Photoelectric Smoke Detector
Fault self-diagnostic.
A magnet test available.
Providing for connections to remote indicators.
Built-in microprocessor stores 14 history data.
Polling LED can be set to OFF.
Standard: UL268.
DI-M9102 Intelligent Photoelectric Smoke Detector (the detector)
can form fire alarm system connecting with a fire alarm control panel
(FACP). The detector illuminates indicators to indicate fire condition
and transmits alarm signals to the FACP.
Using infrared scattering technology, with an innovative chamber,
the detector receives very weak infrared light under the normal
clean environment. If smoke particles enter the chamber, the
received light signal will be increased by scattering. When smoke
density reaches a certain amount, the detector will give alarm
signals. In order to reduce interference and power consumption, the
emitting circuit works in pulse mode to prolong the life of IR emitting
Connection and Cabling
The orientation base of DB-M01 is shown in Fig. 2.
Refer to D Series Detector Application Bulletin for additional
installation instructions.
Fix the base with two taping screws. Then align A (Fig. 1) on the
bottom of the detector to B (Fig. 2) of the base, and rotate the
detector clockwise to mark C. Mounting of the detector is shown in
Fig. 3.

Please install the base according to following steps:
Locate mounting holes on the rubber layer of the base
according to the holes on the back box, and punch the holes
with a screwdriver.
The polling LED is Normal by default, which can be modified to OFF
state using P-9910B programmer changes sensitivity of the
Count the number of cables needed and punch correct
quantity of holes with a screwdriver on the rubber layer.
Thread the cables through the cable entry holes.
Program sensitivity: In power-on state, input unlocking password
and press Clear to unlock. Press Function, then press “3”, the
screen shows “-” at the last digit. Input corresponding parameter of
the detector and press Program, the screen will show a “P”, the
parameter is programmed successfully. Press Clear to clear the "P".
Input locking password and press Clear to return.
Install the base onto the back box with screws.
Warning: Do not punch mounting holes and cable entry holes
bigger than needed. Do not punch more holes than needed.
Detectors Setup
Input Parameter of a Detector
Used together with UL certified GST-M200 control panel, loop of the
control panel should be connected with terminals “1” and “3” of the
base, polarity-insensitive; terminals “2” to anode of remote indicator
and “4” to the cathode. System connection is shown in Fig 3.
Read sensitivity: On power-on time, press Test, the LCD screen
shows the address of the detector; Press Up, it shows in turn the
sensitivity level, device type, initial sensitivity.

Before testing, please ensure that the detector has been
installed correctly and powered up. After 10 seconds, testing
can begin.
Before testing, 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.

Recommended Wiring
1.0mm 2 or above fire cable for all, laid out through metal conduit or
flame-resistant conduit, subject to local codes. The connection of
remote indicator should use different color cables to distinct polarity.
Status of Polling LED
All detectors must be tested after installation and periodically
thereafter. Testing methods must satisfy the Authority Having
Jurisdiction (AHJ). Detectors offer maximum performance when
tested and maintained in compliance with NFPA 72. The detector
can be tested in the following way:
Magnet test
Magnetic test zone is shown in Fig.5. Put the magnet of commission
tool close to the zone of the detector and hold on for a few seconds
Issue 1.05
until the detector generates alarm.
6. The detector may not warn you about fires caused by
insufficient safety measures, violent explosions, leaking gas,
improper storage of flammable materials like diluents and other
safety hazards, arson or children playing with fire.
Test zone
7. The alarm of a smoke detector used in high velocity
environment will be delayed due to dilution of smoke by frequent
and fast airflow.

Smoke test
8. Smoke detectors have their own service life. In order to keep
the detector working in good condition, please maintain them
according to recommendations from manufacturers and relative
state standards.
9. The detectors must be tested regularly, at least once a year.
The Trutest model 300 Aerosol Smoke Detector Tester can be used
for smoke entry testing. Set the generator to represent 4%/ft to 5%/ft
obscuration as described in the Trutest manual. Using the bowl
shaped applicator, apply aerosol until the panel alarms.
Additionally, canned aerosol simulated smoke (canned smoke agent)
may be used for smoke entry testing of the smoke detector.
Recommended aerosol smoke products are:
When used properly, the canned smoke agent will cause the smoke
detector to go into alarm. Refer to the manufacturer’s published
instructions for proper use of the canned smoke agent.
Warning: Canned aerosol simulated smoke (canned smoke agent)
formulas will vary by manufacturer. Misuse or overuse of these
products may have long term adverse effects on the smoke detector.
Consult the canned smoke agent manufacturer’s published
instructions for any further warnings or caution statements.
10. Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for
that purpose.

b) Use a vacuum cleaner or cleaned, compressed air to
remove dust and debris from the insect guard and the sensing
chamber. The sensing chamber can also be cleaned by clear
water and brush. Put the sensing chamber in clean water to
brush the dust inside and take out to dry it.

2. Dust covers effectively but not absolutely prevent dust particles
from going into detectors. So, we recommend that detectors
should be removed prior to construction, decoration, or other
activities producing dust. The proper authority should be informed
of detectors removing.
3. Be careful not to damage the detector in maintenance.
4. The smoke detector may not sense fire that where smoke
cannot reach it, such as in chimneys, in walls, on roofs, or on the
other side of closed doors.
5. The detector cannot monitor the place beyond protection area.
