NTRODUCTION
important! READ AND SAVE THESE INSTRUCTIONS!
Thank you for selecting a JEM AF series fan.
The AF-1 and AF-2 fans are powerful machines designed for professional
and semi-professional use in clubs, TV studios, theaters and touring
contexts. They are suitable for a wide range of applications including
smoke and haze dispersal, sending smoke through ducting, wind effects
and cooling performers or equipment. When fans are used at high output
in conjunction with a smoke machine at low output, a perfect haze effect
can be produced.
Both fans have high quality sealed motors designed to withstand the high
condensation levels associated with close proximity smoke
AF-1 and AF-2 fans can be controlled using the remote control unit
supplied with each product or via DMX on a serial data link. They may be
interfaced with ZR12AL, ZR12DMX, ZR22STD, ZR22DMX and ZR33
smoke machines and Club Smoke System to allow simultaneous smoke
and fan operation.
When used in combination with smoke machines, etc., DMX control
allows atmospheric effects to be integrated in the light show directly from
the lighting console. The remote control allows variable fan speed in
continuous or timer operation. When using the built-in timer, operating
periods and intervals between operating periods can be set
independently.
The AF-1 fan can also be controlled using a 0 - 10 V analog controller.
The most recent version of this manual is available under Smoke in the
Support area of the Martin website at: http://www.martin.com

NSTALLING CONTROL HARDWARE
The AF-1 and AF-2 fans can be operated either using the JEM
multifunction remote control unit supplied with each machine, or via DMX
using a DMX control device and serial data link.
The AF-1 can also be operated using a 0 - 10 volt DC analog control
device. Up to four AF-1 fans can be linked in remote and 10 V analog
operation.
Remote control installation
To connect the remote control unit:
1. Power fa ns off.
2. Plug the XLR connector on the remote control cable into the REMOTE
IN plug on the connections plate (see “Connections panels” on page
4).
3. If linking multiple AF-1 fa ns, use suitable cable to connect the first
fan’s analog output to the next fan’s analog input, and continue
connecting fans output to input.
4. Reapply power.
The AF-2 touring frame available as an accessory includes a docking
station for the remote control unit (see illustration below). The remote
control can be fastened in place using the two thumbscrews provided,
and the remote cable wrapped around the brackets.
Installing control hardware 11
AF-1 10 V control installation
AF-1 fan speed can be controlled by connecting a suitable analog 0 - 10
volts DC controller via the ANALOG IN connector. Up to four machines
can be linked on an analog control link. To create an analo g control link:
1. Power fans off.
2. Connect a suitable cable to the controller’s output and the first fan’s
analog input.
3. Use suitable cable to connect the first fan’s analog output to the next
fan’s analog input, and continue connecting fans output to input.
4. Reapply power.
DMX installation
Up to 32 devices can be controlled on one DMX data link. Devices must
be ‘daisy-chained’ in one continuous line without branches. More devices
can be added and the link can be branched using an optically isolated
splitter/amplifier such as the Martin RS-485 Opto-Splitter (P/N 90758060).
DMX cable connection
A reliable DMX data connection requires suitable cable. Standard
microphone cable cannot transmit DMX data reliably over long runs. For
best results, use shielded cable with at least one twisted pair specifically
designed for RS-485 applications. Your Martin dealer can supply suitable
high quality cable in various lengths.
AF-1 and AF-2 fans both connect to a serial DMX data link via XLR
connectors:
• The AF-1 fan has three-pin XLR connectors for DMX IN and DMX OUT.
• The AF-2 fan has both three-pin and five-pin XLR connectors for DMX
IN and DMX OUT.
All DMX connectors on AF-1 and AF-2 fans are wired with pin 1 to ground,
pin 2 to signal - (cold), and pin 3 to signal + (hot). This is the standard pin
assignment for DMX devices.
12 AF-1 and AF-2 fans user man u al
To connect to devices with reversed polarity, use a phase-reversing
adaptor (P/N 11820006).
To connect the AF-1 to a device with a 5-pin output, use a 5-pin male to 3pin female XLR adaptor cable (P/N 11820005). To connect the AF-1 to a
device with a 5-pin input, use a 3-pin male to 5-pin female adaptor cable
(P/N 11820004).

DMX adaptors: connection pins and polarity
To connect the DMX data link:
1. Power all devices off.
2. Connect a data cable from the controller’s DMX data output to the first
device’s DMX input
3. Connect the DMX output of this device to the DMX input of the next
device.
4. Continue connecti ng up to a total of 32 devices in one single line,
output to input.
5. Terminate the link by inserting a male termination plug (available from
your Martin dealer: P/N 91613017) into the data output of the last
device. A termination plug is simply an XLR connector with a 120
Ohm, 0.25 W resistor soldered across pins 2 and 3.
Specifying DMX control channels
AF-1 and AF-2 fans use a single DMX control channel to receive
instructions from the controller. This control channel is the DMX address.
To control machines individuall y, each must have its own unique DMX
address. To control identical machines as a group, they can all be given
the same DMX address. They will then receive the same instructions and
should behave identically. Setting up identical fixtures with the same DMX
address can also be a good tool for troubleshooting unexpected behavior.
Installing control hardware 13
The DMX address on AF-1 and AF-2 fans can be set to any channel from
1 to 512 using DIP-switch pins 1 - 10:
1. Decide on an available DMX address for each machine.
2. Look up the DIP-switch settings using the Martin Address Calculator at
http://www.martin.dk/service/utilities/AddrCalc/index.asp, or look for
the address in the DIP-switch settings table on page 15. For example,
to set the DMX address to 101, you need to set DIP-switch pins 1, 3, 6
and 7 to ON, as shown in the illustration below:
3. Power the controller and all devices off.
4. For each device, set the DMX address by setting DIP-switch pins 1
through 10 to the ON (1) or OFF (0) position as listed in the table on
the next page. As an example, channel 101 is highlighted in the table.

