32 CEM3 User Manual
Setting Up Panic
To fully enable panic functionality for your CEM3, the following criteria must be met:
• A maintained contact closure from a UL924-Listed triggering device 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, either 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:
1: Remove the CEM3 control module.
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:
1: Set the desired output levels for any dimmers in your rack using any method (methods include
[Test]>Set Local Levels and [Test]>Set System Levels on a CEM3 module, using a DMX device, or
using a sACN device).
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 new look will be saved.
• Select No/Cancel to cancel overwriting the old panic look.
After a panic look is recorded, the panic look will be activated when the emergency contact closure is
triggered. When the contact closure is returned to its normal state, the panic look will be deactivated.
Note:
A panic look can be recorded regardless of whether you have a wired panic circuit.
Note:
To configure panic mode through an electrical override without using the CEM3
module software, order the Hardwired Panic Accessory (7140K1002). Contact your
local dealer for more information.
WARNING:
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.
