Description

DI-9101E Intelligent Combination Heat Photoelectric
Smoke Detector 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

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

1.0mm2 or 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.

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 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. 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, reset the detector. 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.
