Model ZIC-4AC

Zone Interface Card (500-035850 / S24235-B110-A2)

INTRODUCTION The 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 non-

synchronized 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.

Features ZIC-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

OPERATION The 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 CC-

5/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 Indicators The Front Panel of the ZIC-4AC contains one reset switch, thirteen LEDs,

and three CAN address switches as shown in Figure 1.

AReset 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

A24205-A334-B827

P/N 315-035850-2

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-INSTALLATION The 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 non-

power 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).

Wiring

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

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 (Ø0.5mm –

2.5mm2) or two 16-24 AWG (Ø0.5mm – 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.

INSTALLATION The ZIC-4AC plugs perpendicularly into one slot in the CC-5 card-cage via two

96-pin DIN connectors and can occupy any slot in the card cage. (Refer to

Figure 4.)

Insert the ZIC-4AC card into the card guides right side up (lettering on the

front panel is legible)

Slide the card in until the card edge connectors contact the receptacles on

the motherboard.

Verify that the DIN connectors of the card and the card-cage aligned properly.

The card can only plug in one direction to the card cage, if it does not align,

DO NOT FORCE the card.

Place thumbs on the front panel adjacent to the captive screws and gently

apply even pressure on the card until the connectors seat in the receptacles

on the motherboard.

Secure with the captive screws.

ELECTRICAL RATINGS

24V Back Plane Current see NOTE below

Screw Terminal 24V Current Total Device Current

6.2V Back Plane Current 0

24V Standby Current Same 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

Zone Usage Output Current

Requirement

Class A Current

Requirement

Not Used 0 0

Strobe – Sync. 17mA 6mA

Strobe – Unsync. 17mA 6mA

Speaker Zone 34mA 6mA

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.

Maximum Backplane Current =

89 + (34 + 6) + (34 + 6) + (34 + 6) + (34 + 6) = 249mA (worst case)

A24205-A334-B827

Example 2: If a ZIC-4AC has the following ZICCkt setting:

ZICCkt#1 - Strobe Unsync., Class A

ZICCkt#2 - Strobe Sync., Class A

ZICCkt#3 - Strobe Sync., Class B

ZICCkt#4 - not used

Maximum Backplane Current =

89 + (17 + 6) + (17 + 6) + (17 + 0) + (0 + 0) = 152mA
