Siemens CZM-1B6 Service manual

P/N 315-095355-9
OPERATION
The Model CZM-1B6 from Siemens Industry, Inc.,
is an MXL intelligent device that connects a single
zone of conventional devices to an analog loop.
The CZM-1B6 can power up to fifteen compatible
2-wire, ionization or photoelectric smoke detectors.
It can also monitor an unlimited number of shorting
devices such as waterflow switches, thermal
detectors, manual stations, etc.
Each CZM-1B6 can be assigned a 32 character
custom alphanumeric message. A multicolor LED,
visable through the cover plate, indicates the
condition of the circuit. This multicolor LED displays
red for alarm, yellow for trouble, and green for
normal operation (See Figure 1).
The CZM-1B6 supports Class A and Class B
wiring. The module uses one address on the
analog circuit. It does not require any mechanical
address programming. Use Model DPU Device
Programming Unit or FPI-32 Programmer/Tester to
program and test the module.
For additional information on the MXL/MXLV System,
refer to the MXL/MXLV Manual, P/N 315-092036.
SETTING THE MODULE ADDRESS
1. Using the DPU Device Programming Unit or
FPI-32 Programmer/Tester, plug the
programming cable into the programming
receptacle on the CZM-1B6 (See Figure 1).
2. Set the System address for the CZM-1B6 by
following the instructions in the FPI-32 Programmer/
Tester Manual, P/N 315-090077, or the DPU
User's Manual, P/N 315-033260, as appropriate.
NOTE: With FPI-32 Rev. 1.3 software, only 1=MXL
mode should be used when programming a
device.
INSTALLATION
Remove all system power before installation, first
battery and then AC. (To power up, first connect the
AC and then the battery.)
Electrical Connections
After you have set the CZM-1B6 address, connect the
field wiring. There are three basic connections to the
CZM-1B6. All terminals are power limited.
1. Initiating Devices (Figures 2, 3, and 4)
The CZM-1B6 supports one zone of initiating devices
in either Class A or Class B. The initiating devices are
connected to terminals 5–8 on the CZM-1B6 terminal
block. Figure 2 shows the Class A wiring. Figure 3
shows the Class B wiring.
Figure 4 shows the wiring for the PBA-1191 beam
detector. When the PBA-1191 is used, the 2-position
plug from jumper J1 must be removed. Follow the
steps listed below:
a. Remove the screw from the center of the
CZM-1B6 plastic cover and place it to one side.
b. Remove the circuit board and locate jumper J1.
c. Remove the 2-position plug from J1.

d. Reassemble the circuit board and plastic cover
using the screw that was removed in the first
step.
e. Be sure to use the correct end of line device with
the CZM-1B6 in this configuration.
The devices in the tables at the right are listed for use
with the CZM-1B6. Use up to fifteen detectors, any
combination of those listed. Only one PB-1191 or one
DF-1192, and no additional devices, can be connected
to a CZM-1B6. Detector operated accessories cannot
be used with the CZM-1B6. The model numbers listed
are the UL compatibility identifiers.
May use up to 15 detectors of any type.
* Only one PBA-1191 or one DF-1192, and no additional
devices, can be connected to a CZM-1B6.

2. Analog Loops (See Figure 5)
The CZM-1B6 communicates with the MXL via its
analog addressable loops. These loops may be on the
MMB or on the optional ALD-2I module. The analog
loops may be wired Class A or Class B. Figure 5
shows both wiring types, as well as the connections to
either the MMB or the MOM-4 when the ALD-2I
module is used.
3. 24 VDC Power (See Figure 6)
The CZM-1B6 receives its power from the CZM-1B6
power output on the MMB. This power is available on
TB5 of the MMB at terminals 9–12 or TB3 on the
PSR-1 on terminals 3-6. The power may be wired as
Class A or Class B. Since the CZM-1B6 monitors the
power at its screw terminals, you can star or T-tap the
power connection in the Class B configuration only.
Refer to Figure 6 for the wiring diagram.
