WARNING
Holatron Systems specializes in the design and manufacture of s tandard and custom electronic
control systems where reliability and error free data communication are critical. The transmitter
described in this manual is part of a system intended to remotely actuate pyrotechnic or other
hazardous devices, and the compon ents of this system have been carefully designed to
minimize the possibility of accidental actuation of such devices. Holatron’s design goal is to
ensure that data communication errors due to radio interference or to insufficient signal strength
due to low battery, exceeding specified range, or conductive objects in the signal path will result
in failure of intentional actuation rather than unintended actuation. Techniques used to achieve
this design goal are described in section 1. 9 . Though the probability of unintended actuation is
extremely small, it cannot be guaranteed to be zero. Therefore, it is important that the user
not enable the receiver until all persons who might be harmed by accidental actuation
are in a safe area .

This manual is divided into two sections. The first is a description of the system hardware. The
second covers the recommended operating and maintenance proced ure.
1.0 HARDWARE DESCRIPTION.
The model RFLS - 6HSXTX variable channel high speed UHF Transmitter is a low power
hand - held remote control transmitter which can actuate up to 72 separate devices
connected to six RFLS - 12HSRC receivers (12 cues, each), or to twelve RFLS - 9HSRC or
RFLS - 49HSRC receivers (6 cues, each), or to a combination thereof. Transmitted
commands actuate one of twelve possible output numbers and are transmitted over any
of six different digital channels. Each receiver contains a digital swit ch which is used to
select the channel which will activate the receiver. Six 12 - shot receivers or six pairs of 6 -
shot receivers are typically set to six separate channels for this purpose .
When first powered up, a transmitter is ready to transmit commands on its “base
channel”. The “base channel” setting is fixed in software at time of manufacture and
cannot be changed. A label displaying the base channel setting is affixed to the top of
the transmitter next to its antenna. If no more than 12 cues are bein g actuated per
transmitter, transmitters fixed to separate base channel numbers can transmit
simultaneously without interfering with each other. This permits up to six different
receivers or groups of receivers to be controlled by separate transmitters
sim ultaneously. Each transmitter will only actuate receivers whose digital channel
switches are set to select the same channel number as the controlling transmitter. Thus,
multiple transmitters may be used to simultaneously control different selected receiver s
even though all are operating on the same frequency. RFLS - 6HS XTX transmitters fixed
to the same base channel number should not be used simultaneously, as they will
interfere with each other and possibly result in failure - to - fire.
More than twelve separa te cues can be actuated from a single RFLS - 6HSXTX
transmitter in semi - automatic (single - shot) or automatic (machine - gun) mode by using
multiple digital channels. To actuate cues in semi - automatic mode, press the “ A ” button
repeatedly, as described in secti on 1.4. While armed, each button press fires the next
output in sequence, starting from output number 1 of the base channel . After output 12 is
fired, the next press switches the transmitter to the next higher channel number and fires
output 1 on the recei ver set to that channel. Firing continues through those 12 outputs,
after which the transmitter again switches to the next higher channel number, etc. After
output 12 is fired on channel 6, the transmitter switches to channel 1, and firing
continues from o utput 1 on that channel. To actuate cues in automatic mode , p ress the
“B” button , and firing will continue until it is released.

