DGP-NE96 Control Panel 7
2.16 Combus Connections
Modules can connect anywhere on the 4-wire combus, which can support
up to 127 modules. Connect in a star and/or daisy chain configuration as
shown in Figure 3 on page 3. The total distance of all runs of wire cannot
exceed 914m (3000ft). For example, if ten runs of wire measuring 305m
(1000ft) each are connected to the control panel, the total distance would
be 3048m (10,000ft), which exceeds the system’s capacity. To assign a
detection device to a zone in the control panel, see
Zone Programming on
page 10.
Before connecting a module to the combus, remove AC and
battery power from the control panel.
2.16.1 Connecting the Combus in Noisy Environments
When installing the combus wires in proximity to high electrical
interferences such as neon lights, motors, high-voltage wiring,
transformers, or if connecting the combus across separate buildings, you
must use shielded cables. Connect the shielded cable as detailed below:
Within the Same Building: Strip the outer jacket at one end of the
shielded cable to expose the shield and connect the shield to the control
panel ground (not the dialer ground), while leaving the shield at the other
end of the cable open (floating).
Across Separate Buildings: Strip the outer jacket at one end of the
shielded cable to expose the shield. In the same building that houses the
control panel, connect the exposed shield to a cold water pipe or any other
earth ground available, while leaving the shield at the other end of the cable
open (floating). The same configuration applies for any subsequent
building.
2.17 Fire Circuits
Connect the smoke detectors using any of the following methods. Assign
the smoke detectors connected to the control panel or zone expansion
input terminals to a zone and define the zone's parameters as a Fire Zone
(see section 4 on page 10).
2.17.1 Smoke Detector Installation (2-Wire)*
PGM1 can be defined as a 2-wire
smoke detector input (see section
10.6). Connect the 2-wire smoke
detectors as shown in Figure 8 using a
1k
Ω
EOL resistor. If a line short
occurs or the smoke detector
activates, whether the system is
armed or disarmed, the control panel
will generate an alarm. If the line is
open, the “Zone Fault” trouble
indication appears in the Trouble
Display and the report code is sent to
the monitoring station, if programmed.

UL Note: Not to be used with UL Listed systems.
2.17.2 ESL CleanMe
®
Installation
The DGP-NE96 control panel supports ESL smoke detectors that have the
CleanMe
®
feature. Connect ESL smoke detectors like the standard smoke
detectors shown in Figure 8. Avoid connecting more than 20 ESL smoke
detectors. When an ESL smoke detector sends a CleanMe signal, the
control panel will generate a Zone Fault trouble and, if programmed, will
transmit the Fire Loop report code to the monitoring station. The trouble will
be cleared if there is no CleanMe signal for 255 seconds. If an alarm
occurs, the trouble will be cleared until it is detected again.
2.17.3 Smoke Detector Installation (4-Wire)
Recommended: System Sensor model
2112/24D smoke detectors. Connect the
4-wire smoke detectors and a relay as
shown in Figure 9. To comply with UL955,
install the 4-wire smoke detectors with 18
gauge wire. If power is interrupted, the
relay causes the control panel to transmit
the Fire Loop Trouble report programmed
in section
[2906] .
To reset (unlatch), connect the smoke
detector’s negative (-) to a PGM. Then
program the PGM with the “Smoke
Detector Power Reset” activation event
(see section 10.1 on page 29; Event
Group #067, start # 004, end # 004) to
interrupt power to the smoke detector for
four seconds when the
[
CLEAR
] and
[
ENTER
] keys are pressed and held for two
seconds.
If ATZ is enabled (see see section 4.2 on page 11), do not use the
extra input (doubled zone). For example, in this example input
13 cannot be used.
2.18 Telephone Line Connections
Depending on the installation, the telephone lines can be connected directly
to the control panel or through a CA38A or RJ31 as shown in Figure 10.
The secondary telephone line terminals (optional) can be used as a backup
telephone line. If the Event Call Direction process fails and the control panel
is unable to communicate with the monitoring station through the main line,
the control panel will switch to the second line and repeat the Event Call
Direction process (see section 8.8 on page 25).
UL Note: Installer must verify line seizure after every installation
