Features
Electronically addressed. The address can be
modified in field.
Built-in microprocessor, processing information
intelligently.
Two working modes (Mode I, II) available.
Installed on detector base, easy for installation and
removal without additional wiring.
Description
I-9405 Addressable Sounder base is a base with an
integrated 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.

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
of 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 C on the sounder base
to mark A of the base, and rotate the sounder base
clockwise to B. 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.
Programming
The sounder base can be programmed using
DR-P910B programmer in field. Connect the
programmer with Terminal 1 and 3 of the sounder
base. When the sounder base occupies two
addresses, only the lower address (fire alarm sound)
needs to be programmed, and the higher address
(pre-alarm) will be automatically programmed by
adding 1 to the lower address. Refer to
P-9910B Hand
Held Programmer Installation and Operation Manual
for details.
