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.
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
page 6 and press [#].
5. If a point responds to the address, the

Installing and Wiring the
D8125MUX to the Control Panel
The D8125MUX is installed in the control panel
enclosure and is connected to either Zonex 1 or
Zonex 2 on the control panel.

D8125MUX | Operation and Installation Guide | 3.0
1. Align the D8125MUX with any of the three
mounting locations shown in
Then fasten the module with the three mounting
screws provided.
2. Remove AC and DC power from the control
panel.
3. Connect 12 V from the D8125MUX to Zonex
Power +, Terminal 24, on the D9412GV2,
D7412GV2, D7212GV2, D9412G, D9412, and
D9112 (Terminal 3 on the 7412G, D7212G,
D7412, and D7212) as shown in
page 8.
4. Connect IN on the D8125MUX to Zonex Out 1,
Terminal 28 (or Zonex Out 2 Terminal 26) on the
control panel.
5. Connect OUT on the D8125MUX to Zonex In 1,
Terminal 27 (or Zonex In 2 Terminal 25) on the
control panel.
6. Connect GND on the D8125MUX to Zonex
Common, Terminal 23, on the D9412GV2,
D7412GV2, D7212GV2, D9412G, D9412, and
D9112 (Terminal 9 on the D7412G, D7212G,
D7412, and D7212).
7. Connect Power A + and Power A - on the
D8125MUX to multiplex devices that require
auxiliary power. Up to 200 mA are available at
these terminals.
8. Connect MUX BUS A + and A - on the
D8125MUX to the positive and negative bus wires
of the multiplex points.
9. When using Loop B, connect Power B (if
applicable) and MUX BUS B on the D8125MUX
to the power and bus wires of the multiplex
points. Power B+ and B- also have up to a 200
mA capacity. Observe correct polarity.
Table 3 on
Figure 6 on page 8.
Ensure the D8125MUX is not powered
before connecting or disconnecting
multiplex devices. Connecting or
disconnecting a multiplex device while the
D8125MUX is powered causes the
multiplex device address setting to
reprogram or scramble.
