Options
All AirCleaner
®
models support the Redundant Power, Panic Button Control Panel, and Panel Button Y
Cable options.
Redundant Power Supply
This option provides an additional power supply to guard against complete system failure in the event
of a single power supply failure. Both power supplies operation in a load sharing configuration but
AirCleaner
®
will run on a single power supply. In the event that one of the power supplies fails, the
remaining operational power supply will automatically take over the complete power load.
Panic Button Control Panel
The Panic Button Control Panel provides a simple two-button interface (one button for Video, the other
for Audio) that sits on a desktop and is connected to the AirCleaner
®
chassis via a DB9 cable.
Tip:
A Soft Panic Button Panel is available in DashBoard for Operator 1.
The Panic Button Control Panel is used to trigger the video and/or audio mask in the event of a visual
or aural offense. Pressing the specific button (
AUDIO
or
VIDEO
) will tell AirCleaner
®
to mask the content
according to how the AirCleaner
®
is programmed. The masking will continue for the duration the button
is held down.
The Panic Button Control Panel communicates to the AirCleaner
®
chassis over a standard GPI connection.
The Panic Button Control Panel ships with a 33-foot shielded cable for connection to the GPI connector
on the AirCleaner
®
chassis.
