SAFETY SUMMARY
The following are WARNINGS and CAUTIONS, contained throughout this manual and
are repeated here for emphasis. All personnel engaged in the handling, firing, and
storage of the system covered in this manual must fully understand these WARNINGS
and CAUTIONS, and procedures by which hazardous conditions are to be reduced or
eliminated. Also listed are general safety precautions that are not related to any specific
procedures and therefore don't appear elsewhere in this publication. These are
recommended precautions that personnel must understand and apply during many
phases of operation and maintenance.
WARNING
Never rely on the equipment for your safety.
WARNING
Use of this system and its components must be restricted to personnel
qualified and experienced in the field of explosives and detonating devices. Under no
circumstances shall untrained personnel attempt to use this manual as a text for selfteaching.
WARNING
This system and its components should be stored in a secure area with
no access to unauthorized personnel. This system can be used in conjunction with
explosives as a deadly weapon.
WARNING
These radios contain batteries. The potential for activation is always
present whether or not antennas are attached to the units.
WARNING
Employ standard blasting system safety standards when using this
equipment with explosives.
WARNING
Lightning induced energy, caused by electrical storms, can detonate
explosives. In the interest of safety, blasting on land, water and underground should be
suspended and all personnel should be evacuated to a safe distance from the blast
area whenever lightning storms are in the vicinity. Dangerous levels of static electricity
can build up in the atmosphere. These levels can be sufficient to detonate explosives.
WARNING
Radio frequency energy of sufficient magnitude can cause blasting
caps to detonate.
WARNING
To eliminate long wire runs, and to make the "shoot" from a safe
distance, the Remote Firing Device uses low energy level radio frequency
transmissions.
WARNING
The Controller Unit has a 5 watt output power level (5 mile transmit
range). The Controller Unit should be considered DANGEROUS and NEVER be
operated within 100 feet (minimum) of blasting caps, wires connected to blasting caps,
or other electrically initiated explosives devices. Do NOT apply power to the Controller
Unit unless the operator is at least 100 feet from blasting caps, wires connected to
blasting caps, or explosives.
RFD OPERATOR MANUAL
viii
WARNING
Do not connect a blasting cap to a Detonator Unit unless the green
SAFE light is on, the red ARMED light is off, and the yellow ON/LOW BATT light is on
steady. This indicates there is no voltage on the binding posts, the binding posts are
electically isolated from the firing capacitor, the binding posts are shunted to each other,
and the battery is not low.
WARNING
Ensure that blasting caps are not connected to any of the Detonator
Units during bench test.
WARNING
This is a sensitive electronic radio system and it may be damaged.
WARNING
Detonator Units have been tested and are safe to use near explosives
and blasting caps. The low level of transmit power (less than 100 milliwatts) used by
the Detonator Unit will NOT detonate blasting caps, even if they are directly connected
to the Detonator Unit's antenna terminals. The Detonator Unit transmission range is
limited - approximately 1,000 feet. The Detonator Units will receive and will act upon
commands from the Controller Unit which may be located in the line of site up to 5 miles
away. The controller Unit need not and may not receive verification from a Detonator
Unit which is more than 1,000 feet away.
CAUTION
Do not assume the Disarm command has been received by the
Detonator Unit unless DISARMED status is confirmed with a steady DISARMED light
for that Detonator Unit on the Controller Unit display panel. If distance appears to be
the problem, move closer to the Detonator Unit following standard procedures for this
type of situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedly
as the Detonator Unit is approached. Maintain a safe distance from the Detonator Unit.
Do not approach the Detonator Unit until Disarmed status is confirmed with a steady
DISARMED light for that Detonator Unit on the Controller Unit display panel. Under no
conditions should the “FIRE” switch be pressed as the Detonator Unit is approached.
Do not bring the Controller Unit closer than 100 feet to blasting caps, wires connected to
blasting caps, or other explosives.
CAUTION
All units must be thouroughly tested and the batteries fully charged
prior to operational use.
CAUTION
Unequal air pressure inside the Controller Unit may affect the
operation of membrane switch keypad. Extreme pressure differentials may irreversibly
damage the keypad and/or cases.
CAUTION Vents in all units should be momentarily opened and closed
immediately before use.
CAUTION Do not open a vent if there is water on or near the vent. Take
necessary precautions to ensure water does not enter the vent.
CAUTION
Do not use any component that is damaged, suspected of being
damaged, or is not able to operate as designed. The safety of the operation could be
compromised.

