6.1.3 Tilt Angle for Alarm
The value of this parameter sets the angle at which the unit will enter the alarm mode. For
example, when this value is set to 45 degrees, the unit will enter alarm mode when the unit is
tilted by 45 degrees or more. This parameter can be set to any value between 20 and 90 degrees
in 5 degree increments. The default value of this setting is 60 degrees.
6.1.4 Time Before Warning Tone
Once the Alarm Tilt angle has been exceeded the unit will first enter a time before warning
mode. This will give the wearer a brief amount of time to react incase the device was
accidentally tilted such as may happen when sitting down or when taking the device on and off.
The value of this parameter determines how long after a tilt condition is detected does the device
wait before sounding the warning tone. This value can be set in one second increments from 0 to
10 seconds. The default value is 5. Caution: If this value is set too low (e.g., 1 - 3 seconds) the
unit may frequently emit warning tones when the wearer walks or is engaged in any activity that
may cause motion of the PPD. A value in the range of 3 - 5 is more practical for most
applications.
6.1.5 Alarm Time After Warning
The value of this parameter determines how long the unit waits after starting the warning tones
before it transmits an alarm message. If the unit is accidentally tilted, this value sets how long the
operator has to upright the unit before an alarm message is sent. This value is set in 5 second
increments from 5 to 30 seconds. The default value is 5 seconds.
6.1.6 Warning Tone Enable/Disable
The value of this parameter determines how the warning tone behaves when the unit has entered
the warning mode. This parameter can be set to one of three possible values:
No Tone
The device will not issue a warning tone (not recommended).
Single Tone
The device will issue a single, short beep at the start of the warning mode.
Continuous (default)
The unit will emit warning beeps during the warning mode until it transmits the alarm signal
(e.g., the warning mode time period set by Alarm Time After Warning).
6.1.7 Alarm Tone Enable/Disable
This enables/disables the hi-lo tone to signify actual alarm transmission. The default is enabled.
