SPERA Analog Addressable Fire Alarm System

Description

NFU-7000-L

Nittan’s SPERA NFU-7000 Series Network 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 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 number allocation.
In addition the base panel includes 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.
NFU-7000 panel can see other panels’ condition of the same network. Each panel can be configured using standard NFU-7000 components.
The network interface module allows the panels to communicate on a peer-to-peer network via an industry standard ARCnet protocol. The network capabilities allow site specific customization and the ability to meet local and national requirements.
