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 lead-
in-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.
![](/img.php?id=2185220&img=bgd.png)
1673 OPERATION MANUAL REV A

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.

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.

2.7.6. SYSTEM SELECTED: This is the active System # that is currently selected.
You can change to select a different System # on the Normal menu by choosing option
‘2’ and entering the number of your desired System (1-8). The Controller is capable of
commanding up to 8 Systems, but it can only command one system at a time. Each
System contains up to 8 Remote Units, for a total operational capability of 64 Remote
Units.
2.7.7. CURRENT BATTERY VOLTAGE: This represents the current state of charge
of the unit. It is recommended that the unit be recharged when the battery falls below
7.5V. The unit will operate normally down to 7.0V however below this the unit must be
recharged. If you are operating this system at a temperature below freezing, it is
recommended that you fully charge before use. The batteries will start to lose capacity
below 0 ºC (32 ºF). A more thorough battery test can be performed by pressing the
BATT TEST switch. Below 7.0 V the yellow POWER light begin flashing.
2.7.8. KEY PRESENT: This indicates that the Electronic Key is installed is the
correct key for your Controller. The Controller can only be matched to one key at a time.
An error will be indicated if a different key or if a faulty key is installed. The yellow KEY
light in the SYSTEM indicators also lights solid when the correct key is installed, but will
blink if an incorrect key is installed. The Controller’s key must be present to allow
arming and firing. Other operations such as status and disarm may be performed
without the Controller’s key installed.
The Controller’s key should be stored in a secure place away from the Controller when
you are not actively engaged in blasting activities. Without the Controller’s key, the
Controller is incapable of arming or firing the Remote Units.
Note: Removing the Controller’s key will cause it to select and send a disarm command
to all Remote units of the currently selected system. Avoid removing the Controller’s key
when the Controller is on, unless you intend to disarm all Remotes. Normally this would
be in a panic situation.
2.7.9. FIRING MODE (FM): ST indicates the Shock Tube Initiator circuit is selected.
ED indicates the Electric Detonator circuit is selected. When arming and firing, the
current selection will be used. The Controller remembers the last mode selected the
next time you turn it on. You can change the Firing Mode selection on the Normal menu.

The firing capacitor is not charged while the unit is armed, but as the unit is in the act of firing. After
firing, the capacitor voltage will be briefly reported as the unit disarms back to the READY state.
2.11. SHOCK TUBE FIRING TIP
2.11.1. Shock Tube Initiation. The shock tube initiator circuit ignites the explosive powder
contained inside of the shock tube creating a dust explosion which transverses through tube at a
high rate of speed toward to the detonator. The Remote Unit develops a high-energy spark at the
igniter needle located in the Igniter Port shown in Figure 2-13 of the firing tip. Care must be taken
to ensure no water or moisture is allowed on or near the igniter needle, or misfires may occur.
Keep the tip clean and dry before use and keep the shock tube ends capped at all times. Once the
shock tube is installed onto the igniter needle, the unit may be operated in the rain.
Figure 2-13 Firing Tip, Shock Tube
2.11.2. Shock Tube Installation on Firing Tip. Figure 2-13 shows the shock tube firing tip and
how the shock tube is installed.
1. Make a fresh cut with a sharp knife removing the last 6 inches of shock tube.
2. Insert the shock tube through the guide hole on the tip as shown in Figure 2-13. The guide
hole secures the tube to the tip and prevents pulling out.
1673 OPERATION MANUAL REV A
23
3. Insert the tube into the igniter port on the side. Slide the tube into the igniter port until the
tube comes to a firm stop.
4. Pull the tube exiting the guide hole, removing any slack in the loop formed. This prevents
the tube from coming loose from the igniter needle. Do not allow the tube to form a kink.
2.11.3. Tip Care. The two tips provided with the RFD are rugged, and will each last for up to
500 shots if properly cared for. Take care to keep mud and debris from getting on the igniter
needle. In some cases, the tip’s life can be extended by washing in soapy water and gently
rubbing the igniter needle with a non-metallic device such as a cotton swab.
2.11.4. Tip Replacement. It is recommended the tip be replaced at regular intervals to prevent
the likelihood of misfires resulting from worn tip electrodes. You may choose to hold one tip in
reserve as a replacement or spare at a location apart from your RFD. Then estimate your tip
usage, and schedule replacement when the tip’s use reaches your estimated 500 shots.

