GENERAL FEATURES GSM-21T is a GSM communicator mounted in a metallic case. Inside the case there is a 220Vac transformer, a back-up battery, and a compartment where the mobile phone (from Ericsson family - see „Usable GSM phones”) is to be placed, allowing the antenna to get out of the case. GSM-21T communicator can be used as an accessory for a burglary control panel with digital communicator or as a stand-alone alarm unit.
SMS format – example: “for the objective with code 0261, an alarm was detected on zone 2, disarm by code 1.
- it transmits events occurred at the objective protected by the burglary control panel only as SMS messages to the mobile phone of the objective’s owner; - it transmits events occurred at the objective protected by the burglary control panel both to a monitoring station and as SMS messages as well, to the mobile phone of the objective’s owner.
Note: The GSM phone connected to the GSM module is loaded from the module. GSM network specifications - can be used in any GSM authorized network Usable GSM phones: - Ericsson A1018s, T28. Other technical features - average duration of GSM communication: - active inputs by: - maximum current at “open collector” outputs: 8s; GND; 500mA.
- 16VAC: must be connected to the secondary winding of the power transformer; - LINE: must be connected to the phone dose; - TRBL: output; it goes high if telephone line is not OK; - DO1 … DO6: automation outputs (upon construction); - 12VDC:12V output; - IN1 …IN6: automation inputs. Note: If the green LED does not turn on or the GSM communicator is supposed not to function, do the next: 1. shut the GSM module down (both mains supply and 12V battery), and disconnect the GSM phone (JR1); 2.
Connection Scheme for GSM-21T GSM-21T programming Note: Before programming the GSM module, program the burglary control panel to phone line transmit events in DTMF formats (Ademco Express or Ademco PID) to the monitoring station. All parameters of the GSM module will be programmed from the GSM phone keypad: - optionally, the phone number of the monitoring station in case events are to be transmitted to the monitoring station; - optionally, the phone number of a different mobile phone (i.e.
- code generated for the periodical test. Notes: 1. SMS messages are implicit and automatically generated. Message issuing is not allowed in this software version. 2. SMS messages are available only for Ademco Express 4x2 format. 3.

Disconnect the GSM module from the power supply (both mains supply and 12V battery), if it was previously loaded. 2.
- press key “Yes”. 5.
- , (comma) - code generated by activation (ground connecting) of the sixth communicator input (2 HEX digits) - , (comma) - code generated by deactivation of the sixth communicator input (2 HEX digits) - , (comma) - code generated by GSM signal weakening (2 HEX digits) - , (comma) - code generated by the periodical test (2 HEX digits) - , (comma) - duration (in hours) the periodical test is performed at (2 decimal digits) - .
Any change of the configuration SMS is accompanied by a restart of the GSM module. Note: Format DTMF 4x2 describes events in such a manner that necessary information is presented by means of 6 HEX digits “AAAAEZ”, where: - “AAAA” is the client’s account number; - “E” is the event code; - “Z” is the zone/user number For format Ademco PID, the interface will not generate clear SMS messages. Notes: In the edit mode, digits can be obtained directly, by pressing the corresponding keys longer.
- press „NO” to exit the submenu. 7. Exit the mobile phone programming menu; Example for Ericsson A1018s: Press key „NO” for several times until the general message is displayed (indicating the used GSM network, and the current time and date, eventually). 8. connect the phone to the GSM module (JR1). 9. Power up the GSM module. In case of modifications, modify the configuration SMS, save it and erase the old one. Do all these when the GSM module is not powered.
