IMPORTANT: Safety Advisories
All installation and rigging work done must where applicable be designed and built in
accordance with norms and standards of the local authority having jurisdiction of the
installation site. It is the responsibility of the installer to obtain such approvals as may be
required to achieve full compliance.
All electrical work must be carried out by a suitably licensed electrical contractor in full
compliance with local electrical standards.
Lifting: some enclosures and the equipment inside them may be heavy. Use properly rated
lifting equipment where appropriate and never attempt to carry out work with fewer than
the number of workers needed to lift safely.
It is the responsibility of the installer to ensure that all local building, safety and electrical
codes are strictly adhered to in the installation of this enclosure. Tempest Lighting, Inc., its
employees and agents are in no way responsible for damage arising from failure to follow
either the instructions in this manual or building, safety and electrical codes prevailing at
the installation location.
Do not attempt to install or operate the enclosure before fully reading and understanding
this manual
Never allow anyone who has not read this manual to open the enclosure or perform
maintenance on the luminaire within.
Never leave the enclosure unattended when open.
Always make sure all bolts and latches are tight and safety locks are in place after
performing any form of maintenance on the unit.
Do not open any electrical boxes until power has been shut off to all supply lines to the
enclosure (including the one powering the luminaire).
Do not open the enclosure in wet weather.

Tempest enclosures may be wired on single or double
circuit supplies. On a single feed, both enclosure and
luminaire are permanently on. With a split (double) feed
supply, you can switch off the luminaire when not in use,
while the enclosure continues to protect it 24/7.
Tip: most people use single feed.
Tip: even wired for single feed, you can use DMX to switch
the luminaire power on and off – see the DEC4 section
below.
Single Feed
Enclosure and luminaire are permanently on.
Enclosure and Luminaire must be rated for the
same voltage.
Supply must be rated for luminaire current plus
150 watts.

Remote Monitoring Connections
Tempest G4 enclosures optionally support four types of
remote monitoring:
1. Direct via Ethernet, using Tempest TEMP
protocol (see Appendix – TEMP Protocol)
Requires 51.EN Ethernet board
2. Grouped via RS485, using an Ethernet bridge and
Tempest TEMP protocol (see Appendix – TEMP
Protocol)
Requires one 51.485 RS485 board per enclosure
and one 51.EN Ethernet board per bridge
3. Grouped via RS485, using DMX/RDM – see next
page
Requires one 51.485 RS485 board per enclosure,
and one JESE RDM-TRI Interface

DMX/RDM Monitoring Network
Note: Tempest System Manager and web-based monitoring will be available early 2017
The 2000.195 JESE RDM-TRI MK2 passes
DMX information from a show control
system to each DEC4 controller.
Set a DMX address for each controller in the
range 1-510. See DEC4 section below for
more information.
Page 23
Tornado G4 User Manual 23
RS485 (DMX/RDM) Cable Terminations
Loop a shielded twisted pair cable (eg Belden 9841, though
many people now use a CAT5e cable) from the
control/monitoring point, around all enclosures.
Maximum total cable length is 1,200M (4,000ft). For longer
runs and wildly distributed systems, use a DMX/RDM
splitter (make sure that it supports RDM) and multiple
cable runs.
Use the termination switch to terminate each RS485 cable
run at the last enclosure on each run.
Luminaire Power Control using DMX512
The DEC4 controller includes a 30A 2-pole relay that
protects the enclosed equipment in the event of a serious
high temperature event by cutting off power.
You may use DMX512 to control power to the luminaire
inside the enclosure. This is very useful in hot locations,
where the luminaire may be stressed by being held in
standby mode all day under hot sun. By powering the
luminaire down it will tolerate much higher temperatures
without harm.
Tempest recommends the JESE RDM-TRI interface to
monitor enclosure status in any installation and control the
enclosure power relay in smaller systems.
More complex installations are very likely to include some
kind of show control system that will certainly include DMX
control. This is the preferred method of controlling power
to the luminaires.
JESE RDM-TRI interface connects to
a PC via USB to monitor and control
a network of Tempest enclosures.

