DESCRIPTION

The EQ2200UV Ultraviolet (UV) Flame Detector is
designed for use as part of the Eagle Quantum sys-
tem. The detector is equipped with both automatic
and manual optical integrity (
programmable options include sensitivity, time delay
and arc rejection. Operating status is indicated by
LEDs that are visible through the detector's viewing
window.

OUTPUT

The output of the detector is a status message that is
sent along the communication loop to the gateway
and logic controller in the Local Control Unit (LCU).
The UV detector supports ANSI/NFPA 72 Class A,
Style 7 communication with the LCU. System
response to the message is determined at the time of
configuration.

SOFTWARE SELECTABLE OPTIONS

The following options are software selectable through
a PC running Det-Tronics configuration software:
Two Operating Modes
The operating mode determines the type of logic that
the UV flame detector will use for processing fire sig-
nals (either standard or arc rejection).
Arc Rejection (Factory Recommended) — The arc
rejection mode enables the detector to prevent nui-
sance fire alarms caused by UV from short-duration

SPECIFICATION DATA
UV Flame Detector
electrical arcs or electrostatic discharge, while main-
taining the ability to reliably detect the UV given off by
a flame. Typical applications that benefit from arc
rejection logic include electrostatic coating processes
and uncontrolled environments where transient UV
sources can be present, such as many typical out-
door applications.
Standard — In the standard processing mode, the
detector output (measured in counts per second) is
compared to the fire threshold (the "sensitivity" setting
as described below). If the radiant energy level from
the fire exceeds the selected alarm threshold level,
the time delay begins (if a time delay is selected). If
the radiant energy level from the fire remains above
the selected sensitivity level for the duration of the
time delay, a fire alarm output is generated.
Standard signal processing is recommended for con-
trolled indoor applications only.
