Access Clearance
Observe these minimum access clearances shown around
your enclosure
Mounting Hardware Options
Mounting Bolts
Each Enclosure must be mounted with at least FOUR
points. Larger Enclosures must be mounted with SIX
points.
All mountings must be made using the M12
threaded holes on the top and bottom of the
enclosure.
Use an 8mm hex key to secure the M12 socket cap
screws provided.
Tempest recommends the use of stainless steel
mounting hardware.
IMPORTANT SAFETY NOTICE
Installer must ensure that all mounting points are secure
and conform to local safety regulations. Tempest Lighting
Inc. accepts no responsibility for damage or injury arising
from inappropriate or unsafe installation.
Mounting Options – Unistrut Kit
If mounting positions for the corner bolts are not
convenient, use the Unistrut Kit (55.UR.xxx) to add two
Unistrut rails and Unistrut spring nuts to the top or
bottom of the enclosure.
Using the spring nuts, the enclosure may now be
attached at any point along the Unistrut rails.

Installing Ducts and Fans
The excellent noise attenuation levels you can achieve
using Tacit enclosures depend on the acoustic separation
of the audience from the enclosure’s exhaust fan(s).
Tempest recommends locating the exhaust fan in a
separate location, ideally on the other side of a wall from
the audience space. Where this is not possible, it will be
necessary to install acoustic insulation between the
exhaust fan and the audience space.
The installer is responsible for installing ducting between
the enclosure exhaust duct ring and the fan location.
For best acoustic performance we recommend also
ducting inlet air from an adjoining space.
Duct Criteria
There are many types of duct available, and the duct
choices can significantly affect cooling and acoustic
performance. The lower the static pressure in the
installed ductwork, the slower the exhaust fan will be
able to run, and the quieter it will be.
Tempest recommends using circular steel duct, with large
radius corners and of at least 30cm/12in diameter, for
distances up to 8m/25ft. For longer distances, consult an
air-handling specialist. For shorter runs, and runs that are
relatively straight, 25cm/10” duct may be adequate.
Ducting should allow for minimum airflow rates:
Tacit 200-300: 500cfm, 0.25m3/S
Tacit 350 and up: 1000cfm, 0.5m3/S
Note that smaller Tacit models are supplied with 10”/254mm duct
adapter rings, while larger units have 12”/305mm adapters. It is
always ok to use ducts with a larger diameter than the duct adapter
ring.
AVOID USING FLEXIBLE DUCTS -THEY IMPOSE MUCH HIGHER STATIC
PRESSURE THAN SMOOTH-SIDED STEEL DUCTS. IF YOU MUST USE A
FLEXIBLE DUCT, USE A DUCT AT LEAST TWO SIZES LARGER AND PULL
IT AS TIGHT AS YOU CAN.
Exhaust Duct and Fan Kit
Your Tacit enclosure is supplied with a fan assembly to be
mounted at a remote location (described above).
1. Mount the fan kit either on the side of a
building return air duct, or blowing into an
open space such as a roof void.
2. Connect the enclosure exhaust duct adapter to
the fan kit using ducting described above.
3. Pull a 3-conductor flexible wire (16ga/1.5mm
2
)
through the exhaust duct and connect one end
to the fan terminals.
4. Connect the enclosure end to the fan terminals
on the DEC4 fan controller board (see below)
Example:
Inlet air is drawn from an adjoining room or
ceiling void.
Exhaust air is ducted to the enclosure exhaust
fan, feeding into a building air return duct

Inlet Duct
Wherever feasible, draw inlet air from an adjoining space,
using the same duct type specified for the exhaust
airflow.
DO NOT feed the inlet directly from a building air supply –
this may be too cold OR too hot, depending on location
and air conditioning installation type. It is better to draw
inlet air from an adjoining insulated roof space or airconditioned room. Incoming air temperature should not
exceed 25-30°C – the warmer it is, the harder the fan
must work to cool the projector, and the louder it will be.
Flexible Inlet Duct/Baffle
If it is not feasible to draw inlet air from an adjoining
space, the next-best solution is to use a length of padded
flexible hose, laid out in an ‘S’ configuration above the
ceiling tile to baffle any noise that may escape from the
inlet opening.

Wiring the Enclosure
Power Wiring
SAFETY NOTICE
All power wiring must be performed by a competent electrician, appropriately licensed in the jurisdiction where the installation takes
place. All electrical work must be done in full compliance with all electrical and safety norms applicable to the installation site. Isolate
all power feeds before opening the enclosure.
Tempest Lighting, Inc., its employees and agents will not be held responsible for damage or injury caused by disregarding this notice.
Electrical Standards
Important:
Enclosure model numbers including .US are for use in countries using US and Japanese style electrical systems:
200-208VAC 50/60Hz
Enclosure model numbers including .IN are for use in countries using European style electrical systems:
220-250VAC 50/60Hz
Note:
(1) Fans are rated 200-250V, dependent on electrical standard.
(2) Electronics are autosensing for any voltage 90-265VAC, 50/60Hz
Page 14
Tacit G4 User Manual 14
Wiring Access
Locate the two Conduit entry holes on the top panel of
the enclosure:
Conduit openings accept PG21 (International) and ¾” NPT
(North America) conduit fittings.
Use permanent or flexible conduit to connect power and
signal cables to your Tacit enclosure.
ALWAYS RUN POWER AND SIGNAL CABLES IN SEPARATE
CONDUITS.
NOTE: Layout of Tacit models may differ slightly

