Function:
ESIM021 is a microcontroller based device used to inform users about the alarm in automatic or security systems and control one electric appliance – open collector.
Operation description:
The GSM security and control system ESIM021 uses the GSM network for transmission of inputs (alarms generated by one of the system zones) to authorised users. In addition to being informed about triggers/resets of the inputs, the users can manage the system and use the system to control one electronic device.
The system has two digital inputs (normally open) called Zone1 and Zone2. ESIM021 can also control 1 electronic device (using an open collector) on receipt of the correct SMS text message from one of the authorised users. For example, users can turn on or off the heating, lighting, lift the gates, blinds etc. The system remembers the output setting if there is a temporary electricity failure. Once initialised, ESIM021 will function 24/7.
When an authorised number calls to the system, the device answers and the user can listen for 2 minutes to what is going on in the premises. This function works only when a microphone is connected. This microphone does not include into standard package content. The system will ignore SMS requests and voice calls coming from unknown telephone numbers. Users can be informed about triggered/reset inputs by SMS (see chapter 1.2.4) or CALL methods (see chapter 1.2.5). Users also can enable and disable either input (see chapter 2.2). Any number format can be used, for example +37011111111, 861111111 or even short numbers like 111. International numbers must be entered with „+“ or „00“.
