Circuit Type Description
Silenceable Signal
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
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.
Non-Silenceable
Signal
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
condition: the 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.
Silenceable Visual For visual devices such as strobes that use no code pattern (they are continuous).
Non-Silenceable
Visual
Same as previous, but is non-silenceable.
Continuous On 100% of the time
Temporal Code 3 of 0.5 second on, 0.5 second off then, 1.5 second pause
March Code 0.5 second on, 0.5 second off
California Code 5 seconds on, 10 seconds off
