Overview
The The Remote Relay Unit (RRU-1) is available in 120 VAC and 277
VAC input voltage configurations. The RRU-1 is designed to force
all outputs in the lighting control panel to an emergency scene
regardless of the control panel’s 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 RRU-1 senses the normal power returning, the control panel will
return to the normal programmed operating mode).

For Emergency panel configurations, ensure
the Source Controller is fed from an emergency
power source.
The RRU-1 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.

Operation
iCAN
The RRU-1 provides a Normally Closed (N/C) 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 RRU-1 is opened.

Connect dry contact from RRU-1 to Switch Input 1 or
Switch Input 2.
Installation
The RRU-1 can be installed next to the Source Controller.

When contact closes all relays/dimmers are forced
to an emergency scene. Contact of the RRU-1 will close
when normal power is lost.
