Appendix A.3. Outputs
Electrical
Interface There are five output-wiring options. These options must be defined at
the factory per the customer order and cannot be changed at the
customer facility.
See Appendix B.1 for the wiring/terminal diagram for each wiring
option.
Unless otherwise specified, the default is Option 1. The wiring
arrangement is identified on the detector by the part number (see
Section 1.2 ).

Option 1: Power, RS-485, 0-20mA (Sink), Fault I Relay (N.C),
Alarm Relay, (N.O) (see Figure 24 )

Option 2 : Power, RS-485, 0-20mA (Source) and HART protocol,
Fault Relay (N.O), Alarm Relay, (N.O), (N.C)

Option 3 : Power, RS-485, 0-20mA (Source) and HART Protocol,
Fault Relay (N.O), Alarm Relay (N.O, N.C)

Option 4 : Power, RS-485, Fault Relay (N.C), Auxiliary Relay (N.O),
Alarm Relay, (N.O)

Option 5 : Power, RS-485, Fault Relay (N.O), Auxiliary Relay (N.O),
Alarm Relay, (N.O)

* In wiring options 3, 5 the relay is normally energized open during
normal operation of the detector. The relay is de-energized close
contact if a fault condition or low voltage situation occurs.
NOTE:
The Fault relay (in wiring options 1, 2, 4) is normally energized
closed during normal operation of the detector. The relay is de-
energized open if a fault condition or low voltage situation occurs.

0-20mA Current Output: The 0-20mA can be Sink or Source
according to the wiring option source (see Appendix B.1 ). The
maximum permitted
load resistance is 600Ω.
