DF8045/46 front panel
Three dip-switches, located on the front panel of the DF8045/46 (refer to Fig. 24),
are used to set the module’s I
2
C address. Although there are 8 possible selections,
from 0 to 7, the valid I
2
C address can range from 0 to 2 (single unit) or 0 to 5 (dou-
ble unit). Refer to Annex B on page 36 for a complete list of the valid DF8000 con-
figurations.
Furthermore, 8 LEDs on the same front panel indicate the physical state of the in-
dividual inputs: the green LED is on when the input is in normal operation, the red
LED is on when an alarm condition is detected, in case of tamper (cable short or
open) both LEDs are on. These devices can be disabled from the CPU module to
reduce power requirements (see 4.1 and 10.4).
