4 Channel GSM Receiver Module,great for multiple users as with this easy to program gsm unit you can open the gate with mobile phone,no need for handsets by phone call or text.,along with radio control as well.
It can control various types of systems ,such as alarm systems,garden irrigation systems or other controlled devices.
The system is operated by entering a certain number of (telephone) users in the receivers SIM card. Each user will then be able to control all the functions for which the unit has been programmed for.
Associating the number of possible users,the settings associated with the telephone numbers(saving/deleting/editing the settings)and saving thye rolling code transmitters may be done without having to access the control panel and does not require the survey of an operator,as they may be done with a mobile phone.
Call allows to associate a function that can be activated with a missed call(no charges)to one of the 4 channels. So the activation of a control by a user is made possible by means of a simple call free of charge.(for instance opening the gate,switching on lights or disarming and alarm system).
The built in display allows to customise the function of each relay: monostable,bistable or timed up to 600 seconds.
If the alarm system is associated with one of the four channels,Call is designed to call a pre-set user ,in the event of a suddern activation of the alarm itself.
The alarm system can be deactivated by a user authorised to access this function via mobile phone. The imput for buffer battery with 12 Vdc (optional) with intergrated recharge control guarantees operation of the receiver even during a power cut.
