Analog Audio Outputs
Four 0.2” (5.08mm) three way pluggable barrier strip connectors are provided for analogue audio signal
output. The Vocia software enables a nominal output level of -10dBu, 0dBu or +4dBu to support a wide
range of connection devices.
Page Active Relays
Page Active Relays (PAR) are provided in the form of one Form C (single pole, changeover) relay
presented per output channel. Each PAR connector is a six way 3.5mm pluggable barrier strip connector.
The Page Active relay connections are labeled as follows: • C – Relay Common • NC – Normally Closed •
NO
– Normally Open
Control Inputs
Four separate Control Inputs are provided via a six-
way 0.2” (5.08mm) pluggable screw terminal block.
Each Control Input allows for an external voltage-free contact closure to ground to assert a Control Input
Event as configured in Vocia software. In addition to the four control inputs, a ground and 10V reference
Out (100mA) is provided. When configured for device failover the Control Input connections must be
paralleled between the main and failover device.
Control Outputs
Four Control Outputs are provided via two six-
way 0.2” (5.08mm) pluggable screw terminal blocks. Each
Output has a Common, Normally Closed (NC) and a Normally Open (NO) connection. Outputs will be
capable of being associated with control Output Events configured in Vocia software. Both NC and NO
connections are able to be used at the same time. When configured in a Failover Mode the Controls
outputs are able to be used to indicate the active state of the respective output channel. When configured
for device failover as NO and NC relay connections are being used, consideration should be given to the
performance of the circuit before and after failover.
