3. CONSTRUCTION, ASSEMBLY AND INSTALLATION
3.1. Receiver construction
The receiver consists of a splash-proof surface-mounted housing with a screw-in GSM antenna and a main
board. The main board (Fig. 1) has an executive system implemented on two relays and screw connections for
connecting the supply voltage, controlled devices and sensor outputs and control buttons. The board contains
memory on a base. Placing the module on the base makes it easier to transfer the memory to another receiver,
for example in the event of a device failure.
