SLC®
Series 5 Carrier System power shelf. An external
ground must be connected to output-common to access the alarm. Refer to Figure 2-15
(Releases 6 and 7) or Figure 2-17 (Releases 8, 9, 11 and 13).
2. The external inputs to the miscellaneous (environmental) discretes is a contact closure
and is connected to the DDM-2000 by two leads (wires). For each of the miscellaneous
(environmental) inputs that are being used, connect one lead to input-common (TLMI-C)
and the other lead to the appropriate alarm designation (TLMI-#).. Refer to Figure 2-15
(Releases 6 and 7) or Figure 2-17 (Releases 8, 9, 11 and 13).
