Holatron Systems specializes in the design and manufacture of standard 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 components 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 2.0. Though the probability of unintended
actuation is extremely small, it cannot be guaranteed to be zero. It is also possible that an
unexpected actuation can occur if another Holatron transmitter set to the same digital
channel and system code is being operated in the vicinity. Therefore, it is important that
the user not enable (arm) the receiver until all persons who might be harmed by
accidental actuation are in a safe area.
Equipment that has been damaged or contaminated internally with water or other substances
could be hazardous to operate, and it could generate an unintended actuation. The user must
consult with Holatron Systems before continuing use of such equipment.

This manual is divided into four sections. The first is a description of the system hardware. The
second describes radio interference suppression methods. The third lists system specifications.
The fourth covers the recommended operating and maintenance procedure.
1.0 HARDWARE DESCRIPTION.
The model XMTR12C high-speed 144-shot controller is a low power hand-held remote
control transmitter which can transmit commands over any of twelve different digital
channels.
The transmitter can be configured to be fixed or multi-channel multi-shot, and any fixed
channel setting or multi-channel range can be set from the keypad by pressing a special
code on the keys during the LED scan period immediately after power-up. Once set, this
configuration is saved in non-volatile memory even when power is off. The configuration
is defined by 3 parameters: “Base Channel”, “High Channel”, and “Low Channel”. Each
of these can be assigned the value 1 through 12 by pressing the appropriate key.
“Base Channel” is the channel on which the transmitter starts after power-on. “High
Channel” is the last channel the transmitter uses before cycling back to “Low Channel”
after firing cue 12 of the high channel. So if you want to configure a transmitter to be
fixed channel 3, for example, you would key in 3,3,3 after entering the special code. If
you wanted it to be a 72-shot unit operating on channels 1 through 6, you would key in
1,6,1. You can do much more elaborate configurations, too, such as making it an 84shot unit operating on channels 3 through 9 and starting on base channel 5 by keying in
5,9,3. The special code consists of pressing the 5 and 11 keys simultaneously. This
cannot occur accidentally, because it is very difficult to press these keys simultaneously
with one hand, and because this code is only sensed during the initial LED scan after
power-up
Operation can be switched on-the-fly to a different channel (within the configured range)
by pressing the Pwr / Rst button, followed by the number of the desired new channel.
On-the-fly channel changes are not saved in non-volatile memory. So operation will
revert to normal after power cycling the transmitter or after firing past cue 12.
Transmitters operating on separate digital channel numbers can transmit simultaneously
without interfering with each other. This permits up to twelve different receivers or
groups of receivers to be controlled by separate transmitters simultaneously. A
transmitter will only actuate receivers whose digital channel switches are set to the
same channel as the transmitter. Thus, multiple transmitters may be used to actuate
different selected receivers even though all operate on the same frequency.
Transmitters operating on the same digital channel number should not be used
simultaneously, as they will interfere with each other and possibly result in failure-to-fire.
This transmitter features an enhanced display mode which provides the following
indications:
Current cue number (to be fired next).
Current channel number (in single-shot mode).
Battery “fuel-gauge”.
Current firing mode (Safe, Single-shot, or Auto-fire).
Automatic firing rate (in Auto-fire mode).
Base-channel, High-channel, Low-channel configuration (at power-on).

When used with RFLS-491HSRC, RFLS-96HSRC, RFLS-96HSARC, RFLS-496HSRC,
RFLS-496HSARC, RFLS-912HSRC, RFLS-912HSARC, or RFLS-91212HSRC
receivers, a range of ½ mile 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 315 MHz (or 433.96 MHz in Europe). This frequency is synthesized
via phased-locked-loop from a quartz crystal for exceptional stability and immunity to
antenna proximity effects. No alignment or tuning procedures are ever required to
maintain optimum performance. The modulated RF output occurs continuously while a
transmit button is depressed. Resulting receiver output is continuous while the button
command signal is being transmitted. The command signal is transmitted by amplitude
modulating the carrier to indicate to the receiver which of the transmit buttons is
depressed.
The transmitter turns off its power automatically after 90 minutes of inactivity in order to
prevent accidental depletion of its batteries while in storage.
