MAX SETTING OPTIONS

Setting with User Cards/Tags/Fobs

MAX user cards/tags/fobs can be used to set the system. This is done by assigning a MAX user card (tag or fob) with one of the setting options. When the MAX card is held against a MAX module for five seconds, the MAX function is activated. For example, if the MAX function assigned is 13 = Part Set, then activating the card held function results in the system being part set.

If a user is assigned group choice, then a keypad will have to be accessed to select the group for setting after swiping the card.

Dual Focus

If a # is assigned to a particular users pin and their max card number, then the user will have dual focus operation. This means that they will have to enter their pin first, before setting with the max card and vice versa.

Keyprox

A keyprox is a keypad that has a card reader built in. They are normally installed on systems where dual focus setting and unsetting are used. Keyproxes are used as a keypad and MAX as detailed above, but the card is held against the lower right corner of the keypad as shown in the following diagram:
