Using the Sensor Inputs

When the Control Panel sends out a macro to switch multiple A/V components on or off, discrete

codes are normally used to ensure the state of the component. In some cases, only toggle codes are

available: one command toggles between the on and off state, and there is no separate command

for switching the component on and switching it off. In this event, the system may get out of sync.

This problem can be solved by using power sensing:

• A power sensor connected to an A/V component can detect whether it is switched on or off.

By connecting the power sensor to the Extender, this information is subsequently transmitted to

the Extender.

• Some A/V components, such as receivers, have mini-jack outputs specifically for this purpose.

These mini-jack outputs can be connected to the power sense inputs on the Extender.

• For video sources, video sensor modules can be used.

Make sure that you create the specific power sensing commands in the action list of

Wizz.it Ex.

Note Sensor modules are not delivered with the Extender, but most available modules are

compatible with the Extender. The power sense inputs are triggered by a voltage input

between 5V and 30V.

Use this wiring

solution if the

sensor module’s

output provides a

voltage level.

Use this wiring

solution if the

sensor module is

Extender (the output

is a relay).

Use standard wiring and

Phoenix connectors.
