Electronics Module<br />
The function of the electronics module is to power the unit either by AC mains supply<br />
or DC emergency battery supply, to control the gas module and read the gas module<br />
sensors. The main components are a power supply unit, a rechargeable battery, a<br />
main processor PCB, LED PCB, Valve/Sensor PCB and a LCD screen (touch<br />
screen). The LCD screen includes a back-light which is always on when the IFSD is<br />
powered. The touch screen displays information and receives inputs from the Operator<br />
via the touch screen keyboard.<br />