One or Two Power Circuits?
Tempest enclosures may be wired on single or double
circuit supplies. On a single feed, both enclosure and
projector are permanently on. With a split (double) feed
supply, you can switch off the projector when not in use,
while the enclosure continues to protect it 24/7.
Tip: most people use single feed.
Single Feed
Enclosure and projector are permanently on.
Enclosure and Projector must be rated for the
same voltage.
Supply must be rated for projector current plus
150 watts.
Supply must be permanently ON.
Split feed
Enclosure power must be permanently ON.
Projector power may be switched off.
Enclosure power must be rated for 650 watts.
Projector power must be rated for the projector (see
projector manual).
Projector and enclosure power must be same voltage.
For single feed wiring, no modification to the DEC4
Controller motherboard is needed.
IMPORTANT:
For split feed wiring, use a side cutter to cut both AC links at both
ends:

Wire Path
Pull incoming AC supply wires through the plastic
grommets shown here.
For clarity, the following diagrams do not show factory
wiring.
Single or Three-Phase?
Most Tacit enclosures require a single phase 200-240VAC
AC supply (208V – 2 hots @120V in US).
In just a few cases, presently:
Some high-output Barco projectors, eg HDQ
Some Christie projectors with external ballast,
eg Roadie 45K, CP4230
…a 3-phase AC supply is required.
Three phase Split Feed
IMPORTANT: Three-phase systems with split feed MUST be factory
configured. You CANNOT change a 3-phase Tacit between single and
split feed in the field.
AC Supply Voltage
Tempest Tacit enclosures require supply voltage in the
nominal range 200-250VAC, 50/60Hz.
Tempest G4 enclosures are very tolerant of supply
voltage variations:
DEC4 controller has a universal power supply
and operates on 90-265VAC
All enclosure fans are 120VAC, and are
proportionately controlled up to their
maximum rated voltage (120V). So cooling
performance will not be affected when running on any
supply that exceeds 125VAC between line and neutral (or
between hots in North America)
Enclosure heaters are rated 200-250VAC. Heaters are
thermostatically controlled, so while some degradation is
possible on low supply voltages, this will be compensated
by heater duty cycle.

Tacit Fan Speed Capacitor
The enclosure fan is over-dimensioned for the required
cooling airflow, and is slowed down by a capacitor wired
in series between the DEC4 Live fan terminal and the fan.
This reduces fan noise, but also airflow, and it is possible
that the capacitor value may need to be adjusted to
optimize for the best balance between airflow (cooling)
and fan noise.
Each installation is different: Tempest includes with your
enclosure capacitors with higher (more airflow) or lower
(less noise) ratings, which you may install as needed.

Remote Monitoring Connections
Tempest G4 enclosures optionally support three 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)
3. Grouped via RS485, using DMX/RDM – see next
page
Requires one 51.485 RS485 board per enclosure

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.
Projector 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. In 3-phase
enclosures this is augmented by a 4-pole contactor.
You may use DMX512 (a popular entertainment industry
protocol running on RS485, originally intended to control
lighting system dimmers) to control power to the projector
inside the enclosure. This is very useful in hot locations,
where the projector may be stressed by being held in
standby mode all day under hot sun. By powering the
projector 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 projectors.
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 amd
management using Tempest’s TEMP protocol.

DEC4 Main Functions
1. Sense current to projector (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 projector 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 projector is idle
DEC3.3 constantly monitors the following parameters:
Projector/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
Best for standalone operation

Other Operating Modes
TEMP Mode
TEMP Operation is now supported with DMX Mode set to BASIC
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 projector 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 projector/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.
Reset Lamp Hours
Reset each time you change the lamp in the projector.

Mounting the Projector
Enclosure Configuration
Landscape Configurations
Tacit’s projector slide may be factory configured as
follows:
Tabletop – tray down – projector sits on its feet
Ceiling – Tray up – projector hangs from the
tray, feet up
Front Slide – projector slides out of the
enclosure front door
Rear Slide – projector slides out of the back
door
This configuration can be changed on site, but it’s a lot of
work!
We recommend making sure the system is ordered with
the desired configuration set up in the factory.
Portrait Configurations
Most Tacit enclosures may be specified in portrait format
(this depends on the desired projector being approved for
portrait orientation).
Most projectors that are approved for portrait operation
may only be used in one orientation (feet left or feet
right). Your Tacit enclosure will be factory configured to
suit the specified projector orientation.
Tacit Portrait enclosures may be manufactured with front
or rear slide, just like landscape enclosures.

The lamp exhaust from these projectors requires a special
chimney (provided) to direct the hot air into the
enclosure exhaust fan.
Adjust so that the rubber bulb seal around the chimney is
seated snugly to the projector lamp door.
Failure to follow this step will very likely lead to hot air
recirculating and serious overheating.

Routine Maintenance
Check the following every six months:
Clean Port Glass
Clean port glass using a window cleaning fluid or
detergent. Use a soft, lint free cloth.
Check Filter
In most cases the filter will be good for 1-2 years, but
this may vary a lot, depending on the source of inlet air
and how much the projector is used.
If the filter becomes clogged the temperature inside
the enclosure will start to rise. This is an indication that
the filter must be cleaned or possibly replaced.
Part Numbers:
56.IFL.11 Replacement Inlet Filter Tacit 56.200 Series
56.IFL.13 Replacement Inlet Filter Tacit 56.250 and up
To clean or replace filter
1. Remove the four filter clamp thumb nuts
2. The filter clamp will drop out
3. Remove filter
4. Wash filter with warm water and mild
detergent if needed
5. Dry filter
6. Replace

Troubleshooting
Projector does not have power:
1. Check Projector power switch
2. Check projector is plugged into DEC4 projector
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 projector outlet
for power
5. If UI lamp led is on and DEC4 projector outlet is
live, there is a projector fault.
Enclosure overheats:
1. Is the projector connected to the DEC4 projector
receptacle? If the projector 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
projector is running. If not, then the projector 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
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
replacing the DEC4 motherboard to maintain the
integrity of the board’s conformal coating.
