Description
I-9102 Intelligent Photoelectric Smoke Detector is an
addressable fire alarm device cooperating with GST
intelligent fire alarm control panels to build a fire
detection system. It shows fire alarm by LED
indicators and transmits the fire signal to the control
panel. Using infrared scattering technology, the smoke
density can be detected. The detector receives very
weak infrared light under normal smokeless condition.
If smoke particles enter the chamber, the received light
signal will increase by scattering. When smoke density
reaches a pre-set level, the detector will alarm out. In
order to reduce interference and power consumption,
the emitting circuit works in pulse mode to prolong the
life of IR LED.
Connection and Cabling

There are four terminals with numbers on the base.
1&3: Loop connection (polarity-insensitive)
2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Cabling
2
1.0mm or above fire cable is recommended but
subject to local codes.
Installation
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.
Note: The detector shall be horizontally installed. If
it has to be installed on an inclined plane, the
inclination angle shall not be over 45º.

Application
The detector is suitable for restaurants, hotels, office
buildings, school buildings, banks, warehouses,
libraries, computer rooms, power plants, etc.
The detector can be addressed in field by using
P-9910B programmer. Please refer to P-9910B Hand
Held Programmer Installation and Operation Manual
for details.
Maintenance
1 The detector should be installed just before
commission and kept well before installation,
taken corresponding measures for dust-proof,
damp-proof and corrosion-proof.
2 The dust-proof cover should not be removed until
the project plunged into usage. Otherwise it may
not report alarm properly.
3 Clean the detectors regularly, at least once a year
to ensure normal operation of the system.
4 Maintenance should be carried out for false alarm
detectors, either clean or replace the chamber if
necessary. Before cleaning, notify the proper
authorities that the system is under maintenance
and will temporarily be out of service. Disable the
automatic controls relating to the zone or system
under maintenance to avoid unwanted actions.
Steps for chamber cleaning:
a) Open the top cover of detector.
b) Draw out the chamber slightly shaking by
hand.
c) Clean the internal of the chamber by
alcohol cotton or other clean liquid swab
with tweezers. Make sure not to leave any
