Rack Options
Unison ERn options include the RideThru Option (URTO) kit, BatteryPack Option kit
(UBPO), Ethernet Switch Module (ERn-NET), and the Redundant Rack Power Supply
(ERn-RPS).
Additionally you may use a Station Repeater Module in the ERn4 enclosure top module slot
instead of a secondary Paradigm Station Power Module. See “Install a Paradigm Repeater
or Dual Repeater Module” on page 31.
Install the RideThru Option (URTO) Kit
The RideThru Option kit (URTO) provides power to the Paradigm Architectural Control
Processor for a minimum of 12 seconds during brief power outages or power drop outs. The
Ride Through option board fully charges and is ready for operation within ten minutes of the
ERn enclosure being powered.
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 ERn enclosure is off.
N o t e : A single ERn enclosure supports the use of either the Unison RideThru Option
(URTO) or the Unison BatteryPack Option (UBPO), but not both in the same
enclosure.
N o t e : One Unison RideThru Option board powers one Paradigm ACP. therefore an
ERn4 enclosure with two Paradigm ACPs installed requires two RideThru Option
boards.
