The WES3 Radio Repeater Link unit is essentially very simple - it extends / boosts the range of your WES system on very large, complicated or high density construction sites.
Do I need a link? In most cases, you’ll probably never need a radio repeater unit for your WES3 system – each unit has excellent wireless range already that will cover most large structures. However, if you do receive a low signal warning, for example if a far-off fire point becomes more obscured as a build progresses and starts to lose signal, you can add a Link unit to boost the signal and make sure your fire alarm system continues to work optimally.
