4 REFERENCE & INSTALLATION MANUAL

2 INSTALLATION

2.1 RECOMMENDED INSTALLATION PROCEDURE

In order to facilitate installation, we recommend connecting the modules in

small groups and verifying the system after every group is connected,

instead of verifying the system only after all modules are connected.

Step 1: Install the control panel.

Step 2: Connect a small group of modules, including a keypad, to the

combus.

Step 3: Connect the battery and then connect the AC power. Enter section

[4000] to verify if all the connected modules’ serial numbers appear

(see section 11.19 on page 34). If all the modules appear in section

[4000], only the Clock Loss trouble and/or Bell Absent trouble

should appear on the keypad. Verify the connection if a module

does not appear in section [4000], or if a module trouble occurs.

Step 4: If another group of modules needs to be connected, disconnect AC

power and the battery, and then continue the installation by

following steps 2, 3 and 4.

Step 5: If modules were removed from the combus, enter [4005] to remove

them from the panel’s memory (see section 11.18 on page 34).

Step 6: Connect an LCD Keypad at various points farthest from the control

panel and use the keypad’s built-in Voltmeter to verify the combus’s

voltage (refer to the Digiplex/DigiplexNE LCD Keypad Reference &

Installation Manual).

2.2 LOCATION & MOUNTING

Before mounting the cabinet, push the five white nylon mounting studs into

the back of the cabinet. Pull all cables into the cabinet and prepare them for

connection before mounting the circuit board into the back of the cabinet.

Select an installation site that is not easily accessible to intruders and leave

at least 2" around the panel box to permit adequate ventilation and heat

dissipation. The installation site should be dry and close to an AC source,

ground connection and telephone line connection.

2.3 EARTH GROUND

Connect the zone and dialer ground terminals from the control panel to the

enclosure and cold water pipe or grounding rod as per local electrical codes.

For maximum lightning protection, use separate earth grounds

for the zone and dialer grounds (see Figure 2-3 on page 5).

2.4 AC POWER

Use a 16.5Vac (50/60Hz) transformer with a minimum 20VA rating to

provide sufficient AC power. For increased power use a transformer with a

40VA rating. For UL Listed systems, use model #BE156240CAA. For CSA

listed systems, use model #BE116240AAA. Do not use any switch-

controlled outlets to power the transformer. Connect the transformer as

shown in Figure 2-3 on page 5.

Do not connect the transformer or the backup battery until all

wiring is completed.

PLEASE NOTE: When powering up the DGP-NE96 control

panel (V1.02 or higher), the panel will begin a module scan to

verify if all the modules connected to the control panel are

operational. The scanning process will take between 30 and

120 seconds to complete depending on the number of

modules connected to the control panel. The module scan is

complete when the keypad begins to show the partition status.

Only after the module scan is complete will the control panel

be fully operational.

2.5 BACKUP BATTERY

To provide power during power loss, connect a 12Vdc 4Ah rechargeable

acid/lead or gel cell backup battery (YUASA model #NP7-12

recommended) as shown in Figure 2-3 on page 5. Connect the backup

battery after applying AC power. When installing, verify proper polarity, as

reversed connections will blow the battery fuse. For details on how to set

the Battery Charge Current to either 350mA or 700mA, see section 11.5.

2.5.1 Battery Test

The control panel conducts a dynamic battery test under load every 64

seconds. If the battery is disconnected, if its capacity is too low or if the

battery voltage drops to 10.5 volts or less when there is no AC, the “Battery

Trouble” message will appear in the Trouble Display. At 8.5 volts, the panel

shuts down and all outputs close.

2.6 AUXILIARY POWER TERMINALS

The auxiliary power supply can power the motion detectors, keypads and

other accessories in the security system. A fuseless circuit protects the

auxiliary output against current overload and automatically shuts down if

the current exceeds 1.1A. Auxiliary power will resume once the overload

condition has restored. For details on available output power, please refer

to Figure 2-3 on page 5. To calculate power consumption, see Calculating

Power Requirements on page 6.

2.7 BELL/SIREN OUTPUT

The

BELL+ and BELL- terminals power bells and/or other warning devices

that require a steady voltage output during an alarm. The bell output

supplies 12Vdc upon alarm and can support one 30-watt or two 20-watt

sirens. The bell output uses a fuseless circuit and will automatically shut

down if the current exceeds 3A. If the load on the

BELL terminals returns to

normal (≤3A), the control panel will re-instate power to the

BELL terminals.

When connecting sirens, please verify correct polarity as shown in Figure

2-3. PGM2 and PGM3 are relays rated at 5A each and can be used to

power bells and/or other warning devices by programming them as a bell/

siren outputs (see section 10 on page 31).

When the bell output is not used, the “Bell Absent” message

appears in the Trouble Display. To avoid this, connect a 1k

Ω

resistor across the bell output. UL Note: The keypads must be

programmed to beep with all troubles.

2.8 PROGRAMMABLE OUTPUTS

The control panel comes standard with

PGM1 to PGM3. When a specific event or

condition occurs in the system, a PGM can

be programmed to reset smoke detectors,

activate strobe lights, open/close garage

doors and much more. For details on how to

program the PGMs, refer to section 10.

PGM1 is 100mA (max.) normally open

output. PGM2 and PGM3 are 5A relay

outputs that can be normally open or

normally closed. If the current draw on

PGM1 is to exceed the current output, we

recommend using a relay as shown in

Figure 2-1. PGM1 can be programmed as a

2-wire smoke detector input (see section

2.17.1 on page 9 and section 10.6 on page 31).

2.9 KEYSWITCH CONNECTIONS (NOT VERIFIED BY UL)

Connect the keyswitches to the keypad,

control panel, or Zone Expansion Module's

hardwired input terminals as shown in Figure

2-2. Once a keyswitch is connected, it must be

assigned a keyswitch zone and its parameters

must be defined as described in Keyswitch

Programming on page 16.

2.10 ACCESS CONTROL CONNECTIONS

For all access control explanations and connection drawings, refer to

Access Control: System Features on page 38.
