Flashing lights and sirens are connected to the control panel and provide a warning when the curtain is about to descend. When the fire alarm goes off and the fire curtain descends the beacon will flash and a sounder will go off until the signal from the alarm is lost. Please note that when used in isolation the audio visual unit does not stop the fire curtain descending or retract the curtain.
