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.

or 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 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.

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.
