1.0 Introduction

1.1 Description

Use the D8125MUX Multiplex Bus Interface Module to connect multiplex points to the ZONEX bus on the following Bosch Security Systems control panels: new G Series (B9512G, B9512G-E, B8512G, B8512G-E), G Series (D9412GV4, D7412GV4, D7212GV4, D9412GV3, D7412GV3, D7212GV3, D9412GV2, D7412GV2, D7212GV2, D9412G, D7412G, D7212G), D9412, D7412, D7212, D9112, and D9124 with version

5.22 or greater firmware. Install the D8125MUX on

ZONEX 1 and ZONEX 2 (G Series, D9412, and D9112 only). The multiplex bus interface supports two independent multiplex buses; therefore, a fault on one multiplex bus does not prevent the other from operating normally.

The D8125MUX scans the multiplex points connected to it and reports the point status to the control panel.

Also available on the D8125MUX are auxiliary power terminals labeled Power A (+,-), Power B (+,-) that support remote devices requiring an uninterrupted source of power.

The B600 Retrofit (ZONEX) module is required to use the D8125MUX on the

3.2.2 Wiring Procedure

For Points 9 up to Point 127:

1. Connect the GND terminal of the D8125MUX to the control panel ZONEX COMMON terminal.

2. Connect the OUT terminal of the D8125MUX module to ZONEX IN 1.

3. Connect the IN terminal of the D8125MUX module to ZONEX OUT 1.

4. Connect the AUX terminal of the D8125MUX to ZONEX POWER + terminal.

For Points 129 up to Point 247:

1. Connect the GND terminal of the D8125MUX to the control panel ZONEX COMMON terminal.

2. Connect the OUT terminal of the D8125MUX module to ZONEX IN 2.

3. Connect the IN terminal of the D8125MUX module to ZONEX OUT 2.

4. Connect the AUX terminal of the D8125MUX to ZONEX POWER + terminal.

Do not connect more than one D8125MUX to ZONEX 1 (IN and OUT terminals) or ZONEX 2 (IN and OUT terminals).

Reversed polarity damages the D8125MUX. Make sure you wire the D8125MUX AUX and GND terminals to the control panel.

4.0 Program Multiplex Bus Points

Use the D5060 Programmer (Figure 4 and Table 3) to program multiplex bus points for the B9512G, B9512G-E, B8512G, B8512G-E, D9412GV4, D7412GV4, D7212GV4, D9412GV3, D7412GV3, D7212GV3, D9412GV2, D7412GV2, D7212GV2, D9412G, D7412G, D7212G, D9412, D7412, D7212, and D9112 control panels. In addition to programming points, the D5060 can also be used to program and read information from a D8125MUX.

The B600 Retrofit (ZONEX) module is required to use the D8125MUX on the B9512G, B9512G-E, B8512G, and B8512G-E control panels.

4.2 Programming

Table 4: Point Type Entry Code

4.2.1 Powering the D5060

Turn on the D5060 by pressing and holding the [1] key until the unit beeps. To turn the unit off, press and hold the [#] and [*] keys simultaneously until the unit beeps.

After 5 minutes of inactivity, the programmer powers down automatically to conserve power.

4.2.2 Programming Points

1. The D5060 shows the prompt Adr after it is

powered. This indicates that it is ready to begin programming.

2. If the multiplex device has no DIP switches,

connect the D5060 to the point to be programmed as shown in Figure 5 on page 7. If the multiplex device has DIP switches, program the device using its DIP switches.

If the multiplex device has no DIP switches, connect the D8125MUX and the multiplex device to be programmed to the D5060 for simultaneous programming (Figure 5). If the multiplex device has DIP switches, program the device using its DIP switches, and program the D8125MUX using the D5060 (Figure 6 on page 7).

3. Enter the point’s three-digit address. The address

must be between 1 and 255. Press [#]. The programmer shows tyP.

4. Enter the number corresponding to the point type

you are programming as shown in Table 4 and press [#]. The programmer alternately shows the address and the point type.

When you program for a multiplex smoke device by entering decimal value 4 or 5 Table 4, an 18-second timer starts counting. Do not disconnect the multiplex smoke device until after the timer counts down to zero.

1 Contact

2 Sensor (or single point module)

3 I/O module

4 Multiplex smoke without low

temperature

5 Multiplex smoke with low temperature

(0°C)

6 Dual point

5. Press [#] to program a point connected to the

D5060 and the D8125MUX (if connected), or press [1] to program the D8125MUX only. If the multiplex device has DIP switches, program the device using its DIP switches.

Press [*] at any time to return to a previous step in the procedure.

6. If the point is programmed correctly, the unit

beeps once and shows Adr, indicating it is ready to program the next point. If the point was not programmed correctly, the unit sounds a threebeep error tone and one of the following messages appears:

Err: The point was not programmed correctly. PnL: Communications with the D8125MUX failed.

7. Press [*] to clear the entry, or press [#] to

reprogram. If programming the D8125MUX and multiplex

device simultaneously and only one receives the program, the D5060 shows Adr. If having troubles with the point after installation, try programming the D8125MUX and multiplex devices separately.

4.2.3 Removing a Point from the D8125MUX

1. Apply power to the D5060 and connect the

programmer to the D8125MUX only.

2. Enter the address of the point you want to remove.

3. When prompted for a point type, press [0]. Refer

to Table 4. Then press [#].

4. Press [1] to remove the point.

5. If the point is programmed correctly, the D5060

beeps once and Adr appears.

4.2.4 Interrogation Mode

You can also use the programmer to read information from the D8125MUX and multiplex points. Refer to Section 4.1 Connecting the D5060 Programmer on page 6 to install the D5060.

4.2.4.1 Reading Information from the D8125MUX

1. To enter Interrogation Mode, press and hold [7]

and [9] simultaneously until the unit beeps.

2. The LED marked INTERROGATION MODE lights.

A.dr appears prompting you to enter a starting address.

3. Enter an address followed by [#]. The

Interrogation LED flashes.

4. Press [#] to read point information from the

D8125MUX at that address.

5. Press [4] to read the previous address information

from the D8125MUX.

6. Press [6] to read the next address information

from the D8125MUX.

If communication between the unit and the D8125MUX fails, the unit sounds a three-beep error tone and shows PnL.

7. Exit Interrogation Mode by pressing and holding

[*] until the unit beeps.

4.2.4.2 Reading Information from MUX Points

Disconnect all multiplex points from the D8125MUX and the multiplex bus before reading multiplex point information.

1. To enter Interrogation Mode, press and hold [7]

and [9] simultaneously until the unit beeps. The LED marked INTERROGATION MODE lights.

2. The display reads A.dr prompting you to enter a

starting address. Enter an address and press [#].

3. Press [1].

4. When t.YP appears at the keypad, enter the point

type of the multiplex point as shown in Table 4 on page 8 and press [#].

5. If a point responds to the address, the

programmer beeps once and rSP appears. If the point does not respond, the unit beeps three times and the display reads noP.

6. Exit Interrogation Mode by pressing and holding

[*] until the unit beeps.

4.3 Wiring the D8125MUX to Multiplex Points

Do not use shielded or twisted pair cable.

1. Connect Power A+ and Power A- on the D8125MUX

to multiplex devices that require uninterrupted auxiliary power. Refer to Figure 8 on page 9. Up to 200 mA is available at these terminals.

2. Connect MUX BUS A+ and A- on the D8125MUX to

the positive and negative bus wires of the multiplex points. The maximum allowable current on MUX BUS A is 75 mA.

Remove power from the D8125MUX before connecting or disconnecting multiplex
