GSM-252 ESIM-252 GSM Auto dialer, text & voice notification

GSM-252 – auto dialler, used to inform users through GSM network that alarm has occurred. System can control one electric appliance via relay. GSM-252 can be connected to any control panel. If PGM or Bell are activated warning call is dialed and SMS message is sent to preset phone numbers.
Taking our popular GSM-151 and upgrading it with the latest generation GSM module (SIM900) to give the unit quad band capability as well as pre-recorded call playback and an additional relay making it two.

System application examples:

Object security option protects your home 24/7 and instantly informs about unauthorized entry by SMS and call to the cell phone.

Information about water-supply accident (flood detection) prevents from damaging your personal assets and those of your neighbours in case of accident water overflow from the water-supply system.

Electrical devices control by SMS or free Call - ability to remote control electrical sauna, water pump, boiler, watering device, switch on or off the lighting, heating and else.

Sound channel usage option allows the user to hear what’s going on in the secured premises through own cell phone.
