Alarm and control system ESIM021 is used to inform a maximum of two users through the GSM network that an alarm has occured. 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.
ESIM021 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 ESIM021 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 ESIM021 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.
