Overview
The Lighting Relay Module (LRM) is available in 347 VAC input
voltage. The LRM is designed to force all outputs in the lighting
control panel to an emergency scene regardless of the control panel
programmed output status. This allows the override of outputs
during loss of normal (grid) power to allow an alternate power source
to drive the lighting loads. Once the LRM senses the normal power
returning, the control panel will return to the normal programmed
operating mode.

Operation
The Lighting Relay Module provides a dry contact closure to the
Source Controller panel when normal (grid) power is lost. This
contact closure performs an override of all outputs in the enclosure
to an emergency scene. This override condition takes priority over
any output commands from the system controller and will remain in
effect until the contact closure from the LRM is removed.
Installation
The Lighting Relay Module can be installed next to the Source
Controller.

For Emergency panel configurations, ensure
the Source Controller is fed from an emergency
power source.
The LRM needs to provide a dry contact
maintained closure to the Switch Input 1 or
Switch Input 2 terminal on the Source Controller
input card.
Emergency actions can be programmed from
the Source Controller on board user interface.
