28 Connecting the Detector
7 Verify the wiring. Improper wiring may damage the detector.
8 Check the wires for secure mechanical connection and press them neatly
against the terminal to prevent them from interfering while closing the
back cover (figure 7).
9 Place and secure the detector’s back cover by screwing the three (3)
socket-head-screws in the Cover Bolts (Figure 4).
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.
Table 13 describes the function of each terminal for all the wiring options.
