22 1X-X3 Operation Manual
Stopping or restarting extinguishing sounders
To stop the extinguishing sounders, press the Extinguishing Sounders On button.
An Extinguishing Sounders On LED indicates that the extinguishing sounders are
active (sounding). The LED indicates the tone of the extinguishing sounders:
flashing for an intermittent tone, steady for a continuous tone.
The extinguishing sounder tone depends on the extinguishing status
(extinguishing activation or extinguishing released) and the system configuration.
Normally, this tone is intermittent for activation and continuous for released.
Consult your system installer to determine whether these default settings are
used for your site.
Extinguishing sounders can only be stopped when the control panel is in
extinguishing released state (the Released LED is steady). To restart stopped
extinguishing sounders, press the Extinguishing Sounders On button again.
The control panel may provide additional extinguishing sounders in expansion
modules linked to the preactivation or released state which activate continuously.
These outputs accept the stop and restart commands normally.
