GSM 12A

GSM 12A : SMS-operated Alarm and Switch Control

For 12 volts environments: photovoltaics, vehicles, boats, other special applications

Send commands to GSM 12A by SMS to remotely control appliances through its 2 outputs: heating (e.g. with Alde® heating systems for caravans and motorhomes), hot water, lights, pumps, inverters, computer equipment, etc.

GSM 12A monitors temperatures, detectors and power supply voltage, and sends an alarm SMS to a phone number of yours when needed.

  • Remote control of:
    • 2 outputs (remote-controlled switches) of 16A
    • 2 analogic inputs for temperature sensors
    • 2 digital inputs for detectors of your choice (fire, flooding, gas, burglary, fault indicator, etc.)
    • voltage level of power supply (12V)
  • Sends alarm/notification messages per SMS to your phone.
  • Personal access code for protection.
  • Optional extensions:
    • AGG-3: power generator (genset) controller
    • temperature, water, smoke, gas, burglary, motion detectors

Included: a GSM antenna and a temperature sensor.

GSM 12A requires a valid SIM card from a mobile phone operator.

Operating voltage: 7.5V - 15.0V DC. Max load per relay: 16A (max 50V). Power cons.: 60 mA (standby), 250 mA (typical when active), +30 mA (per active relay). GSM: Dualband 900/1800 MHz. Operating temp.: -20 to +50 ºC. LxDxH: 114 x 26 x 65 mm. Weight: 120g. Complies with the European R&TTE directive. GSM 12A is designed for indoor use only.


AGG-3

AGG 3 : Power generator (genset) controller

Extension module for Sikom GSM 12A

Control your power generator by SMS!

  • Compatible with most petrol and diesel-driven generators.
  • Only usable in combinaison with SMS-operated switch GSM 12A.
  • Outputs: 3 relays 50V - 16A for controlling resp ignition, start, and connection of the load to the generator.
  • Input for monitoring of engine rotational speed (expects a value between 0V and 15V, for determining when the generator is running steadily).
  • Parameters adjustable by SMS: delay before disconnecting the starter motor, delay before connecting the load, and voltage threshold for start detection.
  • 2 buttons for locally starting/stopping the generator.

Available SMS commands: 3 commands for setting the startup parameters, and 1 for starting/stopping and requesting the current state.

Operating temperature: -20°C to +50°C. Operating voltage: 7.5-15.0V DC. Relays: max 16A/50V.
Consumption: 22mA (standby). LxDxH: 111 x 26 x 55 mm. Weight: 130g.
Complies with the European R&TTE directive. AGG 3 is designed for indoor use only.


FAQ for GSM 12A
No contact with the unit
  • Check that the unit receives power
  • Power off the unit, wait a few seconds, then power it on and try again
  • Check the antenna, and that the signal LED is green
The unit indicates a bad GSM signal
The GSM antenna should hang vertically, onto a non-metallic support.
There's no light in the Signal LED
  • Check that the SIM card works correctly
  • Check that the PIN code is deactivated
  • Check that the SIM card holder is not damaged
The alarm LED is permanently lit
The alarm LED remains red to indicate that the unit is set to dispatch any alarms that should be triggered on its digital inputs (command "A1"). It does not mean that an alarm has actually been triggered.
How do alarm activation and repetition actually work?
After alarm activation command "A1" has been received by the device, there is a delay of 1 minute before any alarm will actually get triggered. Do not forget to also activate the relevant detector input(s) I1 or I2 with command "B11" and/or "B21".

Once an alarm has been dispatched by SMS, a period of 60 minutes will elapse before any new alarm will be dispatched for that detector input (but you can cancel this delay if you wish, by reactivating the alarm with command "A1"). After this period of 60 minutes, a new alarm will be dispatched again by SMS if the detector still (or again) signals an alarm condition.

How to revert the unit to the factory settings?
If e.g. you forget your personal code, the factory-set code can be reinstalled. Do the following:
  • Disconnect the power supply.
  • Press and hold relay button 1.
  • Power up the unit and keep the button depressed for at least 10 seconds.
  • Release the button.
  • The unit has been reset and the personal code is now 1234.
I have no contact with my central unit when I really need it
If a unit is installed during the summertime in a place where the GSM coverage is weak, the signal will probably be even weaker, and possibly lost in the wintertime in case of substantial snowfall (this is especially relevant if the unit is located in a mountain area). This is because snow partly absorbs GSM signals. To prevent this from happening, check beforehand that the signal level is better than minimal (watch the color of the signal LED) when there is no snow around. You may mitigate the problem by moving the central unit to another room, or purchasing a better GSM antenna.
I sometimes lose contact with my central unit
Same answer as for the previous question, i.e. the signal may be so weak that it from time to time loses connectivity with the GSM network.
GSM Fixi V2

GSM Fixi : SMS-operated Switch Control

The no-nonsense solution for fixed installation in the fuse box

FAQ for GSM Fixi
The LED for output/relay 1 blinks red
A fault was discovered during the self-test procedure. Please contact your reseller.
The LED for output/relay 1 blinks green
  • Check that the PIN code is deactivated
  • Check that the SIM card is inserted in the right direction
  • Power off the unit, remove the SIM card and clean the contacts on the SIM card, e.g. with a rubber. Avoid touching its contacts while inserting it back into the unit. Power on the unit again.
  • Check with your GSM operator that your subscription is valid and/or that the SIM card is not out of credit.
I do not receive any SMS message from the unit
  • In case of a pre-pay contract: Verify with your GSM operator that the SIM card is not out of credit or even deactivated by the operator due to a lack of activity.
  • Try registering again the number to which the unit is to send its messages
  • Power off the unit, wait a few minutes, and power it on again
No contact with the central unit
  • Check that the unit receives power
  • Power off the unit, wait a few seconds, then power it on and try again
  • Check the antenna, and make sure that the signal LED is green
The unit indicates it receives a bad signal
The GSM antenna should hang vertically
When I activate a relay/output manually (using a push-button), it works one minute, then blocks for 20-30 seconds, then works again, and so on
There is probably a problem with the SIM card: either there is a physical fault, or the subscription is terminated. This symptom happens because the GSM module checks the network every minute, and if there is a connectivity problem, it will insist for 20-30 seconds, then abandon, then it will try again after 1 minute.
I have no contact with my central unit when I really need it
If a unit is installed during the summertime in a place where the GSM coverage is weak, the signal will probably be even weaker, and possibly lost in the wintertime in case of substantial snowfall (this is especially relevant if the unit is located in a mountain area). This is because snow partly absorbs GSM signals.
