The NEXUS Emergency wireless alarm system uses a secure wireless mesh protocol to provide a long-range, robust system, designed to alert personnel to anything from threats, fires, danger or emergencies. A combination of loud audible tones and flashing lamps will ensure safety is always maintained. With a wireless range of 1km line-of-sight between units, and a maximum of 16 mesh hops, the NEXUS alarm system has a potential range of 16km. There is a maximum of 64 units per site, and when one NEXUS unit is activated, it will trigger ALL units in range to sound an audible emergency message, accompanied by a flashing beacon light.

The NEXUS wireless alert system from Cotel is aimed at schools, colleges, sport centres and other places where public access is provided. In the event of an incident requiring rapid action on-site, it can provide immediate action by first responders designated by the organisation.
Silent test mode functionality is built in to minimise disruption and can be activated from any one of the NEXUS units using the key switch, or remotely when using an IP Masthead.
Intelligent power saving technology ensures a long battery life of up to three years, keeping service calls to a minimum and reducing the environmental impact. A low battery alert is available via the IP Masthead, as well as on each unit.
