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
page 113 through Section
115 before continuing.
You must correctly configure the control
panel before performing this procedure.
Refer to Section
Control Panel
Table 54
1. on page 117
expansion technologies are installed at the site.
Label each data circuit wire, then disconnect all
but one data circuit from the affected expansion
technology.
2. At the panel-wide keypad, press [MENU/ESC] to
view the main menu.
3. Press [NEXT] until VIEW PT STATUS appears.
4. Select VIEW PT STATUS. The keypad displays
the number of points in the first area.
The keypad you are using must have Panel
Wide scope. For more information, refer to
Section 4.1.2 Setting Up the Control Panel
on page 114.
5. If using a D1255 Keypad, press [ENT] twice. If
using a D1260 Keypad, press [Next][Status]. The
keypad shows the point status of the first
programmed point in the area.
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
on page 117.
When checking View Point Status, if any of
the on-board points are in use, they show
regardless of the point expansion
technology that is connected to the control
panel. It is not necessary to log the on-
board points in
7. Press [NEXT] repeatedly. Log each point that isn't
"missing" in Table 54
8. Disconnect the one connected data circuit, then
connect another data circuit that was connected to
this expansion technology.
9. Repeat steps 2 through 8 until you have performed
these steps for each data circuit connected to the
expansion technology.

4.1.5 Locating a Particular Addressable Point
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
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
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.
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).
2. Using a panel-wide keypad (refer to
Up the Control Panel
press [MENU/ESC] to view the main menu.
3. Press [NEXT] until VIEW PT STATUS appears.
4. Select VIEW PT STATUS. The keypad shows the number
of points in the first area.
Points can be located in more than one area. Ensure you
view points in all areas.
5. If using a D1255 Keypad, press [ENT] twice. If using a
D1260 Keypad, press [Next][Status]. The keypad shows
the point status of the first programmed point in the area.
6. Press [NEXT] to scroll through the programmed points
until you see the addressable point you are looking for.
Is the addressable point's status "missing"?
The addressable point is between where you
disconnected the wires and either:
- the expansion technology, or
- the location of the wiring you disconnected the last
time the addressable point's status was "missing".
Reconnect the wiring, then repeat the process and
question above.
The addressable point is between where you disconnected the
wires and either:
- the end of the circuit, or
- the location of the wires you disconnected the last time the
addressable point's status was not "missing".
Reconnect the wiring, then repeat the process and question
above.
