Genesis PIR detectors comply with new NSI Code of Practice for scaffold alarm systems

Luminite is pleased to confirm its wireless Genesis PIR detector systems comply with the product performance requirements of the new NSI Code of Practice for scaffold alarm systems (NCP 115).

Introduced in January to raise standards and avoid malpractice in the scaffold industry, the code of practice covers the design, installation, commissioning and maintenance of scaffolding alarm systems (SAS). NSI NACOSS Gold and System Silver installers must all comply.

Graham Creek, managing director of the UK-based PIR manufacturer Luminite, explains the significance of the code of practice. “NSI members make up many of the UK’s leading installation companies. They are regularly inspected to ensure they meet the high standards of installation the NSI demands. From January, Gold and System Silver installers are obliged to comply with NCP 115 to retain their NSI status.”

NCP 115 covers two levels of Scaffold Alarm System where PIRs are used. A standalone “Basic” system, with an audible alarm, and an “Enhanced” system which links to a BS 5979 compliant remote monitoring station or ARC, for off-site surveillance. Many PIRs simply do not have the required functionality to enable system compliance.

Graham again, “At Luminite, we welcome the new product performance requirements. The detection range of PIRs must have limit adjustments to avoid detection overspill. Our Genesis PIRs adjust in this way and, in addition, we provide a walk test instrument to verify the exact detection extents. Wireless systems must now meet relevant statutory regulations for communications, in our case RF. In a power “out” situation, the new code states the system must operate for a minimum of 12 hours. Ours is 2 years, so definitely compliant! An expensive battery back-up or uninterrupted power supply solution would be needed with many other systems. Remote set and un-set are also essential and the product housing must meet EN60529 IP54 or IP65 requirements.

“An extremely significant aspect of performance requirements is that the PIRs must distinguish between intrusion, tamper and fault signals, not combining them into one alarm. We designed Genesis PIRs to do this, so that installers were able to maintain systems more easily and reduce false alarms. Tamper and fault signals must be recognised within 10 seconds and intrusion signals must activate almost immediately. System access and the authorisation level for different users is also required.”
