Radio message receivers with a signalling function will remain indispensable for authorities and organisations with security tasks (BOS) in the future. Working independently of mobile phone networks, they serve fire brigades and rescue services in urban and rural areas equally well when it comes to eliminating hazards and saving lives.

While analogue paging receivers are still widely used in Germany, digital paging receivers allow alarms to be raised particularly efficiently. The latest generation of DME devices, which can transmit specific mission information together with the alarm, have proven to be particularly helpful in emergency operations and offer numerous practical features.

Digital Message Receivers (DME – Digitale Meldeempfänger)

For efficient alerting, digital message receivers addressed by means of the POCSAG protocol offer the best prerequisites. These devices are not only tap-proof, but also independent of any overloaded analogue radio channels.

The product range of Fischer Siren Construction + Alarm Systems includes digital message receivers (DME) up to the highest configuration level DME III, which allow an acoustic voice output parallel to the text display. The POCSAG receivers we offer are already proving their worth in everyday use by numerous fire brigades and rescue services.

Detector tester for analogue and digital pagers

Developed at the suggestion of Fischer Siren Construction + Alarm Systems, the innovative BOS device tester makes it easy to check all your message receivers – whether analogue or digital. If you are about to switch from analogue 5-tone to digital POCSAG alerting, you are already equipped with our detector tester!
