1.1. PURPOSE

1.1.1.

1.1.2.

1.1.3.

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).

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 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 3mm non-electric shock tube running to the

explosive. The Mini Controller Unit communicates to the Remote Units through a two-

way RF transmitter data link, for a typical distance greater than Error! Reference

source not found. (8 km). The Remote Unit can typically return communication for a

distance greater than Error! Reference source not found. (1.6 km). Actual

communication range is dependant upon a variety of factors such as terrain, obstacles,

antenna height, and local interference.

Throughout this manual, the tem “Remote Unit” is a generic term that is used

for both the Electric Remote Unit and for the RSTI.

1.2.5.

The Mini Controller Unit 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 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 or if the relative humidity is above 90%. Towel

dry vents prior to opening. The vents should be OPEN, when stored in a dry hot

environment.

The Mini Controller Unit and Remote Unit (with vents closed) are airtight to an

altitude of 30,000 feet and watertight to a depth of 100 feet.

The Mini Controller Unit and Remote Unit is shock resistant, drop tested from

5 feet onto 3 inches of steel plate backed by concrete.

The battery pack and unit electronics are electrically isolated from the unit

case.

The Mini Controller Unit and Electric Remote Unit have a temperature

operation from -22 ºF to +140 ºF (-30 ºC to +60 ºC). The RSTI has a temperature
