Using the Door Contact Inputs
•
The db ServerRack Access Control unit provides Door Contact Inputs for both Door 1 and Door 2. The Door Contacts
should be located on the respective door containing the BioLock attached to either the Door 1 or Door 2 connector.
•
Use the supplied Door Contact.
DO NOT USE ORDINARY REED SWITCHES AS THESE WILL CAUSE THE PRODUCT TO GO INTO A CONTINUOUS
ALARM CONDITION.
•
Pins 9 thru 12 are used for the Door Contacts, as show in Figures 17a and 17b.
Figure 17a
Figure 17b
•
Door Contacts are connected to either of the following pair of connector pins, 9 & 10 or 11 & 12.
•
If any of the Door Contacts are not being used, that pair of connectors must be connected with one of the supplied
terminating resistors. Please wire resistors as show in figure 17c so as to avoid any or the resistor leads touching.
IF ANY RESISTOR LEADS TOUCH, THIS WILL CREATE AN ALARM CONDITION.

To use one of the Door Contacts follow the example show in Figure 18. The example connects to pins 9 & 10, an
additional Door Contact can be connected to pins 11 & 12.
