STEP 7
Emergency Power Mode
Perform this step only if you want to configure an emergency power mode when normal power is lost. All
control station inputs and time clock events are ignored while in emergency power mode. This step defines if
the panel has emergency circuits and, if so, how to configure the emergency settings. For multi-panel systems,
emergency settings are configured on the master panel and each remote panel.
•
Identify panels fed by normal (non-essential) power. Move their
emergency switches
to the left position, see
illustration below.
•
For all the emergency (essential) lighting panels, move the
emergency switches
to the right position, see
illustration below.
•
The essential and non-essential panels must be connected by a sense line wired to
terminal 5
on the link
connector on the
LCP128
controller, see illustration below. (For wiring details see the
LCP128 Installation Guide
).
In this configuration, the emergency (essential) lighting panel will “sense” the normal panels’ power. When
normal power is lost, the emergency panel will go to the emergency settings (factory set to all circuits On).
Notes:
•
If UL 924 certification is required, the Lutron Emergency Lighting Interface (LUT-ELI-3PH) may be used to
meet code. The LUT-ELI-3PH senses the normal (non-essential) line voltage on all three phases (3PH) of
normal power. When one or more phases of power are lost, the LUT-ELI-3PH will send a signal to
terminal 5
on the LCP128 controller(s). When the
emergency switch
is set to the right position
(essential), the emergency lighting settings will be recalled. The LUT-ELI-3PH can be used with one or
multiple panel systems.
•
Loss of normal power can be simulated by turning off all connected normal (non-essential) panels’ control
breaker.
•
When the emergency switch is in its center position (as shipped), terminal 5 on the panel does not
respond to the emergency.
