1.5.5 Output Signals
Outputs are available according to the default configuration or the wiring
options selected for the 40/40U and UB detector. Determine the outputs for
your model according to Table 6.
The detector incorporates several types of output suitable to different
control systems:
 0-20mA (stepped) with HART
 Relays (Alarm, Fault, Auxiliary)
 RS-485 Modbus
