The Cygnus fire call point alarm operates using a single battery pack and can be used externally. This radio alarm device has also been designed as a standalone alarm unit. These devices are normally situated around a site in prominent places on main escape routes, stairwells and on, or near fire points where they are visible in case of an emergency. This alarm has a 110 decibel sounder and an LED beacon for visual alerts. The call point is resettable and can be programmed with a sounder delay. Activating a call point will result in a site wide alert.
