Programming the GSM Intercom
nnn
is a button number between 001 & 050. The telephone number y can be a maximum of 30 digits. For example: to store the
number 01912243174 for button 5 and three divert numbers (if that one is not answered or busy) of 01912241558, 07771234567
and 01912241559 respectively, the following SMS messages would be sent to the GSM intercom:
1111STN005”01912243174”
1111STD005”01912241558”
1111STE005”07771234567”
1111STF005”01912241559”
STORING A TELEPHONE NUMBER FOR DIAL IN DOOR RELEASE (STR)
Dial in door release allows users to release the door/gate simply by dialling the telephone number of the SIM in the GSM PRO
intercom panel. The intercom panel will check the callers ID when it receives a call and if it matches the list of stored numbers, it will
clear the call down (avoiding the caller being charged for the call) and will activate the relay for the programmed time. Up to 1000
numbers can be stored. The messages to check, store or delete numbers are as follows.
1111STRnnn”yyyyyyyyyyy”
Store the telephone number yyyyyyyyyyy in position nnn, where nnn = 000 - 999.
1111STRnnn”yyyyyyyyyyy”?
Store the telephone number yyyyyyyyyy in position nnn, where nnn = 000 - 999, and
send a confirmation text message to confirm storage of new number.
1111STRnnn?
Query the telephone number stored in location nnn, where nnn = 000 - 999. A text
message will be sent to the sender with the stored number for that location.
1111STRnnn””
Delete the telephone number stored in location nnn, where nnn = 000 - 999.
1111STRnnn””?
Delete and confirm deletion of a telephone number in location nnn, where nnn = 000 -
999.
IMPORTANT NOTE: It is important to switch OFF voicemail and automatic SMS features on the SIM card in the GSM intercom
when using this feature (see the ‘Forced Dial’ section for more details). Also note that it will not be possible to use the dial in to
speak facility from a number stored to release the door/gate when dialling in (door release takes priority).
Please also note it is important that the number stored, when dialling in to release the door/gate, must have any “caller ID” or
“withhold number” function switched OFF on the telephone/mobile that is making the call to the GSM intercom. If this feature is
not switched OFF the GSM intercom will not recognise the caller’s number.
SET CALL TIME (SPT)
The call time is the maximum time in seconds that a call can last before the intercom panel automatically clears the call down. The
time can be from 20 seconds up to 240 seconds (4 minutes) and begins from when the call button is pressed. The default time is 40
seconds. The following messages are used to set/check the maximum call time.
1111SPTnn
Store the time nn x 20 seconds (e.g. nn = 03, time = 60 seconds).
1111SPTnn?
Store the time nn x 20 seconds (e.g. nn = 02, time = 40 seconds. Also send a confirmation
text back to the sender.
1111SPT?
Query the current stored time. A text message will be sent back to the sender showing
the stored time (remember to multiply the number in the received text by 20 seconds).
nn multiplier:
nn = 01, time = 20 secs
nn = 02, time = 40 secs
nn = 03, time = 60 secs
nn = 04, time = 80 secs
nn = 05, time = 100 secs nn = 06, time = 120 secs
nn = 07, time = 140 secs nn = 08, time = 160 secs nn = 09, time = 180 secs
nn = 10, time = 200 secs nn = 11, time = 220 secs nn = 12, time = 240 secs
SET RELAY TIME (RLT)
The relay time can be from 01 – 99 seconds or latching (set the relay time to 00 for latched mode. In latch mode, the relay will stay
energised until the command is sent again).
1111RLTnn
Store the relay time nn = time in seconds (e.g. nn = 05, time = 5 seconds).
1111RLTnn?
Store the relay time nn = time in seconds. Also send a confirmation text back to the sender.
1111RLT?
Query the current stored relay time. A text message will be sent back to the sender
showing the stored relay time.
