GST C-9104 User Manual
30301313 Issue 2.05
Features
Using excellent UV sensor.
High sensitivity, reliable performance, dust-proof,
damp-proof and corrosion-proof.
Description
C-9104 Conventional Ultraviolet Flame Detector
detects fire by analyzing ultraviolet radiation of
material flaming. It's applicable to places where open
fire, fire with intense flame radiation and fire without
smoldering stage take place easily, as well as places
where quick response to a fire is required. Used
together with other detectors, it can sense fire in time
to minimize losses as much as possible.
The detector is DC powered, which powers signal
processing circuit after voltage stabilization, the UV
sensor needs 300V voltage or so, which is provided
after boosted by transformer. When there is ultraviolet
light on the sensor, it discharges due to photoelectric
effect, and the strength of discharge is in proportion
with the intensity of UV light. Signal processing circuit
analyzes and processes its output signal, then
compares with alarm threshold and outputs alarm
signals. The alarming mode of the detector is current
output; it's shorted by internal 680 after alarming.
Connection & Cabling
Fig. 1 shows the structure of the detector and Fig. 2
the base (unit: mm).
Fig. 1
Thread the cable through the conduit of back box and
base; fix the base on the back box. There are four
terminals with numbers on the base. "1" and "3" to
power supply, "1" is anode and "3" is cathode, "2" to
next detector.
A fixed installation direction is ensured by the location
elements on the detector and the base. Fix the base
with two tapping screws, and then align mark C on the
detector with A on the base, rotate the detector to
align mark C with mark B (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the
base.

Installation
Warning: Before installation, please disconnect
power from the loop and verify that all the bases
are securely installed and wiring is correct at each
base.
Power up after all the detectors are installed.
Check the enclosure and labels before installation,
ensuring there is not nicks and distortion.
Fig. 3 shows the mounting of the detector.

Maintenance
The detector should be installed just before
commission and kept well before installation.
Corresponding measures should be taken for
dust-proof, damp-proof and corrosion-proof. Clean the
detector and do fire alarm tests regularly. Repair the
fault in time.
Cautions
The detector should be handled with care wherever it
is moved, avoiding collision, squeezing, and friction.
The detector is not suitable for the following places.
Where flameless fires are expected.
Where thick smoke spreads before flames.
Places where the "view" of the detector is easy to
be obscured.
Where the sun can directly or indirectly shine the
detector.
Where there are strong ultraviolet light source,
such as halogen and tungsten.
Where there is open flame, welding operation, X
rays and arc and spark etc.
