15W Self Amplified 24 Volt Horn (Catalog Category: Installation Equipment / Bogen Accessories)

Piece of cake to install with the SNOM PA1 VOIP unit and an extra wall adapter for the power. The built in amplifier is extremely powerful – we have it set for about 1/3 volume for the warehouse, still very loud 200′ away from unit. Also, even though not prime, the vendor got it to us quickly in good shape, well packaged .
