CZM-1B6 Remote Conventional Zone Module
Instruction Manual

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 Figure1).
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.

NOTE:
Positive and negative ground fault detected at <30K ohms for terminals 5-8 on CZM-1B6.

Mechanical Installation

1. Mount the CZM-1B6 in a standard two gang electrical box. The box must have a depth of at least 3½ inches.
2. When the field wiring is connected (See above), press the CZM-1B6 into the box and fasten it with the four screws provided.
3. Attach a dress bezel if necessary, making sure that the ALARM LED is aligned with the hole in the bezel.