DMX address DIP-switch settings
To use this table, first find the DMX address in the main block in the table.
Then read the settings for pins 1 - 5 to the left and read the settings for
pins 6 - 9 above the address. “0” means OFF and “1” means ON.
For example, to set the DMX address to 101, you need to set DIP-switch
pins 1, 3, 6 and 7 to ON, as highlighted in the table.

PERATION
Before powering on, check that the fan is correctly and safely installed.
Using fans with smoke machines
When using a fan in
combination with a
smoke machine, fog
machine or hazer,
place the fan behind
the machine, as
illustrated on the
right. Do not place
the fan in front of the
machine and direct
the output from the
machine into the fan,
as this will cause
undesirable residue
build-up and the fan
blades will degrade
the quality of the
smoke.
Using fans with smoke ducting
To avoid residue build-up and preserve smoke quality, connect fans to
smoke ducting using a Y-shaped arrangement, placing the fan on one arm
of the Y and the smoke machine on the other.

Multifunction controller overview
A INSTANT FAN OPERATION BUTTON – Press to run the fan
at the speed set on the fan speed control.
B STANDBY – Puts the fan into standby mode. Must be set
to ON to operate in any mode.
C TIMER VALUE BUTTON – When timer is active, adjusts
timer values by a factor of 8 (i.e. a 5 second run time
becomes 40 seconds and a 10 second delay time
becomes 1 minute 20 seconds).
D TIMER ENGAGE – Engages the timer to run the fan
according to the timer settings.
E SPEED – Sets fan speed from minimum to maximum.
F POWER LED – Lights when power is on.
G DELAY TIME CONTROL – Sets intervals between
operating periods during timer-controlled operation.
H CYCLE LED – Lights during timer-controlled operation.
I RUN TIME CONTROL – Sets duration of operating periods
during timer-controlled operation.
The multifunction remote control unit supplied with the AF-1 and AF-2
fans allows instant or timer-controlled fan operation and airflow control.
The unit also gives feedback on the status of the machine.
Operation 17
To set timer operation using the remote control:
1. Set the desired amount of airflow using the SPEED control
2. Set intervals between operating periods by setting the DELAY control
to between 1 and 9.
3. Set duration of operating periods by setting the RUN control to
between 1 and 9.
4. Set the STANDBY button to ON
5. Set the TIMER ON button to ON.
The CYCLE LED lights when the timer function is active.
To extend timer settings, press the X8 button. This will multiply both RUN
and DELAY times by 8.
DMX control
Fan speed on the AF-1 and AF-2 fans can be controlled using a DMX
controller.
DMX controller operation
When a fan is powered on, the Data LED next to the DIP-switch will light
when a valid DMX signal is received.
Increase the value on the machine’s DMX control channel to increase fan
speed as shown below:

ERVICE AND MAINTENANCE
Any service procedure not described here should be referred to a
qualified technician.
Warning! Disconnect the fan from power before removing any grills or
covers.
Cleaning
Clean the outside of the fan with a damp cloth only. Do not use solvents.
Periodic cleaning of the fan blades and grills is necessary to maintain
peak performance. Cleaning intervals will depend on the operating
environment. Inspect the fan regularly for dust and smoke residue
buildup, and clean as soon as there is significant dirt buildup on fan
blades or at the first signs that airflow through grills may be restricted.
Use a soft brush and vacuum to clean grills and fan blades.
AF-1 cleaning access
1. Disconnect the fan
from power.
2. Remove the four
cross-head screws (A)
as illustrated, and lift
the grill/motor
assembly clear of the
housing. The motor
cable (B) will remain
attached to the motor
and the housing.
Avoid straining the
cable.
3. After cleaning, replace
the grill and screws,
ensuring that screws
are securely
tightened.
Service and maintenance 19
AF-2 cleaning access
1. Disconnect the fan from power.
2. Remove the 16 cross-head screws from the covers (see illustra tion
above), and remove the covers.
3. Reaching into the fan housing for
access to the locking nuts,
remove the four 6mm Allen
screws holding the front grill (see
illustration on right), collecting all
washers and grommets for reuse.
Note: the front grill is on the
opposite side from the fan motor.
It should be possible to clean the
machine without removing the
rear grill that holds the fan motor.
4. After cleaning, replace the screws and front grill. Reassemble exactly
as shown in the next illustration, making sure that the rubber
20 AF-1 and AF-2 fans user man u al
grommets (A) are seated in the fan housing (B). If this assembly
A
B
sequence is not respected, the AF-2 will be excessively noisy.
Replacing the main fuse
The main fuse can be replaced by the user if necessary. An indication that
the main fuse may have blown is that the Power LED (on the AF -1 only) or
the Data status LED (on AF-1 and AF-2 fans) does not light when:
• power is applied, and
• the remote control or a valid DMX signal is present.
Never bypass the fuse or replace it with one of another size or rating.
To replace the main fuse:
1. Disconnect the power cable from the fan.
2. Use a screwdriver to lever the fuseholder out
of the power inlet socket (see illustration).
3. Replace the fuse with one of the same rating
and type. Fuse details are given on the serial
number label and in the Specifications
sections of this manual.
4. Replace the fuseholder and reconnect to power.
If the fuse blows repeatedly, disconnect the machine from power and from
control equipment and contact your Martin/JEM dealer for service.
