RideThru Option Kit
Install the RideThru Option Kit
The RideThru Option kit provides power for the Architectural Control Processor for a
minimum of 12 seconds during brief power outages or power drop outs. The RideThru
Option board fully charges and is ready for operation within ten minutes of the DRd being
powered.
Step 1: Align the RideThru Option board to the mounting studs in the bottom of the
enclosure.
•
Notice the mounting holes on the option board. Two are open ended slots
used to place the board, and the remaining two standard mounting holes
used to secure the board in place.
• Align the open ended slots to the studs and rest the other end of the board
on the mounting studs.
Step 2: Secure the board to the two mounting studs with the screws provided.
N o t e : A single DRd supports the use of either the Unison RideThru Option or the Unison
BatteryPack Option, but not both in the same enclosure.
W A R N I N G : Risk of Electric Shock! The Unison RideThru option board retains an
electrical charge even when power to the DRd is off.
