ALARMS
4.6 ‘MAN DOWN’ (MOTION SENSOR) ALARM
The motion sensor alarm can be configured ‘NOT USED’
(default), ‘SELECT AT START’ or ‘ALWAYS ON’ , as detailed
in ‘CONFIGURATION HANDBOOK’ CD-ROM (Part No.
64193).
The sensor will activate an alarm if the instrument is not moved
for a pre-set period, configurable from 30 seconds to 90
seconds in 1 second increments.
The ‘Man Down’ alarm has a pre-alarm feature that alerts the
user that alarm activation is imminent. This pre-alarm time is
not adjustable and activates 10 seconds before the ‘Man Down’
alarm.
e.g. if configuration of ‘Man Down’ alarm is set at 30 seconds,
the pre-alarm activates 20 seconds after last detected
motion.
The pre-alarm countdown (in seconds) on the display,
illustrated in Fig. 4-16, together with an audible ‘beep’ and
corresponding flash of red LED’s, precede the ‘Man Down’
alarm, illustrated in Fig. 4-17.
Fig. 4-16 Pre-Alarm
If the pre-alarm countdown reaches zero and is not reset, by
movement of instrument, then the ‘Man Down’ alarm will be
activated and logged.
