Wiegand-style access control device (card reader) connected to the D9210B Access Control Interface Module

D9412GV2/D7412GV2 Operation and Installation Guide 3.0 Overview

The system can route groups of Event Reports to four different destinations. Each report group can be programmed to send reports to one or more destinations. Primary and backup reporting paths can be programmed for each destination and each report group. A custom option allows specification of individual Event Reports to be sent.

3.3.8Keypads

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 eight keypads. The control panel sends a Serial Device Trouble Report, SDI FAILURE in the Modem IIIa2 format or TROUBLE ZN D in the BFSK format, if it loses communication with a supervised keypad.

More than eight keypads can be added, but supervision of only eight is possible. Table 4 on page 13 shows the compatible keypads with the D9412GV2 and D7412GV2 Control Panels. Refer to Keypad in the D9412GV2/D7412GV2 Program Entry Guide

(P/N: F01U003639) for complete details on programming keypad options.

3.3.9Keyswitch

Maintained or momentary closure devices such as keyswitches allow any of the four available areas to be armed or disarmed. Point programming determines the loop responses and which area a keyswitch controls.

3.3.10 Access Control

The D9412GV2 can control eight access doors (each requiring the optional D9210B Wiegand Control Interface Module) with up to 996 uniquely identified cards or tokens. The D7412GV2 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

•Keypad

The access control features of the D9412GV2 and D7412GV2 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.

3.3.11 Event Memory

The system uses event memory to store events for each area. A D1255 Keypad or D1260 Keypad assigned to an area allows viewing of the events for the area. The control panel clears the events for an area from event memory and starts storing new events when the area is master armed.

3.3.12 Event Log

The system stores 500 to 1000 events and event modifiers from all areas in its event log. Event modifiers add information about an event to the log. Some events are always followed by a modifier. 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 and an event modifier showing the previous arming state.

All events and their modifiers 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 and event modifiers, refer to the appendix in the user’s guide for the keypad.

3.3.13 Ground Fault Detection

The Earth Ground Terminal on the control panels is electrically isolated from all other terminals to allow the D9412GV2 and the D7412GV2 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 16 for information on operating this function.

3.3.14 Ground Fault Detection Added Feature

When Ground Fault Detect is enabled (S4 closed), Points 1 to 8 can be used for non-powered fire- initiating devices such as heat detectors, four-wire smoke detectors, and pull stations. A D125B Powered Loop Interface or a D129 Dual Class A Interface Module is not required when connecting the non- powered fire-initiating devices to Points 1 to 8.
