Boat Systems

Siren and Strobe Light

Your boat might be equipped with a Whelen

flush-

mount siren and strobe light. The normal mounting
location is on the forward side of the control console.

Use the siren control head to operate the various
strobe, radio, siren, and public address features.

Refer to the

Whelen

operator’s manual for detailed

information about the siren and strobe functions.

The siren amplifier circuit is protected by a 10-amp
blade fuse located in the accessory fuse block inside
the control console.

Turn off the siren and strobe features when they are
not required to avoid discharging the house battery.

Turning the house battery OFF-ON switch to the

OFF

position at the end of your mission will cut power to the
siren amplifier and strobe circuits.
