3.3.7 Keypads 
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 IIIa
2
 
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.

3.3.8 Keyswitch 
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. 
3.3.9 Access 
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: 
  Wiegand-style access control device (card 
reader) connected to the D9210B Access Control 
Interface Module 
  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.
