The NEXUS units are battery powered and have a long and robust transmission range of 1km between units. The systems are portable and quick and easy to install with no civil works or cabling required. Internal and external units are available in a choice of colours.

Silent test functionality is built in to minimise disruption and the system can be used in conjunction with the Luminite IP Masthead if off site monitoring is required. Each site requires at least one Master unit which is fitted with a re-set key. In all instances of activation, the initial triggered unit will continue to flash until manually re-set.

Each NEXUS unit utilises intelligent power saving technology to ensure a long battery life of up to three years, keeping service calls to a minimum and reducing the environmental impact. Remote monitoring and low battery alerts are facilitated when an IP Masthead is included in the system.

FIRE ALERT SYSTEM – this is aimed at construction sites, parks, utility sites, buildings undergoing refurbishment – anywhere requiring a robust warning system to fire, suspected terrorist attack or any other alert event involving evacuation. When one NEXUS unit is activated it will trigger all units in range to sound an audible evacuation alert as well as a visual beacon using a proven secure mesh protocol.

LOCKDOWN SYSTEM – this is aimed primarily at schools and colleges and works in a similar way to the Fire Alert but when activated will sound a LOCKDOWN message and visual beacon. This message can be customised prior to ordering otherwise the standard message will be supplied.
