4. PERFORMANCE
4.1. GENERAL ALARM
The General Alarm tone in the MPA 1600 system consists of seven short followed by one long tone
burst. Each short tone has approximately 1 sec. duration, each pause between tones approximately 1
sec. and the long tone has 7 sec. duration. The alarm signal sequence is continuously repeated. The
alarm tone is basically generated of a 1000 Hz sinusoidal tone.
The General alarm tone can be adjusted by means of loading different configuration data. Frequencies
between 200 and 2500 Hz can be selected along with triangular or sinusoidal curve form.
The configuration changes require a special administrative tool and are unavailable during normal
operation.
4.2. FEEDBACK COUNTERMEASURES
In the MPA 1600 system there are three different countermeasures available in order to avoid audible
feedback and disturbance during announcements.
− The MPA 1601 and 1604, Control Units are equipped with either a gooseneck or handheld
microphone with close-talk characteristics with excellent background noise suppression capability.
− The MPA 1601 and 1604, Control Units, are equipped with relays for disconnecting loudspeakers
in the close proximity when activated.
− Each audio interface can be programmed to be of a recording type. The message is temporarily
recorded and is automatically played back when the announcement is terminated.
