2.3.5 DI interface
The Gazelle S1020i-GL DI interface adopts the 5-pin Phoenix connector (with spaces of 5.08
mm) or the 3-pin Phoenix connector (supported by the GazelleS1020i-4GF-8GE-GL only),
which is connected with a related device for inputting external digital signals, thus monitoring
external environment alarms.
Figure 2-15 shows the DI interface on the Gazelle S1020i-4GF-16GE-GS and Gazelle
S1020i-4GF-8GE-GS.
Figure 2-16 shows the DI interface on the Gazelle S1020i-12GF-16GE-GS.
