How to use the 2G/3G Portable PIR Alarm
Once you have positioned the pir sensor, installed the simcard and programmed the
numbers the system is ready to use.
The GSM Portable PIR Alarm has two modes, alarm mode and auto mode. In alarm
mode you have to arm the alarm manually when required. In auto mode, the alarm is
always armed. You can choose the best mode that suits your requirements.
These modes are selected by sending the text message as follows.
#
mode
=
1
#
Alarm Mode (default)
#
mode
=
2
#
Auto Mode
Mode 1 - Alarm Mode:
#
mode
=
1
#
Alarm mode is the default mode. You will need to set the alarm to ON before it detects
movement and sends an alarm message.
To set the alarm to ON you will need to send the text message
#
ALARM
=
ON
#
This will activate the alarm.
#
ALARM
=
ON
#
This will deactivate the alarm.
It is important to remember that when the alarm has been triggered you will need to reset
the alarm by sending another text message
#
ALARM
=
ON
#
Mode 2 - Auto Mode:
#
mode
=

#
The alarm is always armed and will trigger when movement is detected. It will
automatically reset back into armed mode after 20 seconds of no movement being
detected.
