FlexLock offers security for refrigerated medications or supplies. It can be attached to a
refrigerator storing thermal-sensitive medications or a supply cabinet. FlexLock is then
cabled to an Omnicell cabinet. The Color Touch screen can display the status of the
FlexLock (open/closed, locked/unlocked). A maximum of two FlexLocks can be attached to
one Omnicell cabinet due to power supply considerations. The FlexLock should be located
as close to the OmniSupplier as possible for best usage.
Other FlexLock features:
Up to 119 items can be assigned to each FlexLock.
An internal bin address is associated with each item. External bin numbers are not used.
An item cannot be assigned to the same FlexLock more than once.
An item cannot be assigned to more than one FlexLock.
An item cannot be assigned to a FlexLock and any other hardware locations at the same
time.
System Requirements
TempCheck
The TempCheck temperature sensor is an optional component of the Omnicell FlexLock
product. It can be included as part of a new FlexLock installation or retrofit to an existing
FlexLock.
TempCheck automates monitoring of the storage temperature for thermal-sensitive
medications. This product promotes increased patient safety, workflow efficiency, and
regulatory compliance.
Alerts warn the staff (pharmacy, RN, security) when the storage temperature is outside the
specified range for a better response time. Reports can be used to meet state and local
agency regulations. The Color Touch screen can display real-time storage temperature
readings through a diagnostics window.
A refrigerator or cabinet that fits the FlexLock template; extra
Color Touch Cabinets running Omnicell 7000 software or higher
Spacing: 12” length, 6” height, 6” depth (2” depth okay if refrigerator/cabinet can be slid
out to access the override lock)

Bin Addressing
FlexLock bin addresses are handled essentially the same way that the bin addresses in a
Sure-Med universal compartment are currently treated. The drawer type is FlexLock. The
location displayed is entered by the user at the OmniSupplier. If a user-entered description
is not provided, the field displays Flexlock #1, Flexlock #2, and so on. Like universal
compartment bins, FlexLocks do not support multiple bins, so items that are assigned to a
FlexLock cannot be assigned elsewhere, and vice versa. Only pharmacy items are
supported.
Items can be assigned to existing Remote Lock bins via the OmniCenter Database tab. The
Bin Assignment feature is accessed by selecting the Bins radio button on the Item Record.
Reports
The Pharmacy Drawer Configuration report and the Bin Assignment look-up list are used to
support FlexLock.

The FlexLock can be connected to a cabinet or a workstation. It can also be daisy-chained to
an External Return Bin (ERB) or another FlexLock.
The cabinet or workstation acts as a host providing power to the FlexLock directly or
indirectly through a daisy-chained ERB or another FlexLock.
The host cabinet or workstation must be powered down to work on the FlexLock as it does
not have its own power switch. This is true even if the FlexLock to be serviced is in a daisychain and not directly connected to the host cabinet or workstation.
Some services require the disconnection of the FlexLock cables for replacement or to allow
the host equipment to be used while service is being completed on the FlexLock.
