7. MAINTENANCE AND CLEANING

The V-Station 4G and V-Flex 4G devices require very little in the way of daily maintenance except for

occasional cleaning and disinfecting. The V-Station 4G and V-Flex 4G devices feature field-replaceable

sensors.

V-Station 4G and V-Flex 4G fingerprint sensors can be replaced quickly and easily in the field.

The following sections explain in detail the steps required to replace a sensor.

ISARMING THE TAMPER PROTECTION

The Tamper Switch is a momentary push-button switch on the back of the device within

the I/O cable interface pocket (see Figure 7-1).

The tamper protection feature allows the device to sound an audio alert, flash LEDs,

send a pre-defined Wiegand string to the control panel, or disable biometrics if the tam-

per switch is triggered.

With the wall mounting plate mounted and the device secured to the mounting plate, the

tamper switch is depressed, closing the electrical circuit. When the device is removed

from the wall by removing the security screws or in the event that the device is removed

from the wall by force, the tamper switch opens.

To access the tamper-protection setting on the V-Station 4G device using the keypad:

1. Enter the Admin menu on the device by pressing the Left arrow and Enter keys

simultaneously.

2. Key in the Admin password (default is "0000") and press OK.
