8.0 On-Board Points

8.1

Terminals 11 to 22 Description

The control panel provides eight on-board points.
Each point functions independently and does not
interfere with the operation of the others. The control
panel monitors the sensor loops for normal, shorted,
or open conditions between an input terminal (11, 13,
14, 16, 17, 19, 20, or 22) and any of the point
common terminals (12, 15, 18, and 21). Programming
for the point determines how the control panel
responds to those conditions. Refer to the D7212GV3
Program Entry Guide (P/N: F01U170808) for point
programming options. The control panel also monitors
the sensor loops for ground fault conditions if S4 is
latched (ground fault detect enabled).
8.2

Point Sensor Loops

When wiring the on-board points (Figure 10), install
a 1 kΩ resistor at the far end of the sensor loop to
provide a reference for supervision. Dry-contact
sensing devices can be connected in series
(normally-closed) or in parallel (normally-open) to any
of these loops.

On-Board Points
The number of normally-open and normally-closed
detection devices each sensor loop can supervise is
limited only by the resistance on the loop. The total
resistance for the wire length and contacts, minus the
end-of-line (EOL) resistor, must not exceed 100 Ω.
8.3

Point Parameters

The condition of on-board Points 1 to 8 is determined
by measuring the voltage across the point input
terminal and one of the common terminals. The
sensor loops must be connected and the 1 kΩ EOL
resistor in place.
