Cosine Developments Products

All products are designed to meet the stringent South African Bureau of Standards (otherwise known as SABS) requirements in terms of performance, reliability and safety (SABS Standards are based on international IEC Standards). 

Occupancy Sensor Range

With highly customizable settings, the Cosine Developments occupancy sensors are the number one on the market. The benefits of an occupancy sensor? Simple energy saving solution. When the room is vacant the lights will turn off – the duration times, sensitivities may all be altered but the general concept remains the same.

Energy Saving HVAC

Normal occupancy sensors only switch the lights off, leaving the air-conditioner running. The HVAC facilitates the switching of both lighting and HVAC circuits greatly increasing energy saving.

Emergency Lighting

Emergency lighting is compulsory in any area where a mains failure could leave either the public or workers in darkness (OHS Act 85 of 1993). Furthermore, installed emergency lighting must comply with strict compulsory performance standards (VC 8055). The performance standard is defined by SANS 1464 part 22. Failure to comply can result in fines and/or legal action.
