116 bright blue Installation Manual
In a multiplex configuration, each VRI-1 board is connected to any one of the Device connectors (Device 1-1
through 2-16) on the
bright blue
controller with TB1 for RS-485 communications and TB2 for power on a VRI-1 in
parallel. A maximum of 16 VRI-1 boards can be connected to each channel in this manner.
Note:
Only identical protocol devices can be connected on the same channel on the
bright blue
. VRI-1 devices
cannot be wired on the same data channel with any older Vanderbilt or Schlage devices.
Daisy chain configuration
In a daisy chain configuration, the VRI-1 reader interfaces are connected to one another in series. A maximum of
16 devices can be connected to a
bright blue
data channel. This configuration is not recommended by
Vanderbilt; if a wire is broken in the loop, downstream devices will not communicate with
bright blue
.
PIN Functions
TB2
– Power source and contact inputs
Provides power to the VRI-1 from the
bright blue
. 12
– 24 VDC 10% filtered power required. Two supervised or
unsupervised contact inputs are provided, typically for DOD and REX monitoring. Contact inputs have individual
grounds. Supervised door contacts support a maximum wire length of 1,000 ft. Unsupervised door contacts
support a wire length of 2,000 ft.
▪
PIN 1 is Power (VIN)
▪
PIN 2 is Ground (GND)
▪
PIN 3 is Door Contact 2 (Normally Closed)
▪
PIN 4 is Door Contact 2 (Normally Closed)
▪
PIN 5 is Door Contact 1 (Normally Closed)
▪
PIN 6 is Door Contact 1 (Normally Closed)
J2
– Reader Interface Addressing
The address of the VR-1 is dependent on the position of jumpers on these pins. Please see the section on
Addressing VRI-1 for more details.
J3
– On Board Tamper Connection
The enclosure tamper switch will be wired to the supplied tamper connector flying leads. Polarity is not a concern.
J4
– RS485 Communication Line Terminator
