VO-4e REAR PANEL

Connections

All numbered audio, relay and power connectors on the rear panel of the unit are congured with the lowest output or input on the left of

the connector as viewed from the rear of the unit.

Auxiliary Power

Dual 24V DC power inputs are provided on a four-way 0.2” (5.08mm) pluggable screw terminal

block. Monitoring of the supply input is software congurable. If 24V DC is not supplied to a

monitored input, a loss-of-supply fault will be reported. If no Auxiliary Power monitoring is required

the option must be deselected in the Vocia software to prevent an Auxiliary Supply Fault being

reported. A Loss of Supply Fault is indicated via the Vocia software and by a blinking yellow

‘Chassis Fault’ indicator on the front panel. Auxiliary power supplies must meet the voltage range and power requirements detailed in the

following specication table. Local standards, norms or codes may require the use of certied power supplies and may require observance

of minimum ‘on battery’ running times both for standby and maximum power conditions. If used, dual 24V redundant power supplies must

each independently meet the total power requirements of the unit.

The pluggable screw terminal connectors provided will accommodate wire sizes from 12-18 AWG. External over-current protection must be

provided, according to the current carrying capacity of the connecting wires. The Auxiliary power inputs must not be connected to Chassis

or ground. The Auxiliary power must be oating with respect to ground.

Network Connections

The VO-4e is a CobraNet device. A Primary and Secondary CobraNet connection is provided for

this. These connections support powering via 802.3af or 802.3at (type 1) PoE switches or external

PoE Supplies. Monitoring of the PoE supply input is software congurable. If PoE power is not

supplied to a monitored input, a loss-of-supply fault will be reported. If no PoE Power monitoring is

required the option must be deselected in the Vocia software to prevent a PoE Supply Fault error

being reported. A Loss of Supply Fault is indicated via the Vocia software and by a ashing yellow

‘Chassis Fault’ indicator on the front panel. All CobraNet routing and bundle assignments are processed by the Vocia devices locally.

Vocia makes dynamic use of available bundles in CobraNet. A 100Base-T Ethernet switch (not repeater hub) is required when networking

multiple units. CobraNet utilizes standard CAT5, CAT5e, CAT6, or CAT7 cabling, which has a specied maximum length of 328 feet (100

meters). Additional Ethernet switches, or switches which provide ber-optic interface, can be used to extend the physical distance between

units within a network. Please note that CobraNet limits network extensions to seven hops (one-way transmissions) within a network. The

CobraNet network connection is congured with the Primary connector on the left and the Secondary (redundant) connector on the right.

The Primary and Secondary CobraNet ports are provided to facilitate connection redundancy. Each connector provides two LEDs that

indicate Ethernet link and network activity.

Caution - Due to potential energy hazard, connections to the Auxiliary Power 24V DC

inputs must be made by a qualied electrician or other qualied person as

required to conform with all local codes.
