The robust plastic housing material keeps the siren's internal mechanism protected against accidental knocks and shocks for an enhanced service life.

• Minimum acoustic service life of 5,000 hours for long-lasting performance
• IP65 (ingress protection) rating means it's protected against dust and low-pressure water jets
• Light weight of 121g to minimise strain on your signal tower

• Haulage and logistics industry
• Mobile equipment
• Secure doorways

A pulse tone siren like this one cuts more effectively through the continuous ambient noise that's common in many workplaces. This gives your operators the best chance of hearing the alert and taking swift, appropriate action.
