Step 3: Calling time
This is the time the unit will spend attempting to call a number before aborting the call and calling
the next number on the list. It is very useful to adjust this time so that if there is voicemail or
answer machine on a number, that the intercom aborts the call before the machine picks up,
otherwise the unit will think the call is answered and never call the next number. To adjust this
time
, send the following SMS messages…
*12*1234#
52
??
#
(Where ?? = ringing time in seconds 10-99. Default = 20)
TIP:
Remember to include the network connection time. A mobile phone needing to ring for 10
seconds may need a programmed ringing time of 15 seconds, because it can take 5 seconds to
connect the call.
Step 4: Caller ID access control
This feature allows up to 100 numbers to be stored in memory. Any of these numbers can call the
intercom. It will recognise the number, end the call without answering, and activate the output
relay, all within a few seconds.
Now you may add numbers which can call the unit to trigger the relay by sending the following
SMS (up to 3 phone numbers can be sent in a single SMS…
*12*1234#
72
telephonenumber
#
72
telephonenumber
#
72
telephonenumber
#
Just send the complete number as you would normally dial it from a phone.
Tip:
Even if a number is stored as a dialling out number when the call button is pressed, it needs
stored again under the 72 feature if it is also required to have caller ID access.
Important
:
Some US networks automatically insert the long distance 1 in front of a number
when you call it on your phone, and some do not. You may need to enter phone numbers
in this section either with, or without long distance 1 in front. Please try both methods to
see which works in your area.
E.g. number 702-999-9999 may need stored as 1-702-999-9999.
First you must tell the unit which country it is operating in
by entering the country code of your country. If you do
not know the country code, it can be found online. Some
examples are shown below..
UK - 44
USA - 1
The example shows USA country code being entered.
TIP: Do not add any leading
zero’s in front of the country
code.
