OPERATION
The ZIC-4A contains four Class A circuits. Each circuit is rated at 3A at 24VDC and
has an input connected to the power source and an output where the NAC devices,
Municipal Tie, Releasing service and Leased Line remote monitoring device are
connected. The zone inputs are isolated from one another and are supervised for the
presence of power. This allows the use of different power sources with different
ground references. The zone output is supervised for open and short circuit condi-
tions while the zone is inactive and allows different combinations of output configura-
tions (Standard NAC, Releasing, etc.) per card. Each ZIC-4A card occupies any one
card slot in the CC-5 cardcage. The ZIC-4A also has the capability to detect ground
fault on its zone output as indicated by a diagnostic LED.
Controls and Indicators
The front panel of the ZIC-4A contains one reset switch, thirteen LEDs, and three
HNET address switches as shown in Figure 1.
A reset switch is located on the top of the front panel. Pushing the reset switch
re-initializes the ZIC-4A operation.
The LEDs follow the reset switch and their functions are defined as follows:
POWER
(Green)
Normally ON. When illuminated, indi-
cates that power for the ZIC-4A is
applied to the card.
CARD FAIL
(Yellow)
Normally OFF. When illuminated, indi-
cates that the card microprocessor has
failed.
CAN FAIL
(Yellow)
Normally OFF. When illuminated, indicates
that the CAN communication with the
ZIC-4A has terminated and the card goes
into degrade mode (applicable only when
card resides in a CAN network).
NOT
USED for FireFinder-XLS/Desigo Fire
Safety Modular/Cerberus PRO Modu-
lar applications.
HNET FAIL
(Yellow)
Normally OFF. When illuminated, indi-
cates that the HNET communication with
the ZIC-4A has terminated and the card
goes into degrade mode (applicable only
when card resides in the HNET network).
GND FAULT
(Yellow)
Normally OFF. When illuminated, indi-
cates that the ZIC-4A has detected either
a negative or positive ground fault on its
field wiring.
ZONE 1 ACTIVE
(Red)
Normally OFF. When illuminated, indi-
cates that Zone 1 is active.
TROUBLE
(Yellow)
Normally OFF. When illuminated, indi-
cates that the ZIC-4A has detected a
trouble on Zone 1 (open circuit or short
circuit).
ZONE 2 ACTIVE
(Red)
Normally OFF. When illuminated, indi-
cates that Zone 2 is active.
