2.5 Working state for the FGS02 Socket

1. Normal

When put the FGP02 plug in the FGS02 Socket, there is green indicator light for each sensor and output the normal working signal;

2. Alarm

When put the FGP02 plug in the FGS02 Socket, there is red indicator light for the corresponding sensor which is in the alarm status; the buzzer sounds, at the same time the unit outputs the alarm signal;
