Using Site Selectable Alerts (ASTRO
25)†‡
A Site Selectable Alert (SSA) is an Intelligent Lighting indicator
together with audio alert sent to radios at a site or a few sites to
notify the users when there is a special situation that they need
to be aware of. Only authorized radios are enabled to send
SSA.
Upon the activation of a SSA, the receiving radios display the
alert alias and generate the periodic alert tone.
Note: Alert alias, alert tone, and alert period can be
preprogrammed. Alert period is the duration for the
radio to repeat the alert tone. An interval of 5 seconds
might impact the battery life of the radio. Check with
your dealer or system administrator for more details.
When mixing SSA with received voice audio, the SSA
alert is reduced in volume to ensure that the voice
message is still heard clearly. Therefore, it is important
that the SSA audio files are created with clear loud
audio to ensure they can still be heard clearly when
played at reduced levels.
