RFD OPERATOR MANUAL
1-1
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 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.
1.3.3.
The Controller Unit and Detonator Units are shock resistant, drop tested from
5 feet onto concrete.
1.3.4.
The battery pack and unit electronics are electrically isolated from the unit
case.
