The patented PIR intruder functionality is available on all Cygnus alarms. This additional feature helps utilise fire, first aid alarms and detectors for intruder activations. Alerts can also be sent to a user or third party monitoring station through a GSM Auto Dialler or other monitoring equipment. The sensors are activated by using the menu settings on the control panel and if an intruder passes the sensor when in activation mode it will cause the local alarm to sound. To order this additional functionality to any Cygnus alarm units, add PIR to the product code.
