Description:
The top line shows the „shock impulses" above the set shock threshold „8/10". Above it, it has been marked from when
onwards which „SHOCK" settings are valid.
The middle line shows the „IDLE TIMER" described in the chapter on the command „IDLEALARM". The „IDLE TIMER"
defines the shortest distance between two text message alarms. This is particularly important for fast alarm sources
that would otherwise cause many alarm messages to be sent before you can react (e.g. shock from movement of a
stolen vehicle).
The bottom line shows when the sensor would trigger an alarm message („ALARM SMS") at the valid settings and
which ones would be blocked by the „IDLE TIMER" („IDLE").
„SET SHOCK #1513" (without time) or „SET SHOCK 1 #1513" ( time = 1 s) cause immediate alarm once a shock is
above the threshold. The shock is measured at 250 kHz. When the alarm is triggered, the „IDLE TIMER" is started
at the same time. During this time, the sensor cannot trigger a new alarm even if the condition for a new alarm would
be present.
„SET SHOCK xxx #1513" (xxx = time indicated in seconds) requires all (!) sensor values to be above the shock
threshold within these, e.g., 10 seconds.
Observe that a measurement takes place every second. Accordingly, the vibration must not cease or drop
below the sensor threshold for more than 1 second since this would restart the time indication (10 se-
conds).
This also applies to inverted mode („INV"), where a time needs to be indicated as well. However, the distance between
the shocks is measured here. If the time sets above the set trigger time, an alarm is generated.
