SYSTEM APPLICATION
The Det-Tronics model R7404 Controller and C7050
Detector provide fast, reliable flame detection in a wide
variety of applications. The microprocessor based con-
troller simultaneously monitors up to 16 C7050 ultraviolet
(UV) detectors in up to 8 different zones. The system
uses the Automatic Optical Integrity (o
i
) feature, which
provides a continuous check of detector optical sur-
faces, detector sensitivity, and electronic circuitry of the
detector/controller system. Also included is automatic
fault identification, which monitors the system for proper
operation, and provides a digital display of system sta-
tus using a numerical code. Other features include indi-
vidual zone identification and “voting” capability, as well
as manual o
i
testing.
The C7050 Detector responds instantly to the ultraviolet
radiation that is emitted by a flame. It is designed for
use in hazardous locations and is particularly suitable for
use in outdoor applications because it is not affected by
wind or rain, and is insensitive to solar radiation. In addi-
tion, the detector does not respond to normal artificial
light.
Typical applications for Det-Tronics UV detection sys-
tems are:
Wherever highly combustible materials are involved
Where there is a need for instantaneous response to
flame
Wherever unsupervised areas require automated fire
protection
Where there is a large capital investment to be pro-
tected.
Examples of actual installations using the Det-Tronics UV
detector in automated fire protection systems include:
Petroleum Products
Gasoline transport loading terminals
Offshore drilling and production platforms
Pipeline pumping stations
Tank farms
Refineries
Marine engine rooms
Jet engine test cells
Gaseous Fuels
Butane and propane loading and storage
Pipeline compressor stations
Gas gathering facilities
Pipelines in highly populated areas
LNG loading, transfer and storage facilities
Hydrogen and ammonia production and refinery
reformers
Gas turbines
