A Red Portable Site Alarm (PSA) is positioned behind the works access with optional camera facing towards it. Traffic Management Operatives (TMO) are issued with a wearable trigger that can be used to activate the Incursion Warning System.
In case of an errant or emergency vehicle incursion via the works access, the TMO simply presses their Safelane trigger, which will activate the Red PSA positioned behind them. This will activate its sirens and optional camera whilst at the same time activating Blue PSA’s positioned near the workforce. There is no limitation in distance between PSAs and no limitation in how many can be used. For example, in case there are two works access points and three works areas, the suggested deployment would require two Red PSAs and three Blue PSAs.
