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
powered by the
Extender (the output
is a relay).
Use standard wiring and
Phoenix connectors.
