GSM-021 ESIM-021 Auto dialer & text notification system

Alarm and control system GSM 021 is used to inform a maximum of two users through the GSM network that an alarm has occurred. Users may also control one electrical device via their mobile phones, e.g. they may switch a lighting system on and off or open and close a gate.

GSM 021 may be connected to an intruder alarm control panel. It has two digital inputs (normally open), so that one detection device may be connected independently of the intruder alarm control panel, or alternatively two detection devices may be connected to GSM 021 without needing a control panel.

When a triggered zone is restored to pre-alarm, the system also sends an SMS or voice message confirming that this has been done.

Either user may turn the heating or lighting on or off, open gates, lift blinds etc. by sending GSM 021 a text message. Only one electrical device may be controlled in this way. The system remembers the status of output in the case of temporary electricity failures. The system will ignore requests and calls coming from unknown telephone numbers.

Application examples:

Object security option protects your home 24/7 and instantly informs you about unauthorized entry using SMS and voice call to your mobile phone.
