9.0Off-Board Points

9.1Point (Zonex) Bus: D9412GV2 Terminals and D7412GV2 Terminals

9.1.1POPIT Modules

The D9412GV2 can use point of protection input transponder (POPIT) modules to provide a maximum of 238 off-board points, bringing the total number of points the D9412GV2 can monitor to 246. The D7412GV2 provides up to 67 off-board points, bringing the total number of points the D7412GV2 monitors to 75. Each off- board point requires a POPIT Module.

9.1.2POPEX Modules

POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data expansion loops connect to a D8125 Point of Protection Expander (POPEX) Module. POPEX Modules have power and data connections to the point bus on the control panel (Table 11).

Table 11: POPEX Modules

Model	Power	Data
D9412G	Terminals 23 and 24	Terminals 25 and 26
		or
		Terminals 27 and 28
D7412G	Terminals 3 and 9	Terminals 22 and 28

9.1.3Missing Conditions

If a programmed POPIT is disconnected from the expansion loop, a missing condition appears immediately and the event is logged. The missing condition might also be sent to a central station or printed to an on-site printer, if programmed to do so. Refer to the D9412GV2/D7412GV2 Program Entry Guide (P/N: F01U003636) for programming options.

9.1.4Extra Point Events

Extra Point events are generated when a POPIT connected to the data expansion bus does not have an assigned Point Index. Table 12 shows when an Extra Point event is or is not generated. Table 13 on page 35 shows additional error conditions that can occur for the off-board points.
