Hardware Options

The available hardware options vary depending on

the type of panel selected. The AEP-5 (supervised

input board) and ERB (Expanded Relay Board) are

only used with PW-2000-II panels.

If the Groups option is selected, you can select one

or two AEP-3 Output Expansion Boards. Each

board adds eight output relays to a panel.

Host Grant

Host Grant options provide fault tolerance should a

card not be found in the panel. Host Grant options

are used when, for example, the total number of

cards that are to be valid at a panel exceeds the panel

capacity or if the card update scheduler is used and

the card is presented before the scheduled update

has occurred.

There are three modes of operation of Host Grant.

Disabled: The card number must exist at the panel

for access to be granted. The Host (WIN-PAK 2.0)

computer will not grant any access.

Open Door: If a card is received as an alarm event

from the N-1000, with Host Grant set to the

OpenDoor mode, the event will be checked against

the WIN-PAK 2.0 database. If the card is valid for

access at that door and time, then a pulse (door

open) command is sent and the event is treated as a

normal card event in history. The Event View will

show it as "Host Grant – Door unlocked" along with

card-holder name and other related event

information. If the event oocurs outside the two

minute time limit, it is processed as an alarm event

and access is not granted.
