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
liable to occur with large amount of radiation and no
smoldering stage, or where quick response to a fire is
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
detection loop or in non-addressable mode connecting
to 24VDC power supply to transmit signal by
outputting different resistance values.
Connection and Wiring
Screened 2-core cable with cross section 1mm2or
above, and outer diameter φ8 mm is required for field
wiring. Please follow the steps below:
(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) Fasten the back cover with tools, and make sure
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) Please 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 cable at the “earth” mark.
The detection window shall face the protected
area.
Note: The detector shall be installed 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 supply 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 polls the detector status through the loop,
and displays its fault and fire alarm messages.

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. If the
resistance is 4.7kΩ, the detector is in normal standby
state; if the terminals are shorted, the detector is in fire
condition; if the terminals are open, the detector is in
fault condition.
The detector has 3 classifications. The factory default
is Class 1. The address and sensitivity can be read
and changed using P-9910B Programmer. Please
refer to P-9910B Hand Held Programmer Operation
Manual for details.

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

(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,
