The Cygnus 85 decibel fire call point alarm operates using a single battery pack and is IP rated, thus suitable for external use. This device has been designed as a standalone alarm unit as well as a radio alarm. These devices are built with a less audible sounder for quieter areas such as operational facilities where a 110 decibel level is inappropriate. The call point is pushed to raise an alarm which will activate alarms around the entire site. This device does not include a flashing beacon.