When used with RFLS - 9HSRC, RFLS - 9HSARC, RFLS - 49HSRC, RFLS - 49HSARC,
RFLS - 912HSRC, or RFLS - 912HSARC receivers, a range of ½ mil e can be achieved. All
inscriptions on the transmitter panel are luminescent to facilitate use of the transmitter in
a dark environment. The panel will continue to glow for two to three hours after being
exposed to a bright light source. The transmitter’s commands are digitally encoded and
amplitude modulated on a single carrier frequency of 418 MHz (or optionally 433.96
MHz). This frequency is controlled by a SAW (surface acoustic wave) device for
exceptional stability. No alignment or tuning procedures a re ever required to maintain
optimum performance. The modulated RF output occurs continuously while one of the
two transmit buttons is depressed. Resulting receiver output is continuous while the “A”
button command signal is being transmitted, and the receiver fires outputs in rapid - fire
mode at a rate selected by the FIRE RATE SELECTION SWITCH while the “B” button
command signal is being transmitted. The command signal is transmitted by amplitude
modulating the carrier to indicate to the receiver which cha nnel and which outputs are to
be actuated.
The user has access to the following components:
1.1 THE ANTENNA.
The RF signal is radiated by a quarter - wave flexible whip antenna which screws
onto the top end of the transmitter box. The transmitter should never be
operated without this antenna in place, as damage to the RF components
could result. Such operation will void the warranty.
Antennas with red rings are used for 433 MHz, and antennas with blue rings are
used for 418 MHz. Be careful not to overtighten the antenna when screwing it on,
as this could cause its mating connector to rotate and break its internal
connection. Rotation could also occur, with the same result, when subsequent
removal of an overtightened antenna is attempted. The recommended way to
install the antenna is to grasp it by its small diameter upper part and rotate gently
in a clockwise direction until increased resistance is felt. It need not be tight to
achieve a good electrical connection. When removing the antenna for storage,
observe the base of the mating connector to ensure that it is not rotating. If the
antenna is so tight that rotation is occurring, grasp the hex base of the mating
connector with long nose pliers, and then unscrew the antenna.
1.2 THE SAFETY LOCKING SWITCH.
The Saf ety Locking Switch is a miniature keylock with two positions, “Safe” and
“Xmtr Enabled”. In the “Safe” position no RF output occurs even if a button is
pressed. In the “Xmtr Enabled” position modulated RF output occurs
continuously while a button is presse d. Whether transmitting or not, a green
warning indicator near the switch flashes whenever the switch is in its “Enabled”
position and the battery voltage is above the low battery detect threshold.
Approximately 1 milliamp is drained continuously from the battery while the
transmitter is enabled and not transmitting. So this switch should always be
turned to the “Safe” position while the transmitter is not being used. Keys are
interchangeable, as all Holatron RFLS - 6HS XT and RFLS - 6HSXTX transmitters
are keye d the same.

5 of 1 6
Firing always commences at cue 1 of the transmitter’s base channel after the
transmitter has first been enabled. Thus the system can be reset to cue 1 of the
base channel at any time by turning this switch momentarily to “Safe” and then
back t o “Transmitter Enabled”. The system will be similarly reset if the
transmitter’s digital switch setting which selects automatic firing rate is changed
during operation.
1.3 THE “XMTR ENABLED” INDICATOR.
This green lamp, located at the “Enabled” position of t he lockswitch, warns the
user that transmission will occur when a button is pressed, and that battery drain
is occurring. It also verifies that battery voltage is adequate to transmit a signal
over the specified range.
When the transmitter is turned on (transmitter enabled) with the keylock switch,
battery status is indicated by the flashing of this lamp. It is of sufficiently high
intensity to be visible in direct sunlight and will flash intermittently in bursts of
one, two, or three flashes at a time if the battery has enough capacity to power
the transmitter. If no flashing occurs, the battery must be replaced before the
transmitter can be used reliably. Three flashes per burst indicate that the battery
has full capacity, two flashes indicate that its c apacity is beginning to diminish,
and one flash indicates that it is near the end of its useful lifetime in which case it
should be replaced immediately after the current use. Adequate transmitter
output to achieve the specified range will occur as long as the battery voltage is
above approximately 7.0 volts, but the battery voltage will drop rapidly at this
point.

6 of 1 6
1.4 THE FIRE BUTTONS.
These buttons are snap action dome switches under a sealed overlay, labeled
“Fire A” and “Fire B”, respectively. “Fire A” c auses cues to be fired in semi -
automatic (single - shot) mode, and “Fire B” fires cues in automatic (machine - gun)
mode. These buttons have a high spring constant which requires a firm
depression for actuation, decreasing the likelihood of accidental depressi on. The
enabled transmitter can be kept in a shirt or jacket pocket without fear of
accidental button depression.
The transmitter is idle while no buttons are pressed. Continuous transmission
occurs while a button is pressed .
Depression of either button fires the next receiver output after the one fired last.
For example, if output 3 had been fired last, pressing “Fire A” would cause output
4 to fire, etc. Depression of either button after firing output 12 will switch the
transmitter to the next channel a fter the previously selected one, and output 1 will
be fired on that channel. Thus, this transmitter can fire a series of up to 72
sequential shots spanning six 12 output receivers or twelve 6 output receivers or
a combination thereof. (See following diagr ams.) Note that after powering up the
transmitter, output 1 will be the first receiver output fired by a depression of either
transmitter button, and commands will be directed to receivers set to the
transmitter’s “base channel”.
Output firing pulses are stretched to a minimum duration of 0.6 seconds in the
receivers to ensure that all cues fire reliably, even when the fire button s are
pressed for a shorter period of time. Note that it is not necessary to wait for the
completion of the 0.6 second firing pu lse period before firing subsequent cues.
They can be fired as fast as the operator can press the button, provided that
each button depression lasts at least 0. 1 second , followed by at least 0.1 second
with the button released . If many transmitters are tra nsmitting simultaneously, it
may be necessary to depress a fire button slightly longer than 0.2 second in
order to ensure an output from the receiver.
NOTE: Firing always commences at the next cue after the last one fired when
resuming fire in the same mode (semi - automatic or automatic) as last
fired. When resuming fire in the opposite mode, firing will commence with
the next cue in most cases, but under some circumstances at very high
fire rates, a cue may be refired or skipped due to uncertanties in rece iver
– transmitter synchronization.

