1678 RFD OPERATION MANUAL 1
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 and non-electric
detonator devices. The System is strictly an electronic device, containing no
explosive. The Controller or Mini Controller Unit shall be operated from 100 feet (30
meters) to five miles (8 km) from the explosive. The Electric Remote Unit shall be
placed at the explosive site, with a two-conductor firing line running to the explosive.
The Remote Shock Tube Initiator (RSTI) is placed at the explosive site, with non-
electric shock tube running to the explosive. The Controller or Mini Controller Unit
communicates to the Remote Units through a two-way RF transmitter data link, for a
typical distance greater than 5 miles (8 km). The Remote Unit can typically return
communication for a distance greater than 1 mile (1.6 km). Actual communication
range is dependant upon a variety of factors such as terrain, obstacles, antenna
height, and local interference.
1.1.3. Throughout this manual, the term “Controller” is a generic term that is used
whenever applicable for both the Controller Unit and for the Mini Controller Unit.
1.1.4. Throughout this manual, the term “Remote Unit” is a generic term that is
used whenever applicable for both the Electric Remote Unit and for the RSTI.
1.2. ENVIRONMENTAL CONSIDERATIONS
1.2.1. The Controller and Remote 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, depth, or
temperature. This equalizes pressure within the case to the outside environment. DO
NOT open the vent if there is water on or near the vent or if the relative humidity is
above 90%. Towel dry vents prior to opening. The vents should be OPEN whenever
the unit is stored in a dry hot environment.
1.2.2. The Controller and Remote Units (with vents closed) are airtight to an
altitude of 30,000 feet (9,000 meters) and watertight to a depth of 100 feet (30
meters).
1.2.3. The Controller and Remote Units are shock resistant, drop tested from 5
feet onto 3 inches of steel plate backed by concrete.
