DATA SHEET
UniBus 2 Door / 2 Reader Expander
The UniBus 2 Door / 2 Reader Expander can be used to provide control and
monitoring of two additional Doors or Readers on a compatible UniBus host
module. When connected to the Integriti Intelligent LAN Access Module, the
UniBus 2 Door / 2 Wiegand Reader expander can provide installation
configurations for 4, 6 or 8 doors. SIFER RS-485 readers can be assigned via the
Host Module for Read In & Read Out access control on each door. A maximum
of three UniBus 2 Door Expanders and a maximum of six UniBus boards in total
can be connected to the host module.
The UniBus 2 Door / 2 Reader Expander is designed for installation within the
same tamper protected enclosure as its UniBus host module. The UniBus device
is connected directly to the host module or another UniBus device via the
UniBus patch cable supplied.
Host Module Compatibility
The UniBus 2 Door Expander is compatible with the following
UniBus Host Modules:
• Integriti Intelligent LAN Access Module (Part. 996018) - Connect up to 3

Power Supply Input:
11V to 14VDC via host module
Current Consumption:
40mA idle
110mA both lock relays on
135mA both lock & DOTL relays on
NOTE: Current consumption does not include the current required by readers or other external devices such as locks, buzzers, lamps or
any device attached to the DOTL, Valid, Invalid, RS-485 Reader and UniBus connections
Over Current Protection:
Reader +V connections. Protected with self resetting PTC’s
Contact Ratings
UniBus Devices are designed for installation within the same
enclosure as the UniBus host module. A UniBus host can interface a
maximum of six UniBus devices in any combination, provided they
are all within the intended functionality of the host module
Lock Relays:
5 Amps @ 30VDC
DOTL Relays:
1 Amp @ 30VDC (Door Open Too Long output)
Connections
Lock 1 & 2:
Includes Lock+, Lock-, NO/COM/NC
Door 1 & 2:
Includes Reed, 2 x 0v, Tongue, REN, REX, DOTL contacts
Wiegand Reader 1 & 2:
Includes Valid, Invalid, 0V, Reader+, D1, D0, ARM
Lock Power:
Includes Lock+, Lock- connections from external PSU
UniBus Port: 3 x UniBus connections for loop-through and connection to host module
Power Considerations
The UniBus host module supplies static device current to all connected UniBus devices.
Total current consumption is therefore the sum of all:
- Static Current of all connected UniBus devices
- Static Current of host module
- Host module battery charging current
- Card Readers and Ancillary devices connected to DOTL,
Valid & Invalid connections
Lock Power Considerations
Lock power is supplied directly from an Integriti SMART PSU (Housed in the same
enclosure) and is the sum of the maximum current required by all connected
locking device hardware.
