AN INTRODUCTION TO SMOKE TECHNOLOGY
Smoke Machine Markets
Jem /Martin smoke machines are categorised into 2 ranges: The Professional and the Club /DJ range.
If a product is branded as a “Martin” product this is aimed at the Club/DJ market.
All products branded as a “JEM” product are classed as Professional and are aimed at the higher end touring /
installation market.
All JEM /Martin Smoke products can be used across both of the different markets without any compromise of
performance or features.
Smoke machine principles:
All JEM /Martin conventional smoke machines utilise the same technology:
In Brief:
When the run button on the remote is pressed, smoke fluid is pumped from a removable container
situated within the machine via the flexible fluid pipe into an oscillating piston pump.
The fluid passes through the pump and enters the heat exchanger were the fluid is vaporised and
exits as thick, white smoke.
The heat exchanger is comprised of a heating element and a coil of copper or steel tubing between 3 and 6
metres in length. This is cast into a mass of aluminium.
The heat exchanger is heated via the heating element.
This is controlled by a J Type thermocouple fitted to the heat exchanger.
The temperature is determined by the calibration ofthe main control PCB.
Once the working temperature is reached, the main control PCB will allow the pump to be operated and the
machine will now be ready to run.
Haze machine principles:
The JEM ZR24/7 and Magnum Hazer work on the same smoke generation principles as the JEM /Martin
smoke machines.
The only difference is the smoke output on a hazer exits into a metal chamber where there is a fan creating a
fast moving air stream. This air stream disperses the smoke output and creates the haze.
Again the principles are identical to that of a conventional smoke machine.
There is a pump, heat exchange, PCBs and onboard controls. The major difference is the air chamber.
A radial fan is used with this system. It is used to allow the exiting smoke to have the maximum dispersal.
As with several of the smoke machines, the haze machine has a low fluid shut off system. This is an
electronic temperature control device that measures the temperature of the heat exchange over a short
period. If the temperature has not changed but the unit has been pumping; the unit will assume that the
system has run out of fluid and shut down. This prevents the system from running dry and burning out
the pump.

CE mark
All products that are produced by JEM / Martin carry the CE Certification.
These products meet the requirements of the following EC Standards and as such, comply with the EMC
(Electromagnetic Compatibility) and LVD (Low Voltage Directives),directives of the European Community:
EN 50 081-1 1992 Generic Emission Standard for domestic and light Industrial environments.
EN 50 082-1 1992 Generic Immunity Standard for domestic and light Industrial environments.
EN 60 335-1 1995 Safety of household and similar electrical appliances
These standards reference the following European standards:
Emissions:
EN 55 022 /B RF voltage and field strength
EN 60 555 Harmonic current content
EN 55 014 RF voltage (discontinuous)
Immunity:
IEC 801-2Electrostatic discharge to case
IEC 801-4Common mode fast transients
These standards also meet the requirements of CISPR 22.
JEM did not carry the CE mark on products that were produced prior to 1995.
These products can be identified by either the DIN/XLR socket on the rear or top of the unit or the Mains PCB:
If the unit has a 5 pin DIN or a 4 pin XLR without the CE text on the rear, the unit is classed as NON-CE.
If the PCB has a 12 pin Molex connector fitted to it, this is classed as a NON-CE unit.

What can my machine do?
The AF-2is a compact but powerful fan designed with clubs, studios, theatres and touring applications in mind.
The AF-2features DMX input as standard and can be installed on a ceiling, in a truss or can be floor standing.
It can be used alone or as part of a complete fog system by linking with other Jem machines using DMX.
The fan unit incorporates a very high quality scaled fan motor to withstand high condensation levels associated
with close proximity to fog.
The AF-2 is constructed from mainly aluminium sheet for minimal weight, without compromising ruggedness.
If you want extra protection for the AF-2 the accessory Touring Frame is available. This at the same time acts
as a floor stand, and adds the ability to mount the remote control.
An analogue remote control is provided enabling variable output and timer control of fan speed allowing you to
adjust to every situation.
