Nexus External Wireless Master Call Point Sounder & Strobe Blue


The new NEXUS Wireless Alert system from Luminite is aimed at schools and other places of learning as a lockdown system in the event of an incident requiring rapid restrictions to a site. It is quick and easy to install with no civil works or cabling required and is fully portable. This is a battery powered system that will, when activated, give an audible and visual Lockdown alert with the aim of minimising disruption to the learning environment whilst ensuring the safety of pupils and staff.

  • Battery powered (not included, order part 414-0059)
  • Rapidly deployable and reusable
  • Wireless with up to 250 units on one site
  • Long range transmission of 1km between units
  • Visual beacon and audible lockdown message
  • Works on advanced wireless mesh protocol negating the need for repeaters
  • IP Masthead receiver available for remote monitoring
  • 3 year battery life with low battery alerts

NEXUS uses a secure wireless mesh protocol to provide a long range, robust system, designed to alert occupants to a threat on or near their site requiring a lockdown procedure to be implemented. With a wireless range of 1km line of sight between units, and a maximum of 16 mesh hops, NEXUS has a potential range of 16km. There is a maximum of 250 units per site, and when one NEXUS unit is activated, it will trigger all units in range to sound an audible lockdown message, accompanied by a flashing beacon light.

An IP Masthead can be added to the system so that up to 250 units can be monitored and controlled from one central location. This can be, for example, the site office computer or a Central Monitoring Station (CMS). To facilitate this function, NEXUS provide a dedicated PC and mobile app. Additionally, you can assign a name and location to each unit, ensuring a quick and efficient reaction to any alert event. You can also integrate with Immix and other popular CMS platforms. Please see diagrams for an illustration of the options available.

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.

In all instances of activation, both the sounders and flashing beacons will continue until reset, however, the initial triggered unit will continue to flash until the call point button is manually reset.

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.

NEXUS is available in both internal and exvternal options - external units are fully weatherproof to IP66 standard.

Instances of when NEXUS may be used include:

  • A reported incident in the vicinity
  • An intruder on site
  • Air pollution or any kind of airborne contaminant
  • Dangerous dog or animal in the vicinity

It is vital that schools have a lockdown procedure in place alongside their fire procedures. The aim of any school lockdown is to prevent pupils or staff moving into danger areas and preventing or frustrating the moves of a potential attacker. The NEXUS system uses voice enunciation which differentiates from an evacuation alarm.

The National Counter Terrorism Security Office (NaCTSO) offer detailed guidance notes for developing an effective lockdown procedure.
