9.1.1POPIT Modules

The D9412GV3 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 D9412GV3 can monitor to 246. The D7412GV3 provides up to 67 off-board points, bringing the total number of points the D7412GV3 monitors to 75. Each off-board point requires a POPIT Module.

The expansion bus can be shared between fire and non-fire devices where the POPIT module provides data isolation between the input and the bus connections.

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 10).

Model	Power		Data

			or
			Terminals 27 and 28
D7412G		Terminals 23 and 24	Terminals 27 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 D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) 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 11 shows when an Extra Point event is or is not generated. Table 12 on page 37 shows additional error conditions that can occur for the off-board points.
