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 General Instructions for Electrical Wiring on page 49
for the wiring/terminal diagram for each option.
Unless otherwise specified, the default is Option 1. The
wiring arrangement is identified on the detector by the
part number (see Model and Types on page 2).
 Option 1: Power, RS-485, 0-20mA (Sink), Fault I
Relay (N.C), Alarm Relay, (N.O) (see Figure 8).
