9.1.5D9412GV2/D7412GV2 Responses to Missing Point Conditions

The D9412GV2 and D7412GV2 respond to missing point conditions based on the point’s programming and the armed state of the point’s area. For example, if an interior motion detector point is missing during a disarmed state, a Missing Trouble event is generated; however, if the point is missing while the area is Master Armed, a Missing Alarm event is generated. Non-fire, 24-hour points always generate a Missing Alarm event whereas Fire points always generate a Missing Fire Trouble event.

9.2D8125, D8127 and D9127 POPIT Modules

D8127 and D9127 POPITs use the D8125 POPEX Module to report to the control panel. Each D8125 supports up to 119 POPIT points. Connect two D8125 Modules to the D9412GV2 to bring the combined total number of POPIT and on-board points to 246. Points 9 to 127 connect to the first POPEX Module. Points 129 to 247 connect to the second POPEX Module. The D9412GV2 reserves Points 128 and 248 for internal use. The control panel annunciates activity only for each POPIT, not for each detection device connected to the sensor loop.

There are two versions of the D8127 and D9127 Modules. Both module enclosures are made of UL Listed fire resistant material. D8127T and D9127T Modules contain tamper switches. D8127U and D9127U Modules include untampered covers. Unless the module is mounted in a tampered enclosure, UL requires D8127T and D9127T Modules for certificated accounts.

Listings

The D8125 POPEX and the D8127 and D9127 POPIT Modules are UL Listed for Local or Police Connected Burglar Alarm, Central Station Burglar Alarm, Household Burglar Alarm, Central Station Fire, Local Fire, Remote Station Fire, Household Fire, and Electrically Actuated Transmitter Applications.

Refer to the D9412GV2/D7412GV2 Approved Applications Compliance Guide (P/N: F01U003639) to determine the required equipment and enclosures for the application.
