PAS were awarded the contract to supply and install a site wide public address and class change system for a new primary school located just several hundred metres from our offices. Partnering with one of the region's busiest electrical contractors, we supplied a discrete and effective communication system throughout the buildings to classrooms, circulation areas, halls and external areas. The system signals class change signals with pleasant electronic tones triggered by a programmable timer. Our engineers worked alongside the other contractors to deliver the system on time without any problems.
