NI-2100/3100/4100 - Hardware Reference Guide
Timekeeper
The Controllers use a combination lithium battery and clock crystal package called a
Timekeeper
. Only one
Timekeeper
unit is
installed within a given NI controller. The battery can be expected to have up to 3 years of usable life under very adverse conditions.
Actual life is appreciably longer under normal operating conditions.
This calculation is based on storing the unit without power in 50° C (120° F) temperature until battery levels are no longer
acceptable.
The part number for a replacement battery is
57-0032
.
CAUTION:
RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO
THE INSTRUCTIONS
NI-2100
The NI-2100 (
FG2105-04
) is ideal for control and automation of medium-sized rooms and multi-room applications. The NI-2100
has 64MB of onboard RAM and is Device Discovery enabled to simplify programming by standardizing device and function
definitions, default touch panel button assignments, and control and feedback methods.