Digital Enclosure Control
DEC4TM – that’s Digital Enclosure Control, fourth
Generation – is the brain of your Tempest enclosure. It will
maintain the internal environment in a comfortable
temperature and humidity range, and prevent
condensation – the real killer of outdoor equipment. DEC4
monitors internal and external temperature, humidity and
lamp current at all times, and uses this information to
control the enclosure’s lamp relay, fan(s) and heater(s). It
can report back over an RS485 network, using the RDM
protocol (Remote Device Management), or connect to
your TCP/IP network for remote monitoring and
management using Tempest’s TEMP protocol.

DEC4 Main Functions
1. Sense current to luminaire (lamp on/off)
2. Record lamp hours
3. Monitor temperature and humidity inside
Enclosure
4. Monitor temperature outside enclosure
5. Maintain internal temperature at safe operating
level
6. Maintain relative humidity within safe limits to
prevent condensation
7. Isolate luminaire in case of unsafe temperature
8. Report status over RS485, RDM, TCP/IP
9. Maintain positive pressure (optional) 24/7 to
prevent ingress of salt air and other
contaminants
10. Circulates air internally to prevent hot and cold
spots when luminaire is idle
DEC3.3 constantly monitors the following parameters:
Luminaire/Luminaire current
Line Voltage
Temperature
Humidity
DEC 3.3’s patented GoldilocksTM algorithm uses a combination
of sensors, heaters and fans to maintain a safe operating
temperature and a safe relative humidity level that will not
allow condensation to take place.
As air is heated it is able to support more moisture without
condensing, so Goldilocks uses heat to raise the air temperature
inside the enclosure in the event that relative humidity
approaches dewpoint.
Factory Settings – Basic Mode
In most applications, DEC3.3 will operate correctly with its
factory default settings, in Basic operating mode.
You do not need to do anything. Please skip to the Power
Connections section below.
Standard default temperature and humidity settings
DMX, RDM and Remote Monitoring disabled

Other Operating Modes
Monitor Mode
As Basic mode, plus:
• RDM status reporting over RS485
• RDM configuration – settings may be changed remotely or at
the enclosure control panel
Control Mode
As Basic mode, plus:
Enclosure functions as a 1-channel DMX device, with
remote control of the lamp relay
o DMX level > 75% enables normal relay operation
(normally ON)
o DMX level < 25% disables normal relay operation
(relay turns OFF)
o This allows you to force a hard reset of the lamp relay
in the event of a luminaire malfunction
Control mode is recommended for show control
applications, but can be risky in live show operation, since
the DMX slot used for the enclosure MUST be kept high to
prevent the lamp relay from opening.
Service Mode
For trained service personnel only
Normal operation is suspended and the enclosure
functions as a 3-channel DMX device:
o Lamp Relay (Slot 1)
o Fans (Slot 2)
o Heater (Slot 3)
Service mode is ONLY for troubleshooting – DO NOT use
Service mode for normal operation.

(default 60°C, permissible range 55-70°C).
SET DELTA T (target difference between outside and inside temperature – drives fan speed)
(default ON (constant 100% fan speed), permissible range 2-10°C).
Note: A thermal emergency is when enclosure ventilation fails with the lamp on, in which case the temperature will
rise very quickly. To avoid nuisance tripping we recommend setting a higher Trip temperature, 60°C or above.
Set Lamp On Point
The lamp current at which DEC detects the luminaire/luminaire lamp is running. Default is 1 Amp, which allows for
equipment fans and power supplies to run without changing the air in the enclosure. Lamp on point may be set in
0.2 Amp increments between 0.2 Amps and 2.0 Amps.

