The NOTIFIER NFS2-640 KDM-2 Digital Metronome is designed to meet stringent safety and installation standards, ensuring reliable performance in fire alarm systems. Wiring methods for this device must comply with UL 681 for burglar and holdup alarm systems as well as UL 827 for central station alarm services, guaranteeing secure and consistent connections.
When installing the CPU Board NOTIFIER NFS2-640 KDM-2, it is important to mount its backbox in a dry, indoor location. The recommended environmental conditions include a normal room temperature between 15-27°C (60-80°F) and a relative humidity of 93% ± 2% at 32°C (90°F), ensuring optimal operation and longevity.
The backbox of the NOTIFIER NFS2-640 KDM-2 Korg Digital Metronome KDM2 should be positioned so that its top edge is approximately 66 inches (1.6764 meters) above the finished floor surface. This placement facilitates easy access while complying with NFPA 90 article 110.33 requirements for cabinet accessibility.
Additionally, sufficient clearance must be provided around the Digital Metronome NOTIFIER NFS2-640 KDM-2 cabinet to allow the door to swing freely without obstruction. These guidelines help maintain safety, accessibility, and effective fire alarm system performance in various building environments.
