D9412GV2/D7412GV2 Operation and Installation Guide 8.0 On-Board Points

8.0On-Board Points

8.1Terminals 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 D9412GV2/D7412GV2 Program Entry Guide (P/N: F01U003636) for point programming options. The control panel also monitors the sensor loops for ground fault conditions if S4 is latched (ground fault detect enabled).

8.2Point 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.

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.

8.3Point 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.

Table 10: Point Parameters

Loop	Voltage Range
Open	Greater than 3.7 VDC, but less than 5.0 VDC.
Normal	Greater than 2.0 VDC, but less than 3.0 VDC.
Shorted	Greater than 0.0 VDC, but less than 1.3 VDC.
