The ALERTEX Lockdown system is a wireless critical alert system, 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.
Lockdown units comply with current guidelines from NaCTSO, which state that ‘the activation of the fire alarm to initiate evacuation should be avoided to reduce the possibility of an incorrect response’.
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.
As most Alertex Lockdown installations take place during school holidays, here is a list of forthcoming term times for England:

11 April 2025 – 28 April 2025
The ALERTEX call-point with either a sounder/beacon is a staple in any setup. When the call-point button on the unit is pressed, all units on the same site within 1km will be activated. The master variant is fitted with a reset key which will deactivate the ALERTEX system post-activation. External units have an IP66 weather rating and are both water and dust resistant.
The ALERTEX sounder/beacon can play one of 32 different alert sounds, and is paired with a flashing beacon. The unit features no call point and is activated when a call-point or keyfob on the same site is triggered. The volume of the sounder is adjustable up to 117 dB.
The NXVS Voice Annunciator provides a site wide audible alert for lockdown, fire, or any other hazard. Users can choose from a library of prerecorded sound or voice messages, or they can record their own. Crucially, an ‘All Clear’ can be sounded post event. The NXVS is fitted with white flashing strobe lights which automatically turn on when the system is activated.
The ALERTEX wireless call-point can activate any ALERTEX sounder / beacon or annunciator units on the same site within a 500m radius. It requires no wires or cabling and is battery operated.
The ALERTEX key fob acts as a portable call-point and can activate ALERTEX sounder / beacon or annunciator units on the same site when used within 100m of a repeating unit. The key fob is supplied with a lanyard and breakaway clip.
