alarm.
If this sound level exists for 8 consecutive seconds (default) or
for the programmed length of time, the OMA-P1104 will dial
out with an alarm message.
NOTE
The proximity of the audible alarm to the
microphone is extremely important.
Normally, the OMA-P1104 and the audible
alarm must be in the same room. The maximum
distance can vary considerably depending on the
alarm, the acoustics, and the size of the room.
During an alarm dial-out, the microphone allows four-second
intervals to listen-in to sounds at the OMA-P1104’s location.
When calling for a Status Report, the microphone permits
listening to on-site sounds for a programmed time interval.
