Is there a way to adjust the threshold of time after which the sensor will report the absence of motion?
thanks
Joe
The default is 30 seconds. You need to set several parameters on the Device Option tab if you want to go shorter. Here is a snippet from the manual. You are going to want to reduce Parameter 6, (but if you go below 8 second you also have to reduce parameter 2).
-
MOTION SENSOR?S SENSITIVITY
The lower the value, the more sensitive the PIR sensor.
Available settings: 8 - 255
Default setting: 10
Parameter size: 1 [byte] -
MOTION SENSOR?S BLIND TIME (INSENSITIVITY)
Period of time through which the PIR sensor is ?blind? (insensitive) to
motion. After this time period the PIR sensor will be again able to
detect motion. The longer the insensitivity period, the longer the
battery life. If the sensor is required to detect motion quickly, the time
period may be shortened. The time of insensitivity should be shorter
that the time period set in parameter 6.
Available settings: 0 - 15
Formula to calculate the time: time = 0.5 x (value + 1)
Default setting: 15 (8 seconds)
Parameter size: 1 [byte] -
PIR SENSOR?S ?PULSE COUNTER?
Sets the number of moves required for the PIR sensor to report
motion. The lower the value, the less sensitive the PIR sensor. It?s
not recommended to modify this parameter settings.
Available settings: 0 - 3
Formula to calculate the number of pulses: pulses = (value + 1)
Default setting: 1 (2 pulses)
Parameter size: 1 [byte] -
PIR SENSOR?S ?WINDOW TIME?
Period of time during which the number of moves set in parameter 3
must be detected in order for the PIR sensor to report motion. The
higher the value, the more sensitive the PIR sensor. It?s not
recommended to modify this parameter setting.
Available settings: 0 - 3
Formula to calculate the time: time = 4 x (value + 1)
Default setting: 2 (12 seconds)
Parameter size: 1 [byte] -
MOTION ALARM CANCELLATION DELAY
Motion alarm will be cancelled in the main controller and the
associated devices after the period of time set in this parameter. Any
motion detected during the cancellation delay time countdown will
result in the countdown being restarted. In case of small values,
below 10 seconds, the value of parameter 2 must be modified (PIR
sensor?s ?Blind Time?).
Available settings: 1 - 65535
Default setting: 30 (30 seconds)
Parameter size: 2 [bytes]
thanks, I’m actually trying to go the other direction, i want to go to 5-10 minutes (want to use it to turn off lights if nobody is in the area)
I think parameter 6 should do this
Sorry fixed the crossed out hard to read text. Hope it works out for you. Parameter six is right.
