NEXUS is a battery powered, wireless critical alert system. The units are fully portable, wire free, and can be rapidly deployed for fire alert and lockdown situations.
When one NEXUS unit is activated, all units within range that are on the same site will also be activated.
The NEXUS system boasts a robust 1km line of sight transmission range between units and a long battery life of up to 3 years, with a maximum of 64 units operating on one site.
Each unit acts as a repeater to form an advanced wireless mesh network, allowing for up to 16 mesh hops between units; this gives the NEXUS system a maximum range of up to 16km.
Each site requires at least one master unit, which is fitted with a manual reset key. Resetting the master unit will reset the system post-activation, however, the initially triggered unit will continue to flash until it is manually reset.
NEXUS units can either enunciate a bespoke message or sound a simple alert, alongside a visual flashing beacon light. The decibel level of the enunciated message or alert sound can be adjusted to suit the environment.
NEXUS units are available in both internal and external options, with external units featuring a robust IP66 weather rating. External cages can be added to protect units from flying objects and debris.
When an IP Masthead is added to the system, NEXUS units can be monitored and controlled from one central location using the PC app. Silent tests can be initiated via the app, and units can be reset post-activation.
Email alerts can be set up so that 3 separate email groups can be notified under defined circumstances in the event of an activation.
The NEXUS Lockdown system is designed to give a clear alert in the event of an activation. Lockdown units are visually and audibly distinct from fire alert units to minimise disruption and confusion. NEXUS Lockdown units comply with Ofsted lockdown procedure guidelines that fall in line with advice from the National Counter Terrorism Office, which state that ‘the use of fire alarms should be avoided to reduce incorrect responses to an incident’.
Lockdown units can enunciate a bespoke lockdown message that can be fully customised at the time of ordering. Alternatively, units can be ordered with a sounder that has 32 different alert sounds to choose from. Either variant is paired with a visual flashing beacon light.
Why choose the NEXUS Lockdown System?
The Background As part of the Ofsted inspection, schools will be asked if they have a Lockdown Policy – this can be a simple document with guidelines – they have not had to have an actual Lockdown system in place. However, we have recently learned that Ofsted now advocate a dedicated lockdown alarm to be in place, distinctive to the sound of the fire alarm.