5 of 13
The user has access to the following components:
1.1 THE ANTENNA.
The RF signal is radiated by a quarter-wave reduced height helical 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 green rings are used for 315 MHz, with blue rings for 418 MHz,
and with red rings for 433 MHz. Be sure to use an antenna that matches the
transmitter frequency, or range will be seriously degraded. Be careful not to
overtighten the antenna when screwing it on, as this could put excessive stress
on the internal connections to the mating connector. 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 very tight
to achieve a good electrical connection. The antenna can be removed for
storage.
1.2 THE PWR / RST BUTTON.
This is a dual function button. It can turn the transmitter power on and off, or it
can initiate the transmitter’s reset / channel-change function, depending on how
and when it is pressed.
If the transmitter is off, pressing this button instantly turns power on, with the
transmitter initialized to cue 1 on its base channel. If the transmitter is on,
pressing and holding this button for at least 0.75 second turns power off.
The transmitter turns off its power automatically after 90 minutes of inactivity in
order to prevent accidental depletion of its batteries while in storage.
Pressing the Pwr / Rst button for less then 0.5 second while the transmitter is on
places the transmitter in channel-change mode, as indicated by a continuously
illuminated cue indicator. The transmitter will switch to the channel number
selected by the next numerical button press, and the cue number for that
channel will be reset to 1. If more than 4 seconds elapses without a button press
after channel-change mode is entered, the transmitter will revert to its previous
flashing mode without affecting channel or cue number. If the Pwr / Rst button is
pressed instead of a numeric button within the 4 second timeout period, channelchange mode is canceled, and a RESET command is transmitted to all receivers
set to the transmitter’s digital channel. Operation of the transmitter is also reset
to cue 1 This feature is useful for restarting automatic-fire sequences from cue 1.
It does not affect the function of the numeric keys or the ARM state of the
transmitter.
6 of 13
1.3 THE TRANSMITTER STATUS INDICATORS.
When the transmitter is on, one of the 12 cue indicators will flash to indicate the
transmitter mode (armed state), current cue number, current channel number,
selected automatic firing rate, and battery level.
1.3.1 SAFE MODE INDICATION.
The current cue number (next cue to be fired) is flashed with a green
color on the numeric keys when in this mode. The number of green
flashes per burst indicates the battery level as described in section 1.3.4
below. A separate orange flash indicates the current channel number. No
firing commands can be transmitted in this mode.
1.3.2 SINGLE-SHOT MODE INDICATION.
The current cue number (next cue to be fired) is flashed with a red color
on the numeric keys when in this mode. The number of red flashes per
burst indicates the battery level as described in section 1.3.4 below. A
separate orange flash indicates the current channel number. A single cue
is fired with each button press in this mode.
1.3.3 AUTO-FIRE MODE INDICATION.
In this mode the current cue number (next cue to be fired) is flashed with
a red color on the numeric keys continually at the selected firing rate, and
no orange channel indication flash or battery level indication occurs. Fire
commands will be transmitted in machine-gun fashion while the “Next
Fire” button is depressed.
1.3.4 BATTERY LEVEL INDICATION.
If not in AUTO-FIRE mode, the current cue number flashes in bursts of
red or green, depending on whether the transmitter is in SINGLE-SHOT
or SAFE mode, repeating once per second. The bursts indicate whether
the battery voltage is adequate by including one, two, three, or four
flashes. If fewer than two flashes per burst are occurring, the batteries
must be replaced before the transmitter can be used reliably. Four
flashes per burst indicate that the batteries have full capacity, three
flashes indicate that their capacity is beginning to diminish, and two
flashes indicate that they are near the end of their useful lifetime in which
case they should be replaced immediately after the current use.
Adequate transmitter output to achieve the specified range will occur as
long as the total series battery voltage is above approximately 2.0 volts,
but the battery voltages will drop rapidly at this point.
1.3.5 CHANNEL CHANGE MODE INDICATION.
The current cue number lights continuously while in channel-change
mode (after momentarily pressing the Pwr / Rst button). Pressing “Pwr /
Rst” again or a numeric button while in this mode will switch the
transmitter as described in section 1.2.
1.3.6 TRANSMISSION INDICATION.
The current cue number also serves as a transmit indicator in single shot
mode by lighting continuously red while transmission is occurring.
