1.5.5 Output Signals
Outputs are available according to the default configuration or the wiring
options selected for the 40/40I detector. Determine the outputs for your
model according to Table 7.
The detector incorporates several types of output suitable to different
control systems:
 0 – 20mA (stepped) with HART
 Relays (alarm, fault, auxiliary)
 RS-485 Modbus
