The annunciator has a built-in low level sounder to signal when there is water detected. Green LED for no water detected, yellow LED for disarmed and red flashing LED for water detected. The single push button is used to silence, clear or disarm panel. There is an on-board relay to turn off a main valve if water is detected so flood damage can be eliminated.
