Description
DI-M9101 Intelligent Combination Heat Photoelectric Smoke
Detector integrates photoelectric detection and fixed temperature
detection technology by combining smoke sensor and
semi-conductor heat sensor in mechanism and circuitry structure.
Just because of the combination of smoke detection and heat
detection, it not only overcomes the disadvantage that detectors
using common infrared scattering technology are insensitive to
black smoke with small particles, but also can pick up fire with
obvious rise of temperature such as alcohol flame, thus extending
its application range.

Please install the base according to following steps:
1) 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.
2) 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.
3) 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.
There are four terminals with numbers on the base.

Recommended Cabling
1.0mm2or above fire cable is recommended, laid through metal or
flame-retardant conduit, but subject to local codes. Different color
cables for remote indicator are used to avoid wiring mistake.
It can connect with UL certificated intelligent control panel from our
company.
Installation
Refer to D Series Detector Application Bulletin for additional
installation instructions.
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 A on the detector with B on the base, rotate the
detector to align mark A with mark C (Refer to Fig. 1 and 2 for the
position of the marks), the detector will be fitted to the base.
Fig. 4 shows the installation of the detector.

Application
Fixed temperature and level 2 are default. The detector can be
addressed, read or written in field by using P-9910B programmer.
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 sensitivity or parameter and press Program, the
screen will show a “P”, the corresponding sensitivity or parameter is
programmed. Press Clear to clear the "P". Input locking password
and press Clear to return.

Read Sensitivity Level: in power-on state, pressing Test,the screen
displays address of the detector. Pressing “Up”,display sensitivity
level, device type and initial sensitivity in turns.
Testing
Before testing, please ensure that the detector has been
installed correctly and powered up. After 10 seconds, testing
begins.
Before testing, 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.
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:
1) Reed Switch Testing
Magnetic test zone is shown in Fig. 5. Put the magnet of
commission tool close to that of the detector and hold on for a few
seconds until the detector generates alarm.

Test Zone

2) Smoke entry test
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:
Manufacturer
Model
Trutest
AERO400
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.
3) Temperature rise test
Approach a heater (such as a hair drier of 1000w-1500w) to the
thermistor of the detector until it alarms. It is 12 inches between the
hair drier and the thermistor to avoid damaging on the plastic
enclosure of the detector
If a detector fails in testing, replace it. After testing, reset the
detector. Notify the proper authorities that the system is back to
normal operation.
Maintenance
Clean the detectors regularly, at least once a year to ensure
normal operation of the system.
If unwanted alarms are often found of the detector on site, the
sensing chamber should be cleaned. Power must be removed
from the detector before cleaning.
Steps for chamber cleaning:
a) Open the top cover of detector, and draw out the sensing
chamber by slightly lifting its two sides using a straight
screwdriver, as shown in Fig.6.
Fig. 6
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.
c) Put back the chamber and the top cover.
Cautions
1. Dust covers can’t be removed until the project is put into use
formally. Take well care of dust covers for future use.
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.
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.
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.
8. The smoke detector cannot last forever. In order to keep the
detector working in good condition, please maintain the equipment
continuously according to recommendations from manufacturers
and relative state standards.
9. The detectors must be tested regularly, at least once a year.
10.The base should be fastened and the wire should be connected
reliably.
11.Fire LED of the detector should face the main entrance where
people can watch it easily.
12.Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suitable for
that purpose.
