For audible devices such as bells and piezo mini-horns that may be silenced either manually
or automatically. While sounding, these follow the pattern appropriate for the condition: the
Silenceable Signal
configured evacuation code (default is temporal code) during single-stage alarm, or two stage
general alarm, or the alert code during a two stage system's alert (first) stage.
For audible devices such as bells and piezo mini-horns that may not be silenced either
manually or automatically. While sounding, these follow the pattern appropriate for the
Non-Silenceable
condition: the configured evacuation code (default is temporal code) during single-stage
Signal
alarm, or two-stage general alarm, or the alert code during a two stage system's alert (first)
stage.
Silenceable Visual For visual devices such as strobes that use no code pattern (they are continuous).
Non-Silenceable
Same as previous, but is non-silenceable.