Mounting The Luminaire
Moving lights from different manufacturers come with
various different mounting options, all of which will install
readily to Tornado’s luminaire mounts.
1. To mount the luminaire, first remove the two
mounting bars, by removing the 8mm nuts and
carriage bolts.
2. Choose the mounting method below:
Page 36
Tornado G4 User Manual 36
Omega Clamps
Most luminaires come with omega clamps of some kind,
and this is the easiest mounting method.
1. Simply bolt the omega clamp to the two luminaire
mounting bars. Note: This will probably work best in
one of the LOW positions (shown here), due to the
height of the omega brackets.
2. Check that the luminaire is centered and that the
ends of the mounting bars are parallel.
NOTE: In some cases, you may need to add a nut under the
omega clamp, to clear the omega handle.
NOTE: This mounting method may not provide maximum
rigidity. Some luminaires might be unsteady when stopping
at the end of rapid moves.
Example – Clay Paky Super Sharpy/Mythos.
1. Bolt the center hole of the mounting bar (wide side)
to the center hole of the omega clamp, using the M10
bolts provided. Using this side of the mounting bar
ensures that the height of the omega clamps will not
raise the luminaire too high in the enclosure.
2. Secure the omega clamp to the luminaire base using
the two quarter-turn fasteners provided.
Page 37
Tornado G4 User Manual 37
Screws
Many luminaire bases incorporate threaded holes for
mounting screws.
1. Simply screw into the luminaire base using the
appropriate screws (not supplied).
2. Check that the luminaire is centered and that the
ends of the mounting bars are parallel.
3. This is the most robust mounting method.
Tip: In some cases, you may find suitable threaded holes by
removing the rubber feet from the luminaire base.
Page 38
Tornado G4 User Manual 38
Quarter-Turn Fasteners (QTF)
Many luminaires with omega clamps do NOT have
threaded mounting holes. In this case:
1. Use a hammer to knock out the steel pin from the
omega clamp quarter-turn fasteners.
2. Remove the QTF from the omega clamp.
3. If there is a spacer on the QTF, remove and discard it
4. Re-assemble the QTF and replace the pin (tap home
with a hammer)
5. Use the QTFs to fasten the mounting bars to the
luminaire base.
TIP: If the QTFs are not tight, take them apart and add a
flat washer to pack out the length.
Discard spacers like this
Page 39
Tornado G4 User Manual 39
6. Re-assemble the QTF. NOTE: Some QTFs may have
spacers that are too wide (>12.7mm/.5in) to fit the
Tornado mounting slots. Discard these spacers.
7. Use the QTFs to secure the mounting bars to the
luminaire base.
Check that the luminaire is centered and that the ends of
the mounting bars are parallel.
Install Luminaire in the Tornado Base
Now take the luminaire, with mounting bars, and install
into the Tornado enclosure base, using the 8mm carriage
bolts, washers and nuts you removed at the start of this
process.
Page 40
Tornado G4 User Manual 40
Vari-Lite Truss Adapters
Vari-Lite luminaires come with a pair of proprietary truss
adapter brackets that snap onto ‘buttons’ on the base of
the luminaire.
1. Snap the adapter brackets onto the luminaire
buttons, following the manufacturer’s
instructions
2. Bolt the luminaire mounting bars to the truss
adapter brackets, using the M12 mounting
hardware supplied
3. Replace the whole assembly in the Tornado

Troubleshooting
Luminaire does not have power:
1. Check Luminaire power switch
2. Check luminaire is plugged into DEC4 luminaire
outlet
3. Check that enclosure feed circuit is on
4. Check DEC4 User Interface leds are on. If feed
circuit is on and UI leds are off, check feed wiring
to DEC terminals and meter DEC4 luminaire
outlet for power
5. If UI lamp led is on and DEC4 luminaire outlet is
live, there is a luminaire fault.
Enclosure overheats:
1. Is the luminaire connected to the DEC4 luminaire
receptacle? If the luminaire is powered
independently the controller has no way to know
when to turn on the exhaust fans!
2. Is the filter clogged or obstructed?
3. Check that the Fan led on the UI is on when the
luminaire is running. If not, then the luminaire is
probably not connected to the DEC (see 1).
4. If the fan led is on, check that the fan is running. If
not, check fan wiring. If wiring is ok, fan may be
faulty.
5. Check the UI display for RH (relative humidity)
message. If display reads RH 5%, RH 100%, or
RH###, there is a sensor fault. Contact Tempest
for a replacement sensor.
Dirt/Debris inside enclosure
1. Filter is either missing or damaged?
2. Filter is not properly seated
3. Side panels or back door is not firmly latched
Water in enclosure
1. Check the drain holes in the bottom of the
enclosure. If they become blocked, and water
that gets in cannot escape.
2. Check seals around the globe and globe collar
Fan LED is on but fans do not operate
The exhaust fan is protected by a 20mm 4A slow-blow
fuse on the DEC4 motherboard, and a secondary fuse
on the fan board. In very exceptional cases it is
possible that either fuse could fail. Check visually.
The fuse is protected with a clear resin sealant and
soldered to the circuit board. With care, you can desolder the fuse and replace it, but we recommend
replacing the DEC4 motherboard to maintain the
integrity of the board’s conformal coating.
Heater LED is on but heater does not operate
The heater is protected by a 20mm 10A slow-blow
fuse on the DEC4 motherboard. In very exceptional
cases it is possible that it could fail. Check visually.
The fuse is protected with a clear resin sealant and
soldered to the circuit board. With care, you can desolder the fuse and replace it, but we recommend

