Brunel University has contracted Tyrrell Systems to upgrade their existing graphics fire alarm monitoring system that is predominantly hard wired to a fully resilient IP network. The site fire system is being gradually upgraded from Kidde fire panels to Kentec. The client required both fire systems to run seamlessly together on the same GUI as the upgrade takes place. Each fire panel is now connected independently via a fire IP interface which has eliminated the need of the old hardwire network and we can easily change the driver to suit as the panel upgrade takes place.
