Checking one's installation for hard-to-predict situations includes spotchecking for:
• Live audio. Coordinate the testing of audio with fire alarm and security alarm testing.
Using View, connect to that Multi-Media unit and check audio for feedback and
interference, before and during alarms.
Caution Loud alarms can interfere with microphones or a speaker at times when
they could be needed most.
• Recorded audio. After a day or two, check for background noise in recordings, using
a retrieval session to spotcheck each microphone for a few seconds at every half-hour
or so, during a 24-hour period. This can reveal if microphones are placed too near
sources of background noise (such as a vent) that are amplified to a point where they
interfere with audio. Hard to predict noise from the area—rush-hour traffic, passing
trains and planes, crowds in a stadium, and so on—may not have been apparent
during the installation of the microphones and speakers.
