GST DI-9405 Quick Start Manual

Features
 With "sandwich" structure, it is easy to be installed
between DB-01 base and a detector.
 Three working modes settable (Mode I, II, III, and
the latter two available with pre-alarm state).
 16 tones of sound.
 Electronically addressed. The address and tones
can be modified in field.
Tone 14 and 16 are certified by EN 54-3:2014 and EN
54-3:2001.
Description
DI-9405 Addressable Sounder Base is integrated with
a buzzer. When there is a confirmed fire, it will give
audible alarm signal to warn people in field.
With a built-in microprocessor, the sounder base can
communicate with fire alarm control panel (FACP). On
receiving a start command from the FACP, the
microprocessor will control the buzzer to generate
pre-alarm or fire alarm sound according to the pre-set
working mode.
Wiring and Connection
Terminals of the sounder base are shown in Fig. 1.

1.0mm or above fire cable, subject to local codes.
Installation
Warning: Before installing the sounder base,
disconnect the power from the loop and verify that
all the bases are securely fixed and that the wiring
is correct on each base.
1 Before installation, make sure the enclosure is
free from scratch or distortion, and labels are
complete.
2 Mounting of the sounder base is shown in Fig. 2.
3 Secure the sounder base to detector base (Fig. 4)
with 2 tapping screws, and wire them properly.
Align the orientation mark B on the sounder base
to mark C of the base, and rotate the sounder
base clockwise to D. Refer to Fig. 3 and 4.
4 If the sounder base comes with a cover, align the
orientation mark on the cover to mark A of the
sounder base (Fig. 1), and rotate the cover
clockwise to B. If it's used as detector base,
remove the cover and install the detector on it with
the same method.

Application
The sounder base can be used as the base of
intelligent heat and smoke detectors to combine
detection and alarm in a single device. It can be
connected to the loop of FACP without additional
power supply.
Working Mode Setup and Tone Selection:
The sounder base has three working modes. The
factory default is tone 14, mode I.
The sounder base has 16 tones, the setup of which
also decides the setup of working modes.
➢ If the sounder base is set with one of the tones from
No. 1 to 16, it works in Mode I.
➢ If it is set with one of the tones from No. 17 to 32, it
works in Mode II.
➢ If it is set with one of the tones from No. 33 to 48, it
works in Mode III.
➢ Tone 1~16, 17~32 and tone 33~48 are completely
the same by one-to-one correspondence, with the
only difference that they work in different modes.
Please refer to the table of tones.
