Determining which Lock Pawl to use
A
• As all cabinets vary, we offer a wide range to pawls to suit the particular dimensions of your cabinet.
• There are 2 simple measurements that need to be taken to determine which pawl you will need.
• Please obtain the measurements as show in Figure 1 and Figure 2 and contact our electromechanical lock support
team as show below:

Mounting the Control Unit
• Mount the db ServerRack v2 Zero-U Control Unit
o The Control Unit can be attached using the Magnetic Strips for Steel Cabinets or VHB Strips for Aluminum
Cabinets.
o Alternatively, the Control Unit can be placed on a cabinet shelf
• It is preferable to mount the Control Unit near the top of the rack, to ease the running of cables, however this isn't
absolutely necessary.

Mounting the Door Interface Box
• If you are installing the db ServerRack Access Control unit to a cabinet that already has a lock installed, remove the
existing lock at this time.
• The "Door Interface Box" provides an interface between the Control Unit and the fingerprint scanner. It also provides
all power and signal connections to the electric lock.
• Install the Door Interface Box as show in Figures 4 thru 9.
Mounting the Door Interface Box - Step 1
• Before removing the double-sided high bond tape from the Door Interface Box, find a suitable location on the inside
of the cabinet door to mount Interface Box.
• Ensure that the selected location will not affect the cabinet door from closing correctly.
• Note that for glass paneled cabinet doors with very narrow frames, the only suitable location may be on the glass.
IMPORTANT:
• Ensure that the Interface Box is located close enough to the lock opening in the door, so that the finger-
sensor on the ribbon cable can go through the door and connect into the lock, see Figure 6.
• Once you have found a suitable location where you intend to mount the Door Interface Box, ensure that the door
surface is clean and free from any debris. (Using neat alcohol to clean the surface is highly recommended. Allow
drying time before proceeding.)
• Remove the protective cover from the double-sided high bond tape located along the edge of the Door Interface
Box.

Mounting the Door Interface Box – Step 2
• Attach the Door Interface Box to the inside door surface. Only apply a slight amount of pressure to the high bond
tape until you have ensured that the Door Interface Box will not prevent the cabinet door from closing.
• Once you have ensured that the door will close properly and the finger sensor can attach to the lock, apply more
pressure to the high bond tape. The more pressure applied, the greater the bond.
Figure 5
IMPORTANT:
Ensure that the Interface Box is located
close enough tothe lock openingin the
door, so that the finger-sensor on the
ribbon cable can go through the door
andconnectintothelock,seeFigure6.

Mounting the Door Interface Box - Step 5
• Secure the lock to the door using the Top Mounting Bracket and Bottom Mounting Bracket as show in Figure 9. Do
not over-tighten the screws in the Bottom Mounting Bracket as this may jam the lock mechanism.
• Attach the lock wire coming out of the Door Interface Box to the back of the lock as shown in Figure 8. The wire will
only plug in one way.

Using the Alarm Output
• Certain events create an alarm condition. These events are:
~ A door/panel with a Tamper Switch Attached was opened.
~ A door/panel with a Door Contact Switch was opened without a valid fingerprint identification.
~ A door/panel with a Door Contact Switch was opened and left open for longer than the Propped Door
Delay (set via the DAS software).
~ A Duress Finger was used to open a cabinet. This will be a silent alarm at the cabinet, but will still trigger the
Alarm Output.
• The Alarm Output provides a method to connect the db ServerRack Access Control unit to a third-party product, to
alert it that an alarm condition has occurred.
• The Alarm Output terminals are shown in Figures 19a and 19b.
