CLR Stops warning tones prior to completion of programmed time. Some tones "ramp down"
prior to turning off.
WAIL Siren tone. Initiates a slow rise, high-pitched tone for four seconds, followed by a softer,
winding-down for one second. This sound pattern continues for as long as the timing
duration is set.
ATK Siren tone for National Attack. Initiates a faster rise, high-pitched tone for one second,
followed by a winding down tone for one second. This sound pattern continues for as long
as the timing duration is set.
ALRT Siren tone for Alert. Initiates a quick rise then steady tone for as long as the timing
duration is set.
AIR HORN
Siren tone. Initiates a pulsing buzzing tone which blasts in intervals of 1.6 seconds for as
long as the timing duration is set.
HI-LO Siren tone. Initiates a highly pitched tone with a "Dee" sound for 0.8 seconds, followed by
a lower-pitched "Doo" sound for 0.8 seconds. This sound pattern continues for as long as
the timing duration is set.
WHP Siren tone for Whoop. Initiates a high-pitched, repetitive rise-only sound for three seconds,
