The Cygnus input/output unit has been designed for interfacing with other fire systems, turnstile gate entry systems and door release systems. In the case of an alarm activation, the interface will trigger the door release and will deactivate the turnstile so a quick evacuation can be made to the assembly point. Where a site has a biometric security system the interface can provide the trigger to print out a fire register from the security log. For more information call our technical team.
