4.1.5 Locating a Particular Addressable Point
4.1.4 Identifying Addressable Points on a Circuit
If there are multiple expansion technologies
installed on the system, and you do not
know the expansion technology the point is
connected to, refer to Section 4.1.1 on
page 113 through Section 4.1.3 on page
115 before continuing.
If the addressable point you are locating is connected to a
D8125MUX Multiplex Bus Interface, remove power to the
D8125MUX whenever connecting or disconnecting
conductors to the MUX bus.
IMPORTANT: The rest of this procedure uses a half-split
troubleshooting approach. By answering the following
question, you divide the circuit in half to determine the half

panel before performing this procedure.
Refer to Section 4.1.2 Setting Up the
Control Panel on page 114.
of the circuit that contains the addressable point you are
locating.
By repeating the question, you divide the circuit in half
again to determine the half of the circuit that contains the
addressable point.
Repeat the following question as many times as necessary
1. on page 117Table 54 identifies which point
expansion technologies are installed at the site.
Label each data circuit wire, then disconnect all
but one data circuit from the affected expansion
technology.
until you reduce the circuit enough to identify the
addressable point.
During the rest of this procedure, if the procedure states to
“repeat the process and question above”, return to this
location in the procedure.
2. At the panel-wide keypad, press [MENU/ESC] to
view the main menu.
1. Locate the middle device on the circuit, then disconnect
the wires from the device that lead toward the end of the
circuit (away from the expansion technology).
3. Press [NEXT] until VIEW PT STATUS appears.
4. Select VIEW PT STATUS. The keypad displays
the number of points in the first area.

Using a panel-wide keypad (refer to Section 4.1.2 Setting
Up the Control Panel on page 114 for more information),

Press [NEXT] to scroll through the programmed points
until you see the addressable point you are looking for.
6. If the programmed point’s state is anything other
than “missing”, put the data circuit’s wire label
information in the Wire Label column of
Is the addressable point’s status “missing”?

The addressable point is between where you
disconnected the wires and either:

the on-board points are in use, they show

technology that is connected to the control
panel. It is not necessary to log the on-
board points in Table 54.

time the addressable point’s status was “missing”.
Reconnect the wiring, then repeat the process and

Reconnect the wiring, then repeat the process and question
above.
9. Repeat steps 2 through 8 until you have performed
these steps for each data circuit connected to the
expansion technology.
