Hosts the Redwood Open
Application Framework, which
provides two-way communication
and systems integration between the
data collected by the Redwood
Platform and other external
applications or systems.
Manages policies, communicates to
Redwood Gateways, distributes lowvoltage DC power to all fixtures, and
collects sensor data.
Profiles fixtures, aggregates sensor
data, sends sensor data to the
engine, and manages power
connections between engines and
fixtures.
Turns on and off any light fixture type
(e.g. fluorescent, CFL, HID, LED,
etc.) and provides output signals to
control one or two external dry
contact relays.
Designed for applications that require
a load to be switched on during a
loss of normal power or an engine
failure, the relay can activate a
system in the specific area(s) served
by the Engine.

Extends a standard fixture whip

(60cm) from the fixture.
Light source
The Redwood Engines can communicate to loads, fixtures and Sensors via the following mechanisms.
1. The Redwood LED and Universal Gateway is a two component, structured cabling-friendly
option that works with the Redwood Sensor. This option was designed for greater flexibility
during installation: there are connector options for category or 18AWG cabling, which connect to
a separate sensor for installation in different spaces.
2. The Redwood Universal Gateway – Outage Relay is used in conjunction with a dry contact
relay to communicate the system health of a Redwood Engine. Designed for applications that
require a load to be switched on during a loss of normal power or an engine failure, the relay can
activate a system in the specific area(s) served by the Engine.
3. The Redwood Adapter, which integrates the sensor and gateway into one component. Ideal
when a separate gateway and sensor are not required.
These are described in this document.

2 Power Requirements and Recommendations
2.1 Low-Voltage Cabling Requirements
An LED Gateway or Adapter connected to a fixture requires 1, 2, or 3 ports from the Engine to power the
fixture, depending on the power requirement specifications of the fixture. A port can be connected with
either standard category cabling, or with 18 AWG low-voltage wiring, comprised of stranded or solid
wire.
In the case of category cable, all four twisted pairs will be used to form one port connection to the
engine.
For 18 AWG wiring, the cable may be shielded or unshielded. For both cases, the wiring or cable must
be UL listed, such as types CL2 or CM, and suitably rated for its intended installation environment (e.g. –
P if the cabling is routed through plenums).
To minimize voltage loss in the cable, the following maximum run-lengths should be observed:
Low-voltage wire type Max Length (ft) Max Length (m)
Category Cable (5e, 6/6a) 328* 100*
18 AWG 328 100
* The 328ft/100M length can only be achieved when all four twisted pairs will be used to form one port
connection to the engine; otherwise the length is limited to 75ft/23 meters.
2.2 Redwood Engine Power Requirements
The Redwood Engine is available in two versions: a 277V AC power input version and a 120V - 250V
AC power input version.
A dedicated branch circuit for each Engine is recommended. However, you can have two 277V engines
on a single 20Amp circuit provided these are the only equipment on the circuit. This will ensure that no
other loads on the same circuit draw too much current from the branch circuit and thereby not allow the
Engine or Engines to operate continuously.
