Summary for the User

The ALM100 is the "voice" of your boat's safety system. It is particularly useful for sailors who might be away from the helm or for powerboaters who need a secondary alarm in the cabin or engine room. Its IP67 rating makes it rugged enough to be mounted anywhere on the vessel.
