Description
DI-9104Exd is a light-sensitive detector that detects
fire by picking up the ultraviolet light from flaming
material. It’s designed for areas where an open fire is
li able to occ ur with la rge amou nt of radiation and no
smoldering st ag e, or w her e q u i c k r es po n s e t o a f ir e i s
required. This detector can be applicable to zone 1
and 2 of explosive hazardous areas.
The detector is able to work either in addressable
mode connecting with GST intelligent fire alarm
control panel(FACP) to transmit signal through
detecti on loop or in non-addressable mode connecting
to 24VDC power supply to transmit signal by
outputting di f ferent resistan ce values.

Connection and Wiring
Screened 2-core cable with cross section 1mm2 or
abo ve, an d outer diameter φ8 mm is required for field
wir ing. Please foll ow the steps bel ow:
(1) Rotate down the back cover and the pressing nut.
(2) Thread a proper length of the cable through the
pressing nut, metal washer and joint washer in
sequence.
(3) Peal away the outer layer of the cable with 5mm of
metal core exposed, rotate in the cable together
with the joint washer, metal washer and the nut into
the detector housing, and fasten the nut using a
spanner.
(4) Connect the cables to corresponding terminals of
the detector, and the screen layer to the safety
earth position inside the housing.
(5) Fast en the back cover with tools, and make sur e
the detector is earthed through its safety earth
position on the cover.
Installation
(1) Fig. 1 is the schematic diagram for installing the
detector.
(2) Pl ease check the following after installation:
There shall not be any crack or air bubbles.
The back cover and the detector shall be
securely fastened.
There shall not be any scratch or crack on the
detecting window.
There shall be joint washer in the wiring hole.
The joint washer matches with the cable
diameter.
The pressing nut is locked.
There is earth cab le at th e “ earth” mark .
The det ecti on win dow shal l face t he pro tected
area.
Note: The d etector shall be in stalled in compliance
with relative installation codes. Make sure the
housing is in good condition.

Operation
The detector powered by 24VDC voltage, which may
come from control panel in addressable working mode
or 24VDC power suppl y in non-addressable working
mode.
In addressable mode, Terminal Z1 and Z2 are to be
connected with the loop of FACP polarity-insensitively.
The FACP p olls the detector status through the loop,
and displays its fau l t and fire alarm mes sages.

In non-addressable mode, 24VDC power supply can
be directly applied to Terminal Z1 and Z2. K1 and K2
output different resistance in different conditions. I f the
resistance is 4.7kΩ, t he det ector is in no rmal s tandb y
state; if the terminals are shorted, the detector is in fire
condition; if the terminals are open, the detector is in
fault condition.

Accessories and Tools
Maintenance
(1) The detector shall be cleaned at least once a year
to ensure normal operation of the system.
(2) Before cleaning, notify the proper authorities that
the system is undergoing maintenance and will
temporarily be out of service. Disable the zone or
system undergoing maintenance to avoid
unwanted alarms.
(3) The detector shall be tested after being cleaned
and re-installed. After testing, notify the proper
authorities the system is back in operation.
Caution
(1) The detector should be handled with care during
storage, transportation, installation, commission
and maintenance to avoid damage from falling,
im pact, ou t side f orce an d f riction.
(2) Instal lation and maintenance should strictly comply
with relative codes for explosive and hazardous
areas.
(3) Never open the cover for maintenance in field.
(4) The enclosure must be earthed.
(5) The len only endures low impact energy, so the
detector shall be installed the position wher e the
foreign objects can’t attack it.
(6) The following places are not suitable for the
detector:
Where flameless fire is to be exp ected.
Where intensive smok e spread s before flames.
Where the "view" of the det ector is opt to be
obscured.
Where the sun can directly shine or i ndir ectly
shine the d etecti on window.
Wher e ther e is st rong UV lig ht so urce in fiel d,
like a tungsten halogen lamp.
Where open fire, welding, X rays, arc or sparks
may exist in normal condition.
