Description
DI-9101 Digital Intelligent Multi Sensor designed
according to UL 268/UL 521, integrates photoelectric
detection and fixed temperature and rate of rise
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.
Connection and Cabling

2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Cabling
1.0mm2or above fire cable is recommended, laid
through metal or flame-retardant conduit, but subject to
local codes.
Note: Different color cables are used to avoid wiring
mistake.
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 A on the
detector with B on the base, rotate the detector to align
mark Awith mark C (Refer to Fig. 1 and 2 for the position
of the marks), the detector will be fitted to the base.
Fig. 3 shows the installation of the detector.

Application
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.
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.
Rate of rise and level 1 is defaulted.

Testing
Before testing, please ensure that the detector has
been installed correctly and powered up. After 10
seconds, testing begins.
1) The detector must be tested after installation and
periodical maintenance.
2) Testing method
a) Reed Switch Testing
Magnetic test zone is shown in Fig. 4. 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

b) Smoke test
Taking a smoldering cotton rope close to the
detector, blow the smoke into the detector until the
detector generates alarm.
c) Temperature test
Approach a heater (such as a hair drier) to the
thermistor of the detector until it alarms.
3) After testing, disconnect the power to the detector for
over 5 seconds to reset it. Notify the proper authorities
that the system is back to normal operation.
If a detector fails in testing, clean it by the steps in
Maintenance, and retest it. If it still fails, return it for
repair.
Maintenance
The detector should be installed just before
commissioning and kept well before installation,
taken corresponding measures for dust-proof,
damp-proof and corrosion-proof.
The dust-proof cover should not be removed until
the project is plunged into usage. Otherwise it may
not report alarm properly.
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. 5.
Fig. 5
b) Clean the internal of the chamber by alcohol
cotton swab with tweezers or using clean water
and brush. Make sure not to leave any fiber in
the chamber.
c) Put back the chamber and the top cover.
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.
The detector should be tested after re-installed to
ensure normal operation.
Fire simulation test should be done to the detector
at least every 6 months.