1.5 THE TRANSMIT INDICATOR.
This is a high intensity red indicator, visible in direct sunlight, that lights
continuously while the transmitter is generating RF output. It is located between
the two buttons. It will l ight even if the battery voltage is below the low battery
detect threshold.
1.6 THE BATTERY.
Power is supplied from an alkaline 9 volt battery, accessible beneath a slide - out
door on the back side of the transmitter. This battery should be replaced when
req uired by conditions described in section 1.3 above. In order to prevent the
possibility of damage due to battery leakage, the battery should always be
removed if the transmitter is to be stored for a prolonged period. Damage due to
battery leakage is not c overed under the warranty.
1.7 THE FIRE RATE SELECTION SWITCH.
A 16 position miniature rotary switch is accessible from the back of the
transmitter. The switch is on the left edge of the internal printed circuit board. It
can be set to positions 0 – 9 or A – F by rotation with a small screwdriver. The
switch selects automatic fire rate that will be transmitted while the “B” button is
pressed.

The available fire rates which can be selected a re described in the following
table. Holatron Systems can supply custom fire rates if required.
NOTE: F iring always commences at the next cue after the last one fired when
resuming fire in the same mode (semi - automatic or automatic) as last
fired . When re suming fire in the opposite mode, firing will commence with
the next cue in most cases, but under some circumstances at very high
fire rates, a cue may be refired or skipped due to uncertan t ies in receiver
– transmitter synchronization.
Upon the next butt on press after the fire rate switch has been changed,
f iring will commence at cue 1 of the transmitter’s base channel .

1.8 REMOTE FIRE JACK.
Transmitters that include this optional featu re can be actuated remotely through a
two conductor shielded cable plugged into a jack located on the left side of the
transmitter box. The jack accepts a standard 1/8” miniature stereo phone plug .
The cable’s shield connects to the plug’s “shell”, the red lead to the plug’s “tip”,
and the black lead to the plug’s “ring”.
The transmitter is actuated remotely by connecting the tip to the shell (red to
shield) to duplicate the action of the “ FIRE A ” button, and by connecting the ring
to the shell (black to s hield) to duplicate the action of the “ FIRE B ” button. The
transmitter’s FIRE buttons also remain operational while the cable is plugged in.
NOTE: T he transmitter should always be turned off when plugging in or
extracting the remote cable to ensure that no fire commands are
accidentally transmitted if jack contacts should be momentarily shorted
during the insertion or extraction .
1.9 RADIO INTERFERENCE REDUCTION.
For obvious safety reasons, Holatron's design goal is to ensure that data
communication errors due to radio interference or to insufficient signal strength
due to low battery, e xceeding specified range, or conductive objects in the signal
path will result in failure of intentional actuation rather than unintended actuation.
This goal is achieved by transmitting a 64 bit noise - tolerant code repeatedly while
a transmitter button is depressed. 6 0 of these bits must match the pattern
expected by the receiver . Thus, there is one chance in (2 to the 60
th
power) of an
actuation occurring due to reception of a random signal. Expressed in decimal
numbers, this is ( 1.1529 times 10 to the 18
st
power, or 11529 followed by 14
zeroes). This is a probability of 8.6736 times 10 to the - 19
th
power ( or a decimal
point followed by 18 zeroes followed by 86736 ). Though th is probability of
unintended actuation is extremely small, it cannot be guaranteed to be zero.
Therefore , it is important that the user not arm the receiver until all persons
who might be harmed by accidental actuation are in a safe area .
Additional prote ction is offered by use of 418 MHz as the operating frequency.
This frequency is sparsely used only by low power transmitters with a maximum
range of approximately 100 yards. It is not commonly used by auto security
systems, garage door openers, radio cont rol models, cordless or cellular
telephones, wireless microphones, or two way communications equipment.
Because this system operates in the UHF region, interference from lamp
dimmers, electrical discharges, and other natural sources is also minimal.
No co nfirmed cases of false triggering with this communications technology have
been reported to date.

