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 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
“withheld 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.
SET AUXILIARY OUTPUT AO TIME (A1T, FOR A1M = 01 ONLY)
The auxiliary output AO time can be set from 01 - 99 seconds or latching (set the AO output time to 00 for latched mode. In latch
mode the AO output will stay triggered until the relevant command is sent again to unlatch the AO output. This option is only
available when the AO output mode,
A1M
, is set to mode 01. Please refer to the
A1M
commands below for more details).
1111A1Tnn
Store the AO time nn = time in seconds (e.g. nn = 05, time = 5 seconds).
1111A1Tnn?
Store the AO time nn = time in seconds. Also send a confirmation text back to the sender.
1111A1T?
Query the current stored AO time. A text message will be sent back to the sender showing
the stored AO time.
