The device can generate audible alarm signals after being connected to a 24 V DC
power supply. It can be used with a re alarm control panel through an output
module or interwork with an extinguishant control panel to form a gas re
extinguishing alarm system. If an incident occurs, the re alarm bell generates a
strong audible alarm signal once receiving the control signal to warn onsite
personnel.