2.1.1 With the receiver turned off and its a rm switch set to “ disarm ” ( RFLS -
49 HS RC) or “safe” (RFLS -9 HS RC & RFLS - 912HSRC ) , connect devices
to the receiver outputs.
2.1.2 With the a rm switch still in the previous position, turn on the receiver.
Verify a flashing green battery indicator on the receiver module . This
indicator will flash intermittently in bursts of one, two, or three flashes at a
time if the battery has enough capacity to power the receiver. If no
flashing occurs, the receiver cannot be used reliably. Three flashes per
burst indicate that the battery is fully charged, two flashes indicate that its
charge is beginning to diminish, and one flash indicates that it is near the
end of its useful charge, in which case it should be replaced immediately
after the current use.

2.1.3 Enable the transmitter, and with the receiver’s ARM switch in “safe” or
“disarm ed” position , perform a range test by observing the green
activity light on the receiver while pressing a transmitter button . There
should be no intervening conductive objects for most reliable operation.
All receivers must be elevated 12” or more above g round level to achieve
specified range. When transmitting over water , range will normally
exceed the specified value.
Range of the receiver is typically ½ mile, and its range can be tested with
the arm switch off by observing the green activity indicator while the
transmitter FIRE buttons are pressed. Verify that the transmitter battery is
not depleted by observing the flashing “Xmtr Enabled” light while not
pressing the FIRE buttons . (See section 1.3) Then turn the transmitter
lock switch back to “Safe” position.
2.1.4 When the area around the devices to be actuated is clear of persons who
might be injured by an accidental actuation, and after verifying that the
receiver’s green activity light is off (no radio signal is being detected), turn
the receiver’s ARM switch to its “ Armed ” position. Refer to the receiver
manual for the corresponding ar ming procedure .
WARNING - If the receiver’s green activity light is erratic or on
continuously , its output may be actuated immediately upon changing its
ARM switch to the “Armed” position .
2.1.5 Verify electrical continuity through the devices connected to the receiver
outputs. Continuity is tested on the RFLS -9 HS RC and RFLS - 49 HS RC
receiver s by pressing the test button. On the RFLS - 912HSRC receiver, it
is done by press ing the ARM toggle switch down into its “Test” position.
Lighted lamps indicate open circuits. It is recommended this be done with
the Arm S witch in the “Safe” or “Disarmed” position, but the test circuit will
also function in the “Armed” position.

2.1.6 Turn the transmitter lock switch to its “Enabled” position. Press the
appropriate button to actuate the desired receiver output channel. A
button must be depressed for at least 75 milliseconds to produce a
receiver output. It is never necessary to hold a transmit button down
longer than one second , however. If no actuation has occurred in this
period of time, none will occur, no matter how much longer the transmit
button is depressed. The receiver may be attempting to actuate a short
circuit , and damage co uld result.
The transmitter should be held with the antenna in a vertical orientation,
away from the body and other conductive objects to achieve maximum
range and communication reliability. Generally, the higher the transmitter
is held, the greater the r ange. Conductive objects such as chain - link
fences , aluminum bleachers, and automobiles in the transmission path
will reduce the range.
2.1.7 When finished, turn off the receiver, and turn the transmitter lockswitch
back to its “Safe” position to stop fu rther drain of the transmitter battery.
You may remove the antenna to make it easier to store the transmitter.
Observe the precautions in section 1.1 before removing the antenna. If
the transmitter is to be stored for a prolonged period, remove the battery
as described in section 1.6 above.
2.2 MAINTENANCE.
Since there are no calibration or tuning adjustments in the transmitter, the only
maintanance required is periodic replacement of the 9 volt battery. This should
be done at least once per year, or at the n ext opportunity if the “Xmtr Enabled”
light fails to flash when the transmitter is enabled.
The face of the transmitter, which is completely sealed, may be safely cleaned by
wiping with a damp cloth if care is taken not to get moisture into the lock switc h.
The battery compartment door and the junction between the front and back
panels are NOT water tight, however. The transmitter must never be immersed in
water.
