WiLAS Installation & User Guide

The 

‘Wireless Alert Siren’ (WiLAS) System

 from EAS was developed to deliver louder, more easily 

distinguished “

Lockdown

” and “

Evacuation

” alerts, or other site-specific warnings, more rapidly and at a 

significantly lower installed cost, compared to traditional ‘hard-wired’ systems with central control panels. 

The 

WiLAS System

 is a completely wirelessly networked, wirelessly activated alert siren system, with 

optional supplementary visual warning devices. The total absence of cabling to distributed power and control 

signals around an installed network, means warning devices can be placed where they’re needed to deliver 

their warnings to best effect; and because the remote controls are also compact and wireless, they can be 

either carried in a pocket, or located at fixed locations anywhere around the site where 

WiLAS

 is installed. 

This not only dramatically improves design flexibility and dramatically lowers response times , it also 

removes inherent points of failure (such as centralised power and control  cables which, if damaged, could 

render the entire system useless) as well as lowers the costs of installation. Simply place the siren (or 

optional flashing beacons) where they’re needed around the workplace or site to be covered, place fixed 

(optional) activation panels where they’re needed, and distribute wireless handheld remote controls to 

authorised operators as required, to ensure optimal site coverage. 

Then, in an emergency - whether it be a lockdown condition due to an intruder on site, or an evacuation due 

to a fire or chemical spill – simply select the required alert tone on any of the handheld or fixed wireless 

controls, and within seconds, every siren and/or beacon is activated. Whether it’s one or one hundred 

sirens, or one building or a mine site covering several square kilometres, 

WiLAS

 improves site safety by 

delivering more easily understood warnings. 

Configuring a 

WiLAS System

 for your site is relatively easy. Sirens are placed to deliver best audio 

coverage, with each pair of sirens being connected to a Control Station that supplies power and provides the 

network connection. As long as any one Control Station is within 300-400 metres (maximum) of at least one 

Control Station (but preferably two or more), then any one Control Station that is activated by a wireless 

control will repeat the activation/deactivation signal to any other Control Station in range.  

In this way, even over areas of several square kilometres, signals can be rapidly repeated, setting off every 

siren or flashing beacon in the network - and all without the need for interconnecting cable around the site 

between control panels and sirens.