5.8. PROGRAMMING ELECTRONIC KEYS
5.8.1. The Key Programming Mode of the Controller allows you to create replacement keys if
you have a lost or damaged key, or you can create a new key if you need to add a new Remote to
your system. An important feature of the key programming mode is that it will not allow duplicate
keys to be created. This means that if a key is lost or stolen, once you reprogram the keys, the key
that was lost or stolen will no longer be functional, unless it also is reprogrammed.
5.8.2. When programming a key associated with a particular system, you must also reprogram
all of the other keys associated with that system at the same time (up to 8 Remotes and the
Controller key must be programmed together). You do not need to reprogram keys that are
associated with other systems, unless you are adding or replacing their keys as well.
5.8.2.1. Identify which systems (1-8) the new or replacement keys will be matched to. If you have
8 Remotes or less, by default you will be reprogramming only the System #1 keys. If you have
more than 8 Remotes, you may be programming keys from other Systems as well.
5.8.2.2. Gather all of the keys associated with the system(s) for which you have identified in
5.8.2.1 to the Controller Unit. You must reprogram all Remote Units from that system together at
the same time; even the ones that are working correctly.
5.8.2.3. Remove the Controller’s key from the electronic key port. Turn the Controller on, and
press the MENU switch to enter the start menu.
5.8.2.4. Press ‘2’ to select the Advanced Menu. Enter the PIN supplied to you by the

Figure 6-1 1673 RFD Configuration – Main Screen
6.3. READING THE EVENT HISTORY LOG
6.3.1. Within both the Controller and Remote Units is stored a record of the last 1024 operation
events. Recorded events include commands (arm, fire, disarm, status), battery status, key status,
firing voltage, motion detect level, auto-disarm, internal temperature, and selected firing circuit. The
Controller and Remote’s event history logs differ; the Controller log contains operation information
for the system that was selected when the event was recorded. The Remote’s history log contains
only information pertaining to its own operation.
6.3.2. To read the event history log, turn the Controller or Remote on, and press the MENU
switch to go to the Start menu display. Select ‘2. Advanced User’. The screen will prompt you for
the Advanced User PIN. Enter the Advanced User PIN provided for your system including all 5
digits (include leading zeros too).

8. MAINTENANCE
8.1. MAINTENANCE PROCEDURES
8.1.1. Normal Maintenance. Normal maintenance is limited to periodic battery charging and
cleaning the outer surfaces and panels with a damp cloth removing dirt and debris. Ensure the
CHARGE/PROGRAM, ELECTRONIC KEY port, and firing terminals are clean and dry with a
cotton swab. Check for signs of corrosion around and on connector pins. Ensure the electric
detonator firing terminals are clean, and easy to depress.
8.1.2. Scheduled Maintenance. It is recommended that the 1673 RFD be returned to the
manufacturer or an authorized service shop every two years for periodic maintenance. At this time
the latest improvements are added, fresh battery packs are installed, the radio transceivers are
tuned and verified, and the overall performance of the RFD is thoroughly tested.
8.1.3. Corrective Maintenance. Corrective maintenance should be performed at the
manufacturer or an authorized service shop only. Replacement of parts or repair at the user level
and field disassembly is strongly discouraged and may result in death, injury, or unsafe equipment
operation. The Remote Unit contains dangerously high voltage levels when armed.
8.1.4. Battery Maintenance. Your RFD contains heavy-duty 7.2V NiMH battery packs that
should be replaced after 500 charge/discharge cycles or every three years, whichever comes first.
If a decrease in run time has developed, there may be a memory problem caused by repeated
shallow discharges or interrupted charge cycles.
8.1.5. Battery Condition (Discharge). To keep the battery packs running optimally, it is
recommended that you perform a full discharge before recharge using the discharge feature of the
at least once per month. To perform a Battery Condition, connect the Charger Power Supply to a
wall outlet, and connect the cable connector to the CHARGE/PROGRAM connector. Turn the unit
on and then press and hold the ‘BATT TEST’ switch for 5 seconds. The unit will discharge the
battery to a low level and then it will be recharged. The whole process takes up to 10 hours to
complete. Always ensure the power supply is connected and working before discharging.
Figure 8-1 Battery Condition (Discharge Battery)
1673 OPERATION MANUAL REV A
54
8.1.6. Tip Care. The two shock tube igniter tips provided with the RFD are rugged, and will
last for 500 or more shots if properly cared for. Take care to keep mud and debris from getting on
the igniter needle. In some cases, the tip’s life can be extended by washing in soapy water and
gently rubbing the igniter needle with a non-metallic device such as a cotton swab.
8.1.7. Tip Replacement. As the tips are used, the electrodes will wear and eventually become
unreliable. Therefore, it is highly recommended that your company adopt a strict tip
replacement/tracking plan. Tip usage can be tracked using the serial number engraved on the tip.
Discard each tip when its usage reaches 500 shots. Always hold a replacement tip handy. You
may also dry fire the old tip and compare it to the sound and spark intensity of a new tip. If the old
tip’s spark is noticeably weaker, replace it.
