4.7 Listen-in Time
The Listen-in Time is the amount of time you can listen to sounds
from the Model 1108’s built-in microphone at its installation site.
When you call in for a Status Report, the Model 1108 announces
Listen-in Time at the end of its first round of status readings,
saying,“Listen to the sound level for (programmed time entered).”
The programmable range is from 0 to 255 seconds (or up to 4.17
minutes). The default value is 15 seconds.
NOTE
The microphone is also used to monitor high sound
level. See Chapter 5, Section 5.10 through Section
5.11.1.