1. INTRODUCTION.
1.1.
PURPOSE.
1.1.1.
The primary purpose of this manual is to provide descriptive information,
operational information, instructions in assembly, and instructions in testing and
preparation for operational or training use of the Remote Firing Device (RFD).
1.1.2.
The Remote Firing Device (RFD) is used to activate electric detonator
devices. The System is strictly an electronic device, containing no explosive. The
Controller Unit shall be operated from 100 feet to five miles from the explosive. The
Detonator Unit shall be placed at the explosive site, with a two-conductor firing line
running to the explosive. The Controller Unit communicates to the Detonator Unit
through a two-way RF transmitter data link, for a line of site distance of 5 miles. The
Detonator Unit can return communication for a distance of 1,000 feet.
1.2.
EXPLOSIVES HANDLING PRACTICES.
1.2.1.
The transmitting output power of a Detonator Unit is limited to less than 100
milliwatts. The Detonator Unit’s radio frequency power output level is well below the
safe energy limits cited by the IME (Institute for Manufacturers of Explosives) to
detonate a single blasting cap via radio frequency energy. This safe power level has
been established by IME in Pamphlet 20, titled “Safety Guide for the Prevention of
Radio Frequency Radiation Hazards In the Use of Commercial Electric Detonators
(Blasting Caps).”
1.3.
STORAGE AND ENVIRONMENTAL CONDITIONS.
1.3.1.
The Controller Unit and Detonator Unit have manual operated vents. The
vents should always be CLOSED during air transport, underwater transport, storage
and operational use to prevent moisture intake. The operator should momentarily open
and close the vent after the unit has been subjected to changes in elevation or depth.
This equalizes pressure within the case to the outside environment. DO NOT open the
vent if there is water on or near the vent. Towel dry prior to opening vents. The vents
should be OPEN, when stored in a dry hot environment.
1.3.2.
The Controller Unit and Detonator Unit (with vents closed) are airtight to an
altitude of 30,000 feet and watertight to a depth of 100 feet.

the switch again and the yellow SELECT light for that Detonator Unit will be turned off
indicating the Detonator Unit is not selected.
2.3.4.
Request Detonator Unit Status. Depress “STATUS” switch to transmit a
status request signal to the selected Detonator Units. The selected Detonator Units will
transmit their current status to the Controller Unit. If none of the Detonator Units are
selected, the Controller Unit will request status from all eight Detonator Units. If the
Controller Unit is within range of the Detonator Unit transmitter, the status of the
selected Detonator Unit will be presented on the display panel with a steady light. If the
Controller Unit is out of range of the Detonator Unit transmitter, the status will be
assumed from the last command sent to that Detonator Unit. In that case the assumed
status of the Detonator Unit will flash on the display panel.
2.3.5.
Arm the Detonator Unit. Depress the “ARM” switch for 1/2 second and the
Controller Unit will transmit the Arm command to the selected Detonator Units. The red
ARMED light at the selected Detonator Units will flash on the Controller Unit display
panel until the firing capacitor charging time is completed. The Controller Unit then
requests status of the selected Detonator Units. If the Controller Unit is within range of
the selected Detonator Unit transmitter, the ARMED red light for that Detonator Unit will
be on steady on the Controller Unit display panel. If the Controller Unit is out of range
of the selected Detonator Unit transmitter, the red ARMED light for that Detonator Unit
will continue to flash on the Controller Unit display panel. If the Fire command is not
sent within 60 seconds, the system will disarm automatically.
RFD OPERATOR MANUAL
2-8
2.3.6.
Disarm the Detonator Unit. Depress the “DISARM” switch, the Controller
Unit will transmit the Disarm command to selected Detonator Units. Selected Detonator
Units will internally discharge their firing capacitor. Selected Detonator Units that
receive the Disarm command will become Disarmed within 3 seconds of receiving the
command. The green DISARMED light for selected Detonator Units will begin to flash
on the Controller Unit display panel. The Controller Unit will then request status of
selected Detonator Units. If the Controller Unit is within range of the selected Detonator
Unit transmitter, the green DISARMED light for that Detonator Unit will turn to steady on
the Controller Unit display panel. If the Controller Unit is out of range of the selected
Detonator Unit transmitter, the green DISARMED light for that Detonator Unit will
continue to flash on the Controller Unit display panel. If the Fire command is not sent
within 60 seconds of Arming, the system will Disarm automatically.
CAUTION Do not assume the Disarm command has been received by the
Detonator Unit unless DISARMED status is confirmed with a steady DISARMED light
for that Detonator Unit on the Controller Unit display panel. If distance appears to be
the problem, move closer to the Detonator Unit following standard procedures for this
type of situation. The “STATUS” and/or “DISARM” switches may be pressed repeatedly
as the Detonator Unit is approached. Maintain a safe distance from the Detonator Unit.

blasting caps, or other explosives.
2.3.7.
Activate the Detonator Unit Firing Circuit. Depress the “FIRE” switch for
1/2 second and the Controller Unit will transmit the Fire command to selected Detonator
Units. If the “FIRE” switch is pressed during the firing capacitor charge time, the
Controller Unit will wait until the Detonator Units have had time to fully Arm, and then it
will send the Fire command automatically. The Controller Unit will only transmit the Fire
command to selected Detonator Units whose status is Armed. The selected Detonator
Units will be placed in Fire Mode and discharge the firing capacitor across the binding
posts. The red ARMED light will turn off and the green DISARMED light for each
selected Detonator Unit will begin to flash on the Controller Unit display panel. The
Controller Unit will then request status from the selected Detonator Units. If the
Controller Unit is within range of the selected Detonator Unit transmitter, the
DISARMED green light for that Detonator Unit will turn to steady on the Controller Unit
display panel. If the Controller Unit is out of range of the selected Detonator Unit
transmitter, the green DISARMED light for that Detonator Unit will continue to flash on
the Controller Unit display panel.
2.3.8.
Multistage Firing of Detonator Units. Multistage firing provides the ability
to Arm all eight Detonator Units at one time, and select any combination of the
Detonator Units to Fire at different intervals within the 60 second Arm period. The
procedure for multistage firing is :
•
Depress “1” though “8” switches.