7 of 13
1.4 THE FIRE BUTTONS.
These buttons are snap action dome switches under a sealed overlay. When the
transmitter is off, all indicators are dark, and no signals can be transmitted even
if a button is pressed. When it is on, no transmission occurs (after the initial
power-on reset transmission) while no buttons are pressed. If armed (not in
SAFE mode), continuous transmission occurs while “Next Fire” or a numeric
button is pressed.
Pressing a numeric button while in single-shot mode fires the corresponding
receiver output on the current channel immediately.
Depression of “Next Fire” while in single-shot mode fires the next receiver output
(indicated by the illuminated numeric LED). For example, if output 3 had been
fired last, LED 4 would be illuminated, and pressing “Next Fire” would cause
output 4 to fire. If output 12 had been fired last, LED 1 would be illuminated, and
pressing “Next Fire” would cause output 1 on the next sequential channel to fire.
Thus, “Next Fire” can be used to fire a series of sequential shots. Note that after
powering up the transmitter, output 1 will be the first receiver output fired by a
depression of the “Next Fire” button.
In single-shot mode, the current cue will continue firing until the transmitter
button is released. In auto-fire (machine-gun) mode, the transmitter will continue
firing cues sequentially at the selected fire rate until the “Next Fire” button is
released. After firing cue 12, the transmitter will wrap around to cue 1 on the next
sequential channel and continue firing from there.
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 buttons 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 pulse 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 transmitting 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.
8 of 13
If in auto-fire mode, pressing a numeric button will change the auto-fire rate as
follows:
Button Auto-fire Rate Selection, Shots / Sec
1 1
2 2
3 3.03
4 4
5 5
6 5.88
7 7.62
8 7.62
9 10
10 10
11 14.3
12 20
The selected auto-fire rate is saved in non-volatile memory even while power is
off. So it does not need to be entered again unless the operator wishes to
change to a new rate.
1.5 THE ARM BUTTON.
Each successive depression of this button advances the transmitter to the next
of three firing modes: “Safe”, “Single-shot”, and “Auto-fire”. The next button
depression after “Auto-fire” returns the transmitter to “Safe” mode, and the
sequence then repeats. This button must be pressed after power-on to enable
transmission of firing commands since the transmitter always powers up in Safe
mode.
1.5.1 SAFE MODE.
The display operates as described in section 1.3.1. No firing commands
can be transmitted in this mode.
1.5.2 SINGLE-SHOT MODE.
The display operates as described in section 1.3.2. Firing commands in
this mode are transmitted as described in section 1.4.
1.5.3 AUTO-FIRE MODE.
The display operates as described in section 1.3.3. Firing commands in
this mode are transmitted as described in section 1.4.
9 of 13
1.6 THE BATTERIES.
Power is supplied from two 1.5 volt type AA batteries, accessible beneath a
slide-out door on the back side of the transmitter. These batteries should be
replaced when required by conditions described in section 1.3 above. In order to
prevent the possibility of damage due to battery leakage, the batteries should
always be removed when the transmitter is to be stored for a prolonged period.
Damage due to battery leakage is not covered under the warranty.
Be sure to observe proper battery polarity as marked inside the battery
compartment, as it is possible to install the batteries backwards, and this could
damage the transmitter, voiding the warranty.
The transmitter turns off its power automatically after 45 minutes of inactivity in
order to prevent accidental depletion of its batteries while in storage.
2.0 RADIO INTERFERENCE REDUCTION.
For obvious safety reasons, Holatron's top 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.
This goal is achieved by transmitting a 64 bit noise-tolerant code repeatedly
while a transmitter button is depressed. 60 of these bits must match the pattern
expected by the receiver. Thus, there is one chance in (2 to the 60
actuation occurring due to reception of a random signal. Expressed in decimal
numbers, this is (1.1529 times 10 to the 18th power, or 11529 followed by 14
zeroes). This is a probability of 8.6736 times 10 to the -19th power (or a decimal
point followed by 18 zeroes followed by 86736). Though this 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 protection is offered by use of 315 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, modern garage door openers, radio control 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 instances of unexpected actuation with this communications technology have
been reported to date, but the user must consider that radio is a shared medium.
It is very important to know what other wireless devices are operating in the
vicinity of this equipment. Interference from non-Holatron equipment can result in
diminished range or failure-to-fire, and interference from other Holatron
devices operating on the same channel and with the same system code
can result in unexpected actuation. To be protected from this possibility, the
user must purchase a proprietary system code from Holatron when ordering.

