Application
The sounder can be used as a base to install
intelligent heat or smoke detectors to combine
detection and alarm. It can also be used as a sounder.
The audible control part of the sounder has two wires.
Used as the sounder, it needs separate wiring to
connect with detectors.

The sounder can be directly connected to I-9308
module, which occupies two consecutive address
points. When there is fire alarm message, it activates
low address to give pre-alarm sound, activates high
address to give fire alarm sound. System wiring is
shown in Fig. 3.
