Setting Up Panic
To fully enable Panic functionality for your CEM3, the following criteria must be met:
• a maintained contact closure has been wired to the panic circuit on the CEM3
backplane (for more information, see the Sensor3 CEM3 Data Terminations Guide
that ships with the Sensor3 rack),
• the “Emergency Contact” switch on the CEM3 backplane is the correct position for
the contact closure type (normally open “NO” or normally closed “NC”),
• a snapshot of the desired Panic look has been recorded in the CEM3 software.
To set the Emergency Contact switch on the CEM3 backplane:
Step 1: Remove the CEM3 control module.
Step 2: Move the switch labeled “EMERGENCY CONTACT” to the appropriate setting:
•
“NC” - Use this setting if the emergency contact closure is a “Normally
Closed” contact closure.
• “Disabled” - This setting disables the Panic function for this CEM3 control
module.
• “NO” - Use this setting if the emergency contact closure is a “Normally Open”
contact closure.
To record a Panic look:
Step 1: Set the desired output levels for any dimmers in your rack using any method
(methods include: Set Levels, DMX device, or sACN device).
Step 2: Using the CEM3 face panel, navigate to [Setup]>Panic>Record Panic
Look>[Enter]. If a panic look was already recorded, a confirmation screen will
appear asking you if you wish to overwrite the Panic look.
•
Select “Yes/Save” to overwrite the old Panic Look. The look will be saved.
• Select “No/Cancel” to abort the record. The look will be aborted.
Once a Panic look is recorded, when the emergency contact closure is triggered the Panic
look will be activated. When the contact closure is returned to its normal state, the Panic
look will be deactivated.
Other Panic Settings
From the Panic Setup menu ([Setup]>Panic) you have access to the following settings that
will affect the manner of a Panic look activation:
• In Delay (sec) - This setting determines the length of time (in seconds) for the Panic
look to delay before activating (default is 0).
N o t e : A Panic look can be recorded, regardless of if you have a wired Panic circuit.
W A R N I N G : Power must be turned OFF when you perform this procedure. Before
removing dimmer or control modules for service, de-energize main feed to
dimmer rack and follow appropriate Lockout/Tagout procedures as
described in NFPA Standard 70E. It is important to note that electrical
equipment such as dimmer racks can present an arc flash safety hazard if
improperly serviced. This is due to available large short circuit currents on
the feeders of the equipment. Any work on energized equipment must
comply with OSHA Electrical Safe Working Practices.
