The GA902 noise activiated warning sign is designed to warn personnel when noise levels exceed a pre-set level. Wearing ear defenders is not always popular with staff exposed to industrial noise and this unit offers the advantage that they need only be worn when necessary. Warning text is normally supplied to the EC requirements but alternative screens in any language can be supplied to order. Slave units are available where a large area requires coverage.
