3.3.7Keypads
Up to 32 unsupervised keypads can be connected to the system. The available power, number of supervised keypads, and number of areas covered affect the total number of keypads that can be connected.
The system can supervise up to sixteen D1255 keypads (all models), and up to eight D1260 keypads (all models). The control panel sends a Serial Device Trouble Report, SDI FAILURE in the Modem IIIa2 format or Expansion Module Failure (333) in Contact ID format, if it loses communication with a supervised keypad.
More than 16 keypads can be added, but the system can only supervise up to 16 keypads. Table 4 on page 13 shows the keypads that are compatible with the D9412GV3 and D7412GV3 Control Panels. Refer to Keypad in the D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) for complete details on programming keypad options.
UL requires all Fire System keypads to be supervised.

3.3.8Keyswitch
Maintained or momentary closure devices such as keyswitches allow any of the available areas to be armed or disarmed. Point programming determines the loop responses and which area a keyswitch controls.
3.3.9Access Control
The D9412GV3 can control eight access doors (each requiring the optional D9210B Wiegand Control Interface Module) with up to 996 uniquely identified cards or tokens. The D7412GV3 can control two access doors with up to 396 uniquely identified cards or tokens. Any of the following can grant access:
∙
∙Request to enter (RTE) or request to exit (REX) input
∙Unlock command on a keypad
The access control features of the D9412GV3 and D7412GV3 can deny access during armed periods. The control panel can also grant access only to certain authorized users depending on whether the area is master armed, perimeter armed, or disarmed. Programming for automatic disarming when designated authorized users are granted access is also possible.
3.3.10 Event Memory
The control panel retains point alarm and trouble events in memory for each area. A D1255 (any model) or a D1260 (any model) can be used to view event memory by using COMMAND 40. The control panel clears the previous events for an area from the event memory when the area is armed.
3.3.11 Event Log
The system stores 800 events from all areas in its event log. For example, the system adds at least two items to the log each time an area is armed or disarmed, the open (or close) event that also contains the previous arming state.
All events can be stored even if the control panel does not send a report for them. The log can be viewed at a keypad, printed locally using the D9131A Parallel Printer Interface Module and a parallel printer, or uploaded using Remote Programming Software (RPS).
For a list of the log events, refer to the appendix in the user’s guide for the keypad.
3.3.12 Ground Fault Detection
The Earth Ground Terminal on the control panels is electrically isolated from all other terminals to allow the D9412GV3 and the D7412GV3 to detect ground fault conditions. A Ground Fault Detect Enable switch (S4) is located just under Terminal 10, Earth Ground, on the control panel. Refer to Section 4.5.2 Ground Fault Detect Enable on page 15 for information on operating this function.