INSPECTION/WARRANTY/RETURNS.
A. Customer, at its sole expense, shall inspect all Goods promptly upon receipt and accept all Goods that conform to the
specifications or catalog. All claims for any alleged defect in or failure of the Goods or Seller's performance to conform to the
Contract, capable of discovery upon reasonable inspection, must be set forth in a written rejection notice detailing the alleged
non-conformity, and be received by Seller within thirty (30) calendar days of Customer's receipt of the Goods. Failure by
Customer to notify Seller of the alleged non-conformity within thirty (30) days will be conclusive proof that the Goods have
been received by Customer without defects or damage, and in the quantities specified on the bill of lading and shall constitute
an irrevocable acceptance of the Goods and a waiver of any such claim in connection with the Goods.
B. Seller warrants to Customer only that the Goods will be free from defects in material and workmanship at the time of
delivery and, subject to the exceptions and conditions set forth below, for the following period (the "Warranty Period"):
twelve (12) months from the date of shipment by Seller. Seller may provide additional years of warranty coverage beyond 12
months, at the rate of 2.5% of the net sale price per year, up to a total of four additional years’ coverage beyond the standard
12 month warranty period. Seller will remedy a defect as set forth in paragraph 7 D, below, (the "Warranty"). The Warranty is
subject to each of the following exceptions and conditions:
1. Customer must promptly (and in all events within the Warranty Period) notify Seller of any alleged defect in a written notice
(the "Notice") which shall set forth the quantity, catalog number, finish, original purchase order number, Seller's invoice
number on which Goods were originally billed and a statement of the alleged defect, along with digital photographs showing
such defects where feasible.
2. The Warranty shall not apply: (i) to any claimed defect that was capable of discovery upon reasonable inspection and
deemed to be waived under paragraph A, above; (ii) to any Goods that have been subject to misuse, abnormal service or
handling, or altered or modified in design or construction; (iii) to any Goods repaired or serviced by any person other than
Seller's authorized service personnel or to Goods installed other than according to installation instructions, or (iv) with respect
to normal wear and tear.
3. Seller makes no Warranty with respect to parts or components that are not the product of Seller, and specifically makes no
warranty whatsoever for equipment housed inside enclosure products manufactured by Seller.
4. The Warranty is Seller's exclusive warranty with respect to the Goods. Seller makes no warranties, guarantees or
representations, express or implied, to Customer except as set forth in this section. ALL OTHER WARRANTIES, EXPRESS OR
IMPLIED, INCLUDING, WITHOUT LIMITATION ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR USE OR FOR
A PARTICULAR PURPOSE, ARE HEREBY EXCLUDED AND DISCLAIMED.
C. Seller will accept the return of Goods properly rejected under paragraph A, above, or as to which Notice of an alleged
breach of Warranty has been timely given and such Goods may be returned to Seller, freight prepaid, but only upon
Customer's receipt of Seller's written return material authorization ("RMA") and shipping instructions. The RMA shall be void if
the Goods are not received within 45 days after issuance of the RMA. No deduction or credit in respect of any rejected or
returned Goods shall be taken until Customer has received Seller's further written deduction or credit/authorization following
Seller's inspection to confirm nonconformity or defect. Seller will charge to Customer any and all costs incurred by Seller in
connection with the handling, shipping, inspection and disposition of any returned Goods that are determined by Seller not to
have been nonconforming upon Delivery or as to which the warranty hereunder is not applicable.
D. UPON ANY PROPER RETURN PURSUANT TO PARAGRAPH C, ABOVE, WHETHER IN CONNECTION WITH A REJECTION OF
GOODS OR AN ALLEGED BREACH OF WARRANTY AND BASED UPON THE CONDITIONS SET FORTH IN THIS PARAGRAPH 7,
SELLER AGREES THAT IT WILL, AS THE SOLE AND EXCLUSIVE REMEDY UNDER THE CONTRACT OR OTHERWISE, FOR ANY
NONCONFORMITY OR BREACH OF WARRANTY, AND AT SELLER'S SOLE ELECTION: (i) REPAIR SUCH GOODS; OR (ii) REPLACE
SUCH GOODS.
