Cygnus Wireless Alarm System Cygnus by Checkpoint, is new technology in wireless emergency fire detection/alarm systems, evacuation systems, first aid nurse call systems combined with security functionality for construction sites. The Cygnus wireless alarm system has been designed and developed in conjunction with major construction companies to incorporate all features required for larger construction projects needing temporary first aid/nurse call, evacuation, security and fire detection alarm systems. As a result, the Cygnus fire alarm system is able to link no less than 480 units in 15 zones. This can be a combination of individual units of either a fire alarm call point, evacuation call point, first aid alert/nurse call point, smoke detector, heat detector and the new combined call point/first aid alert alarm. Any of the Cygnus wireless alarm system call points can be fitted with security sensors to protect your site 24/7 from unauthorised entry.
