Installation Instructions
Model ZC1-8B Zone
Control Card Module
INTRODUCTION
The Model ZC1-8B Zone Control Card from Siemens Industry, Inc. has one channel
of audio input and eight audio zone outputs. The module name indicates the
following information:
ZC1 — Zone Card with one audio input
8B — 8 Zone Class B (Style Y) outputs
The one channel of either 25.2V or 70.7V RMS amplified audio input connects to
this card through the OMM-1/-2 screw terminals next to the OMM-11-2 edge
connector.
All ZC1-8B output zone circuits are supervised, protected by fuses, and used
for Class B (Style Y) operation only. Use the ZC1-8B module with 3.15A fuses,
P/N 545-696401, for 25V speaker and strobe circuits. The eight available zones
may be all speaker, all strobe, or a mix of the two types. The eight zones may
be divided into groups of 3, 3, and 2, with each group used as either speaker
or strobe circuits. A separate amplifier may feed each group for speaker
application. Refer to Figure 6 for more information.

Use the ZC1-8B with 1.6A fuses, P/N 105-250703, or 2.0A fuses, P/N 545-696402,
for 70V speaker circuits only. The ZC1-8B occupies one of eleven subaddresses
of the OCC-1 Output Control Card module. When installing a zone control
module, use the CSG-M (AccuLINK) configuration printout to locate the address
of each zone control card. Use switch S1 to set the unique address for up to
11 zone control cards as described in Table 2.
Refer to the PLC-4 Instructions, P/N 315-093312, for additional wiring
information.
For additional information on the Voice Sys-tem, refer to the MXLV Manual,
P/N 315-092036.
INSTALLATION
Remove all system power before installa-tion, first battery and then AC. (To power up, connect the AC first and then the battery.)
-
Remove the card from its protective bag. Do not touch the gold edge of the board.
-
Refer to the function section of the CSG-M configuration printout for the address of the module.
-
Set the card address on switch Si using dipswitches SW1—SW4. (SW5 is not used at this time.)
a. Refer to Figure 1 for the location of S1.
b. Refer to Table 2 for switch settings (See Note below). -
The ZC1-8B comes with 1.6A fuses, P/N 105-250703, installed at the factory.
For 25V installations, remove the 1.6A fuses, Fl — F8, and install the 3.15A
fuses. P/N 545-696401, found in the installation kit with the user key and the
end-of-line resistors.
X = SWITCH CLOSED OR ON, 0 = SWITCH
OPEN OR OFF
NOTE: To open a dipswitch, press down on the side of the dipswitch marked
OPEN. To close a dipswitch, press down on the side of the dipswitch opposite
the side marked OPEN.
To open a slide switch, push the slide to the side opposite the side marked
ON. To close a slide switch, push the slide to the side marked ON.
Do NOT install the card in its edge connector until ALL OMM-1/-2 field wiring
is completed and checked for shorts, opens, and other faults. Refer to the
Wiring Checkout Chart. Replace the card in its protective bag if the wiring is
not complete. Find the user key provided in the installation kit with the
ZC1-8B board. Place the user key in the OMM-1/-2 edge connector for the ZC1-8B
as shown in Figure 2. See Figure 3 for the exact location of the key for this
module. This prevents installation of any other card type in the ZC1-88 slot.
Two other keys already installed in the OMM-1/-2 prevent reverse installation
of the card in the OMM-1/-2 edge connectors. (See Figure 3.) Place the card in
its card edge connector correctly. The components on the board must face the
22-position terminal block where the wiring is termi-nated. Press the card
firmly in place to be sure it is seated properly in the edge connector.
CAUTION At all times handle all plug-in cards with extreme care. When
inserting or removing a card, be sure the position of the card is kept at
right angles to the OMM-1 /-2 hoard. Otherwise, the plug-in card can damage or
displace other components.

WIRING
Refer io Figures 4, 5, and 6.
All wiring must comply with national and local codes.
Terminate all unused outputs with an EOL resistor. Some signal is lost in the
zone wires due to line resistance. Refer to the Speaker Application Guide
(http://www.buildingtechnologies.usa.siemens.com/Supporti?languagecode=en.
Then click on Application Guide in Fire Safety) for further information. A
reduc-tion in load reduces the loss. Use the largest wire size possible for
the minimum loss.

Any UL listed Fire Protective Signaling Speaker rated 25/70.7V RMS may be
connected to this cir-cuit. See P/N 315-096363 for compatible combina-tion
speaker strobe models.
