1.5.5 Output Signals
Outputs are available according to the default configuration or the wiring
options selected for the 40/40R detector. Determine the outputs for your
model according to Table 5.
The detector incorporates several types of output suitable to different
control systems:
• 0-20mA (stepped) with HART
• Relays (Alarm, Fault, Auxiliary)
• RS-485 Modbus
