ONNECTIONS

DigiplexNE uses GuardWall technology, a specialized encrypted

communication protocol to transmit data efficiently between the control

panel and all its modules simultaneously and continuously. Modules with

GuardWall technology connect anywhere on the 4-wire communication

network, which can support up to 127 modules. Connect in a star and/or

daisy chain configuration as shown in Figure 3-3 on page 10. The final

device on the communication network should not be more than 3000ft

(914m) from the control panel. To assign a detection device to a zone in the

control panel, see “Zone Programming” on page 16.

Before connecting a module to the communication network,

remove AC and battery power from the control panel.

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 5 on page 16).

3.17.1 Smoke Detector Installation (2-Wire)

PGM1 can be defined as a 2-wire

smoke detector input (see section 11.6).

Connect the 2-wire smoke detectors as

shown in Figure 3-8 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.

3.17.2 ESL CleanMe

Installation

The DigiplexNE control panel supports ESL smoke detectors that have the

CleanMe

feature. Connect ESL smoke detectors like the standard smoke

detectors shown in Figure 3-8. 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.

3.17.3 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 3-9. 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 Reset”

activation event (see section 11.1 on page

34) 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 5.2 on page 17), do not use the extra input (doubled

zone). For example, in this example input 13 cannot be used.

ONNECTIONS

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

3-10. 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 9.7 on page 31).
