Digiplex -EVO- - 64 - Programming Guide

STEP 2: If the Grand Total is less than 700mA, go to step 3. If the value is greater, you will require an external power supply (see External Power Supply

Connections drawing on page 62) to provide the additional power needed. Proceed with step 3 and refer to the example (Sample Power

Requirement Calculations drawing) on page 62.

STEP 3: Due to the degradation of a power signal over long distances (if this were the case, we recommend connecting a Paradox Power Supply

Module, DGP2-PS17), EACH length or run of wire in the system can support only a specific number of milliamps (mA). Using Table 6,

determine how many milliamps each length of wire can support. Please note that the total number of milliamps (mA) can never surpass 700mA.

Connecting the Combus in Noisy Environments

When installing the combus wires in proximity to high electrical interference 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 to any subsequent building.

Built-in RTC

Digiplex EVO panels incorporates an RTC directly on the PC board. The RTC will save the control panel’s internal clock when both the AC and battery power

have been lost. After power is lost and then restored, the control panel will verify with and then retrieve the time from the RTC. The control panel will verify

and compare its time with the time stored in the RTC every hour. If the times are different, the control panel will reset its internal clock to the time saved in the

RTC. The RTC uses a 3V lithium battery (CR2032) with a battery life of 11 years. Change the battery as shown below:

Reprogram the control panel’s clock after changing the battery.

Danger of explosion exists if the lithium battery is incorrectly replaced. Replace only

with the same or equivalent type recommended by the manufacturer. Dispose of used

batteries according to the manufacturer’s instructions.

Do not connect a DGP2-TM1 Time Module to the "mem key" connector. Connecting a

DGP2-TM1 will create time errors within the panel and features that use the control

panel's internal clock (ex.: Auto-arming) will not function correctly.
