SPERA Analog Addressable Fire Alarm System


Nittan’s UL listed SPERA Series Fire Alarm Control Panels offer modular components for a network system providing a wide variety of applications. Designed for peer-to-peer network communications, the NFU-7000 allows for a maximum of 63 network nodes, while providing reliability, flexibility and expandability.

The NFU-7000 EV protocol is based on the platform which acquired reliabilities in European and Marin markets. Each base panel consists of one driver circuit board which is capable of driving 2 loops. A Nittan EV protocol supports 254 addresses. Owing to the contribution of expandability, addressable detectors and modules are available to be installed without constraint of address numbering. In addition the NFU-7000 equips Four Style Z/Y (Class A/B) Notification Appliance Circuits rated at 1.7 Amps each and a large 16 x 40 back-lit alphanumeric LCD display.
