Overview

PLEASE NOTE THAT THIS PRODUCT HAS BEEN DISCONTINUED.

The Noby-420 2-Zone Fire Panel has been designed to allow for an easier, yet more professional installation, while providing features that make the panel ideal for most installations.

The main control unit comes in an attractive metal cabinet with ample entries and connection space, while wiring is simplified by the provision of a sounder circuit for every zone. Built-in head removal monitoring, optional non latch zones, class change input and 24V auxiliary supply make the system as versatile as it is reliable.

Engineers have access to an 15 event fire memory which provides information on the most recent fire events. Engineers are further assisted by individual sounder circuit fault identification and sounder circuit isolation.
