ESIM022 User manual v1.1
4. GENERAL OPERATION DESCRIPTION
GSM dialler ESIM022 uses the GSM network for event transmission by SMS text message. When
one of the two available preset numbers dials the system, it answers the call and the user can
listen for up to 60 seconds to what is going on in the premises. This function operates only when
a microphone is connected. The system will ignore SMS requests and phone calls coming from
unknown phone numbers.
The system has 2 digital inputs (normally closed or normally open) for alarm system’s PGM output
or detection device connection, such as magnetic door contact. By connecting the input to the
non-GSM alarm system’s PGM output, you will be able to receive an SMS text message or pho-
ne call regarding system alarm/restore, arming/disarming and other events depending on alarm
system configuration. In addition to being informed by SMS text message or phone call regarding
alarm and restore events of the inputs, the users can control one electrical appliance by connec-
ting it to the open-collector output. For example, users can turn ON or OFF the heating, lighting,
lift the gates, blinds etc. The output can also be used for arming/disarming by connecting it to one
of the alarm system zones configured as a keyswitch.
The system is protected from sabotage by built-in tamper switch resulting in user notification by
SMS text message if the enclosure is tampered.
ESIM022 can be equipped with an external temperature sensor for temperature monitoring.
The system may be equipped with a back-up battery allowing to maintain the power and notify
the user by SMS text message regarding mains power loss and restore events.
