CONNECTING THE BUS IN NOISY ENVIRONMENTS
When installing the bus wires in proximity to high electrical interference such as neon lights, motors, high-voltage wiring, transformers, or if connecting the
bus 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
DigiplexNE incorporates an RTC directly on the PC board. The RTC will save DigiplexNE’s internal clock when both the AC and battery power have been
lost. After power is lost and then restored, DigiplexNE 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, DigiplexNE 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.
WARNING! 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.
