The ALERTEX Wireless Critical Alert system is a robust wireless alert solution that operates over a secure, wireless mesh protocol. It is battery operated and requires no wires or cabling. The units are portable and rapidly deployable.

Up to 64 ALERTEX units can be used per site, with an impressive 1km line of sight wireless transmission range between units. Each unit acts as a repeater and the alert transmission can ‘hop’ up to 16 times across the mesh network, allowing the ALERTEX system to have a maximum line of sight range of up to 16km. ALERTEX units are highly energy-efficient and can last up to 2 years on a set of batteries.

The ALERTEX system can be used as a standalone system, comprising of one master unit and several slave units. The master unit features a master reset key the can be used the reset the system post-activation. 

The ALERTEX system can be monitored and controlled from one central location by adding in a Genesis IP Masthead to be used with the ALERTEX PC app. From the app, the ALERTEX system can be monitored, activated, and tested. Additionally, email alerts can be set up to be sent to 3 separate email groups in the event of an activation. 

The ALERTEX Wireless Critical Alert System comprises two main variants: ALERTEX Fire Alert and ALERTEX Lockdown.

The ALERTEX Fire Alert system is ideal for temporary or evolving sites, i.e. construction and utility sites, that require a robust alert to fire. As it is fully portable and wire-free, it can be installed quickly and simply without the need for civil works.

ALERTEX Fire Alert units comply with current HSE Fire Safety Guidelines (HSG168) regarding audible and visual alerts to fire on construction sites. 

The ALERTEX 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.

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’.
