INTRODUCTIONThe Model ZIC-4AC from Siemens Building
Technologies, Inc., is a zone interface card that
provides notification appliance circuits (NAC) for
the system. It has 4 outputs that can be
configured for Class A or Class B and control of
audible and visual notification appliances such as
speakers, strobes, horns, bells, etc.
Each zone can be configured independently for
different usages as programmed in the Zeus tool
and can be controlled automatically by program
logic or manually using the PMI. During the initial
power-up condition, each zone on the ZIC-4AC is
configured as a steady NAC, Class A configuration
with 2A current limit. The ZIC-4AC then sends a
message to the PMI indicating that it is
unconfigured.
The ZIC-4AC supports one or two channel bulk
amplification as well as synchronized and nonsynchronized strobes. This selection is available in
the Zeus tool under the detail properties for each
ZIC-4AC circuit. Synchronization across multiple
ZIC-4AC cards is automatic as a part of the
system operating characteristics.
FeaturesZIC-4AC features are as follows:
•Zones can be configured independently for
audio or strobe use
•Zones can be configured independently for
Class A or Class B
•Can have independent input sources for each
output
•Zone input voltage supervision
•Zone output supervision
•Intelligent self-restoring power limiting
•Coded signal synchronization capability
•Card level Ground Fault detection
•Communicate CAN protocol
•Uploadable firmware update
•Ability to pass through up to 4A per circuit

OPERATIONThe ZIC-4AC contains four Class A circuits. Each circuit is rated at 4A at
24VDC and has an input connected to the power source and an output where
the NAC devices 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 conditions while the zone is inactive and
allows different combinations of output configurations (Standard NAC or
Speaker) per card. Each ZIC- 4AC card occupies any one card slot in the CC5/CC-2 cardcage. The ZIC-4AC also has the capability to detect ground fault
on its zone output as indicated by a diagnostic LED.
Strobe unsynchronized:
Input 1is connected directly to output 1, output is ON steady . Same for In/Outputs 2, 3 and 4
Strobe synchronized:
Input 1 is connected directly to output 1, Output is ON for about 1 second,
then a ZIC-4AC onboard relay switch output polarity (+24V is now GND and
GND is now +24V). This will cause the strobes to flash. All ZIC-4AC outputs
configured as strobe sync will switch output polarity at the same time, also
outputs from other ZIC-4AC. Same for In-/Outputs 2, 3 and 4
Bulk amplification 1 channel:
Input 1is connected directly to output 1, output is ON steady. Same for In/Outputs 2, 3 and 4
Bulk amplification 2 channel:
This mode provides the possibility to choose between two different signal
for one speaker line. Signal one (A) has to be connected to input 1. Signal two
(B) has to be connected to input 2. A ZIC-4AC onboard input relay switches
automatically the correct signal to the outputs 1 and 2. The functionality is
identical for IN-/Output pairs 3 and 4.
Controls and IndicatorsThe Front Panel of the ZIC-4AC contains one reset switch, thirteen LEDs,
and three CAN 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-4AC operation.
The LEDs follow the reset switch and their functions are defined as follows:
POWER(Green)Normally ON. When illuminated,
indicates that power for the ZIC-4AC is
applied to the card.
CARD FAIL(Yellow)Normally OFF. When illuminated,
indicates that the card microprocessor
has failed.
CAN FAIL(Yellow)Normally OFF. When illuminated,
indicates that the CAN communication
with the ZIC-4AC has terminated and
the card goes into degrade mode
HNET FAIL(Yellow)NOT USED

GND FAULT(Yellow)Normally OFF. When illuminated,
indicates that the ZIC-4AC has
detected either a negative or positive
ground fault on its field wiring.
ZONE 1 (2, 3, 4) ACTIVE(Red)Normally OFF. When illuminated,
indicates that Zone 1 (2, 3, 4) is active.
TROUBLE(Yellow)Normally OFF. When illuminated,
indicates that the ZIC-4AC has
detected a trouble on Zone 1 (open
circuit or short circuit).
Three rotary dial switches at the bottom of the front panel are used to set
the CAN network address of the ZIC-4AC.
PRE-INSTALLATIONThe following components must be set prior to inserting the card to the CC-5
(refer to Figure 2):
S1: Not used
Switch position has to be off
(upper position)
S2: Not used
All four switch positions have to
be off (left position)
S3: Reset Switch
Momentarily Closed switch that
when pressed will initiate a hard
reset to the ZIC-4AC (similar to a
cold boot).
S5: Input Power Select
This switch selects the source of
voltage input to power the ZIC-
4AC. BP Power indicates that
the input is derived from the
backplane of the CC -2/CC-5 and
EXT Power indicates that the
input is derived from E5/E11
terminal of the CC-2/CC-5,
normally connected to nonpower limited output of the PSC-
12/PSX-12. It is important to take
into account the source of the
voltage during power
calculations.