4.0 OPERATION AND MAINTENANCE.
This section describes the recommended operating procedure and maintenance for the
transmitter-receiver system.
4.1 OPERATION.
4.1.1 Turn on and arm the transmitter, and with the receiver’s ARM switch in
“safe” or “disarmed” position and no devices connected, perform a
range test by observing the green activity light on the receiver while
pressing a numeric transmitter button. An assistant may be needed to
observe the receiver activity light while you operate the transmitter. There
should be no intervening conductive objects for most reliable operation.
All receivers must be elevated 12” or more above ground level to achieve
full specified range. When transmitting over water, range will normally
exceed the specified value. Range of the receiver is typically ½ mile.
Verify that the transmitter battery is not depleted by observing the
flashing “Battery Level” light while not pressing the FIRE buttons. (See
section 1.3) Then turn the transmitter off.

4.1.2 With the receiver turned off and its arm switch set to “disarm” (RFLS496HSRC or RFLS-496HSARC) or “safe” (RFLS-96HSRC, RFLS96HSARC, RFLS-912HSRC, RFLS-912HSARC, or RFLS-91212HSRC),
connect devices to the receiver outputs.
4.1.3 With the arm switch still in the previous position, turn on the receiver.
Verify a flashing green battery indicator on the receiver module. On an
RFLS-912HSRC, RFLS-912HSARC, or RFLS-91212HSRC receiver, this
indicator will flash intermittently in bursts of two, three, or four flashes at a
time if the battery has enough capacity to power the receiver. If only one
flash occurs per burst, the receiver cannot be used reliably. Four flashes
per burst indicate that the battery is fully charged, three flashes indicate
that its charge is beginning to diminish, and two flashes indicates that it is
near the end of its useful charge, in which case it should be replaced
immediately after the current use. On the other receiver models, there will
be one fewer flash per burst for the same condition.
4.1.4 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 not erratic or illuminated continuously (no
radio signal is being detected), turn the receiver’s ARM switch to its
“Armed” position. Refer to the receiver manual for the detailed arming
procedure.
WARNING - If the receiver’s green activity light is erratic or on
continuously, its outputs may be actuated immediately upon changing its
ARM switch to the “Armed” position.
Do not arm a receiver with connected devices if it has been internally
contaminated with water or any other substance, as unexpected actuation
could occur due to conductive residues remaining on the circuit board. Contact
Holatron Syatems first.
4.1.5 Verify electrical continuity through the devices connected to the receiver
outputs. Continuity is tested on the RFLS-96HSRC, RFLS-96HSARC,
RFLS-496HSRC, and RFLS-496HSARC receivers by pressing the test
button. On the RFLS-912HSRC, RFLS-912HSARC, and RFLS91212HSRC receivers, it is done by pressing the ARM toggle switch
down into its “Test” position. Lighted lamps indicate open circuits. It is
recommended this be done with the Arm Switch in the “Safe” or
“Disarmed” position, but the test circuit will also function in the “Armed”
position.
12 of 13
4.1.6 Turn the transmitter on. Press the “Arm” button once to arm the
transmitter and verify a flashing red lamp, indicating that the transmitter is
armed. Press the appropriate numeric or “Next Fire” button to actuate the
desired receiver output. 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 could result If it is
desired to switch to a different channel, follow the instructions in the last
paragraph of section 1.2.
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 range. Conductive objects such as chain-link
fences, aluminum bleachers, electrical wires, earth mounds, and
automobiles in the transmission path will reduce the range.
4.1.7 When finished, turn off the receiver and the transmitter to stop further
drain of their batteries. You may remove the antenna to make it easier to
store the transmitter. If the transmitter is to be stored for a prolonged
period, remove the batteries as described in section 1.6 above.
4.2 MAINTENANCE.
Since there are no calibration or tuning adjustments in the transmitter, the only
maintanance required is periodic replacement of the AA batteries. They should
be replaced with a pair of new batteries at least once every two years, at the next
opportunity if the battery level indication is flashing 2 flashes per cycle, or
immediately if 1 flash per cycle.
The face of the transmitter, which is completely sealed, may be safely cleaned
by wiping with a damp cloth. 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.
