The TECNOCELL 4 communicator is compatible with old and new generation Tecnoalarm systems.
It can be connected to a control panel via RS485 serial bus or, instead, by means of a dedicated
RS422 serial bus and the optional ESP GSM LINK interface. In this way, it emulates the operation
of an internal GSM interface and replaces the ESP GSM 4G interface of the control panel.
This operating mode allows to decentralize the position of the communicator to obtain two
advantages: maximize the signal power and increase the intrinsic security of the system
by installing the communicator in a hidden location.