S4, S6, S7: Network Address Switch
Set the two-digit CAN network address for the ZIC-4AC using the three rotary
dial address switches located near the bottom of the front panel. (Refer to
Figure 1 for the location of the switches.) The address for the ZIC-4AC must
be the same as the address selected for it in the Zeus Programming Tool. To
set the address, turn the pointers on each of the three dials to the numbers
for the selected address. For example, if the address is 23, set the pointer for
the HUNDREDS dial to “0”, set the pointer for the TENS dial to “2”, and set
the pointer for the ONES dial to “3”. The range of allowable addresses is
from 001 to 099 (leading zeros must be used).

A24205-A334-B828 (English), or the Zeus self -help index for more information.
Disconnect BATTERY and AC prior to working on equipment
All field wiring to the ZIC-4AC is
connected to the terminal blocks of the
CC-5/CC-2 card cage slot in which it is
installed (Refer to Figure 3).
To Connect External Wiring
1.Loosen the screw of the
terminal by turning it
counterclockwise.
2.Insert the wire into the side of
the terminal block.
3.Tighten the screw of the
terminal block by turning it
clockwise.
The top terminals (1 through 8 and 9
through 16) are connected to the
notification appliance devices such as
bells, horns, strobes, speakers, etc. Each
zone has four terminal connections: (+),
Class A (+), (-), Class A (-). These
terminals are power limited.
The bottom terminals (17 through 24) are
Figure 3
ZIC-4AC Wiring The 24VDC Power
Lines To The ZIC- AC Slot In The CC-5
connected to the input power source of the NAC devices. Each zone has a (+)
terminal and (-) terminal. These terminals are not power limited.
Care must be taken when installing the zone input and zone output field
wiring to prevent possible cross wiring. This can cause severe damage to
the system when powered up or when zone is activated.
The screw terminals can accommodate one 12 -24 AWG (Ø 0.5mm –
2.5mm2) or two 16-24 AWG (Ø 0.5mm – 1.5mm2).
If the total output of all 4 zones exceeds 12 amps, a single PSC-12C cannot
be used to supply the ZIC-4AC. Refer to the PSC-12C Installation Instructions
A24205-A334-B798 for information when the total system load exceeds 12 amps.

24V Standby CurrentSame as 24V Back Plane Current
The 24V backplane current is dependent on the usage and wiring type of
each ZICCkt of the ZIC-4AC. Listed below are the required current draws for
each zone and wiring type.
ZIC-4AC Backplane Current Requirement

Requirement
Class A Current
Requirement
Not Used00
Strobe – Sync.17mA6mA
Strobe – Unsync.17mA6mA
Speaker Zone34mA6mA
ZIC-4AC Module Current = 89mA
To calculate the maximum backplane current, the following equation should
be used:
ZIC-4AC Module Current+ Zone 1 Usage Req.(See Table above)
+ Class A current (if Class A)
+ Zone 2 Usage Req.(See Table above)
+ Class A current (if Class A)
+ Zone 3 Usage Req.(See Table above)
+ Class A current (if Class A)
+ Zone 4 Usage Req.(See Table above)
+ Class A current (if Class A)
Example 1: If a ZIC-4AC has the following ZICCkt setting:
ZICCkt#1 - Speaker Zone Class A
ZICCkt#2 - Speaker Zone Class A
ZICCkt#3 - Speaker Zone Class A
ZICCkt#4 - Speaker Zone Class A
By applying the equation above, the maximum backplane current requirement
for this card will be determined.
6. Maximum line resistance is
dependent upon the maximum
current draw of connected
notification appliances when
activated. The field wiring
resistance cannot exceed the
maximum line resistance specified
for any given NAC current draw.
(See Table)
6. For two channel speaker application, the channel with higher priority (EVAC) must be connected to inputs 2/4 and the
channel with the lower priority (ALERT) must be connected to inputs 1/3 to ensure proper switching operation of the ZIC-
4AC.
7. Verify that P1 - P4 are in the proper location for speaker application.
