2.7.1 Verifying the Detector Wiring
The detector has five output wiring options within the Exde integral terminal
section of the enclosure. There are 12 terminals labeled 1-12.
For more information on the wiring options, see Wiring Instructions on
page 49.
For mA wiring options see Figure 10, Figure 11, Figure 12, and Figure 13.
For relay connection options see Figure 9.
Table 15 describes the function of each terminal for all the wiring options.
