1. INTRODUCTION
1.1. THEORY OF OPERATION
1.1.1. The Remote Firing Device (RFD) is used to activate both electric and non-
electric detonator devices. The system is strictly an electronic device, containing no
explosive. The Remote Unit is placed at the explosive site, with a shock tube or the
electric detonator firing cable running to the detonator(s). The Controller is placed at
the intended firing position.
1.1.2. Using remote control technology allows the blaster to increase his standoff
distance for maximum safety. With the blaster unconnected to the firing line, he is free
to move around to achieve both the safest firing position, as well as the preferred
viewing position. Blast efficiency is improved as the consumption of non-electric leadin-line is reduced by as much as 90%. In subsurface operations, safety is achieved
when all headings are fired from one position with all personnel above ground.
Significant cost savings may be found in comparison to expensive mains firing systems.
1.1.3. Critical features of this Remote Firing Device over other systems are the two-
way communication link and the timed automatic-disarming function. The two-way
communication feature provides a high degree of safety, by allowing the blaster to verify
that each Remote Unit is disarmed before approach. The automatic-disarming function
ensures that the unit returns to a safe state in the event of a loss of communications,
after a time out period.
1.1.4. In subsurface operations, safety is achieved when all headings are fired from
one position with all personnel above ground. Significant cost savings may be found in
comparison to expensive mains firing systems. The motion detection feature can be
used to help determine if the blast has been initiated successfully.
1.2. STORAGE AND ENVIRONMENTAL CONDITIONS
1.2.1. The Controller Unit and the Remote Unit cases (with lids closed) are airtight,
watertight, and dustproof. The Remote Unit should normally be operated with the lid
closed and fastened. The internal case contains the circuit electronics and should
remain sealed.
1.2.2. The Controller and the Remote Units are shock resistant and will handle
considerable abuse. They have been drop tested from 6 feet (1.8 m) onto concrete.
1.2.3. The Remote Unit firing terminals are electrically isolated from the firing energy
at all times except when firing.
1.2.4. The RFD system should be stored in a cool, dry place. The storage
temperature range is -4 to 86 F (–20 to 30 C). Exceeding the storage temperature
range may result in damage to the internal battery packs.

2.1.1. Figure 2-1 shows the Controller Unit. The Controller Unit is responsible for
initiation of all communications with the Remote Unit(s). The Controller Unit’s case is
yellow for easy identification.
2.1.2. The Controller has an electronic key that must be installed before Arming and
Firing is allowed.
1673 OPERATION MANUAL REV A
4
2.1.3. The Controller Unit is capable of commanding up to 64 Remote Units, in 8-
Remote groups that are hereafter referred to as “Systems”.
2.1.4. The Controller can operate in standby for typically 12-16 hours before
recharging is required. The Controller’s charger is internal and is capable of worldwide
operation. Typical charge time is 3 hours. The battery system features test and
discharge functions.
2.1.5. The Controller features an internal history event log which stores 1024 events
in non-volatile memory. The history log can be used to obtain information on the
operation and performance of the RFD. Each event is logged with the current date and
time along with GPS coordinates (if available).
2.1.6. When the Electric Detonator circuit has been selected on the Controller,
transmission signal levels from responding Remote Units are automatically reduced for
safety around blasting caps. The Controller’s transmission signal level remains
unchanged.
1673 OPERATION MANUAL REV A

2.2. REMOTE UNIT
Figure 2-2 Remote Unit
2.2.1. Figure 2-2 shows the Remote Unit. The Remote Unit contains the fire circuits
used for the initiation of detonators. The Remote Unit is normally positioned at a
protected location relatively close to the blast area.
2.2.2. The electronic keys used in the Remote Unit are matched to the Controller
and must be installed for communication, arming and firing.
2.2.3. The Remote Unit’s electric detonator circuit develops a minimum of 350V DC
@ 5J with 27Ω of internal impedance. The maximum recommended series firing
resistance (firing cable plus detonators) is 150Ω for group 1A detonators. Consult the
specifications for the specific detonator that you are using.
1673 OPERATION MANUAL REV A
6
2.2.4. The Remote Unit’s shock tube circuit develops a high voltage spark to initiate
non-electric shock tube.
2.2.5. The Remote Unit can run on standby for typically 12-16 hours before
recharging is required. The Remote Unit’s charger is internal and is capable of
worldwide operation. Typical charge time is 3 hours. The battery system features test
and discharge functions.
2.2.6. The Remote Unit features an internal history event log which stores 1024
events in non-volatile memory. The history log can be used to obtain information on the
operation and performance of the RFD. Each event is logged with the current date and
time along with GPS coordinates (if available).
2.3. BATTERY CHARGERS
2.3.1. Both Controller and Remote Units use internal battery chargers which are
powered by +12VDC from an external AC adapter. The AC adapter operates from 100–
240VAC, 50-60 Hz, and has changeable pins for worldwide operation. Typical charge
time is 3 hours. Charging should be conducted indoors. Do not attempt to substitute
another power supply or equipment damage may occur.
2.3.2. For battery charging procedure, refer to Section 3.2.
2.4. ENABLE KEYS
2.4.1. Each system is supplied with a unique group of enable keys. The enable
keys contain the encoded information required for operation.
2.4.2. The Controller Unit has a unique enable key, and will only arm and fire with
this specific key installed. The Controller Unit will perform status and disarm functions
without the key installed. The Controller Unit automatically disarms all Remote Units
upon key removal. The Controller key is labeled with a ‘C’ to distinguish it from the
Remote keys.
2.4.3. The Remote Units’ use of the enable key can be configured for one of two
operation modes.
2.4.3.1. In generic (default) mode, the Remote unit assumes its System and Unit
numbers from the key installed. Any key can work in any Remote unit (as long as that
Remote is on the correct frequency assignment). Generic mode allows the flexibility to
move Remote Units within different systems and units within those systems by changing
the keys.
2.4.3.2. In dedicated mode, The Remote Unit is setup to only work with one specific
key; for example a Remote Unit setup in dedicated to be Remote #3 from System #8
can only work with a key that matches these values. Dedicated mode can help when a
very strict key control plan is required.
