9.2 Sensor Activity Alerts - iSocket

Alarm Notifier

iSocket

Alarm Notifier

a feature of the iSocket device which will notify you in the

event of a break-in and some other case. You can receive notifications in various ways.
iSocket GSM 706/707 can call you or send an SMS when the sensor is triggered. You
can also be informed by SMS on each change of sensor's status (change of logical
value).

If you have configured notifications by messages the device will send messages to all
numbers. If call alerts are configured, the device will call you within about 20 seconds. If
you pick up the handset the microphone will be activated and you will hear sounds from

the  room.  If  you  don't  pick  up  after  20  seconds  the  device  will  try  to  reach  the  next
number  on  the  list.  The  device  will  only  try  to  call  each  number  once.  The  call-
notification cycle is considered complete as soon as someone answers or hangs up. If no
number  is  reached  during  the  call-cycle,  the  device  will  send  messages  to  all  alert-
numbers,  thus  completing  the  notification  cycle.  SMS-notification  cycle  is  considered

complete as soon as all messages have been sent by the device. Therefore the most
important numbers for notifications have to be placed at the beginning of the list.

Only one alarm within 60 seconds is indicated. This means that if two (or more) sensors

were activated within one minute, you will only get the one alert. During the notification
cycle the device will not detect new sensor triggering. The device will be ready to detect
sensor activity no later than one minute after completion of the notification cycle. If the
sensor is still active at this time the device will start a new session of notifications.

For these reasons the

ALERT=CALL/SMS

is the ideal option for many PIR sensors, which

changes its logical "0" to logical "1" value and back to "0". In this case only one alert is
generated and you receive a notification. However, this setting is not suitable, for

example,  for  door  sensors  which  change  their logical  state  from  "0"  to  "1"  and  stay  in
this  state.  Since  they  remain  in  this  state  you  will  receive  endless  alerts  until  you
deactivate  the  alarm  function  with  the  command

ALARMOFF

. For sensors that change

their status and stay in that status, the option

ALERT=SMSCHANGE

was designed. With

this configuration you will be notified only once - when a logical value is changed.

The microrelay will be active for the time configured by command MICRORELAYTIME.
However it will be deactivated as soon as someone picks up the phone during the call-

notification cycle. The microrelay is active only if the alarm function is active.
