Overview
The Lighting Relay Module (LRM) is available in 347 VAC input
voltage. The LRM is designed to force all relays in a lighting control
panel to an ON or Closed state, regardless of the control panel
programmed relay status. This allows the closure of relays 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.
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 LRM is
connected

Description/Operation
The LRM 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 LRM is removed.
Installation
The LRM 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.
