-3001 for terminal designations
Table 3:
INPUTS
A ‘1’ in the opto-coupler position indicates the opto-coupler is on or interlock closed.
