Overview
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).
Features
UL 924 Listed Accessory
Detects loss of normal power and automatically sends signal to
lighting control panel
Allows Greengate panels to be listed as UL 924 when RRU-1 is
connected

UL 924 Listed
The RRU-1 provides a dry contact closure to the ControlKeeper M
and MB panels when normal (grid) power is lost. This contact
closure forces a hardware override of all relays in the enclosure to
the ON state. This override condition takes priority over any relay
commands from the system controller and will remain in effect until
the contact closure from the RRU-1 is opened.
Installation
The RRU-1 can be installed next to the lighting control panel
enclosure.

To override On:
Connect dry contact between the On
terminal and the +24 VDC terminal.
When contact closes, all relays are
forced ON. Contacts within the RRU-1
will automatically close when normal
power is lost
