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.
