Second Speaker Alarm Tones

The second speaker feature of the Nightingale PPM3 enhances the alarm tone
functionality by providing a completely independent backup to the monitor's main
speaker.
The way the second speaker works is very simple. Whenever the monitor starts
sounding an audible tone for an alarm condition, it starts a timer. If the alarm
tone is still sounding after a certain length of time (normally two minutes), the
second speaker will also start sounding. When you silence the alarm, both the
main speaker and the second speaker (if it was sounding) are silenced.
The amount of time delay between when the main speaker starts sounding and
when the second speaker starts sounding can be set anywhere between 0 to 180
seconds via the Setup Alarms menu (under the Setup Administration menu).
Since the second speaker has a slightly different sound than the main speaker, it
also serves to provide you with an indication of when a given alarm has been
sounding for longer than the pre-set delay time.
Other than starting the second speaker after the pre-set delay time, there is no
change to the way the monitor handles alarms, or to the way you need to respond
in order to silence or suspend the alarm tones.
