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 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). 
8.2 
Point Sensor Loops 
When wiring the on-board points (Figure 10), install  
a 1 k
Ω
 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
8.3 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 k
Ω
 EOL resistor in 
place. 
Table 10: 
Point Parameters
