2. 1 RLY[4].7 = AZONES[18].5
The output label RLY[4].7 refers to the eighth output (.7) on the second group of outputs
on the second 4180 module ( [4] ). The status label AZONES[18].5 refers to the armed
status of the sixth zone (.5) of the zone group to which [18] has been assigned (Zones 137
- 144)—in other words, Zone 142. Table 19, “Output Designations,” shows which zones
are assigned to each bracketed number.
3. 1 TER16 = (THR = 1) OR (THR = 2)
The output label TER16 refers to Terminal 16 of the 4720. (THR, = 1) refers to the hour
that begins at 1:00 AM and ends at 1:59 AM. (THR, = 2) refers to the hour that begins at
2:00 AM and ends at 2:59 AM. If the current time falls within either of these two intervals,
the LED connected to Terminal 16 will light. Because these two time periods happen to be
consecutive, the LED will remain on continuously from 1:00 AM to 2:59 AM; it will not
go off between the two time intervals.
