A.3.1
Electrical Interface
There are 5 output wiring options. These options are defined at the factory per
the customer order and cannot be changed at the customer facility.
General Instructions for Electrical Wiring
on page 61 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
on page 16).
