NODE

The NODE allows expansion of the JUNO NET system in groups of 1 to 4 loops.

It can be supplied as a standalone unit or in an enclosed cabinet, which contains a 2,3 A PSU/ Charger unit and space for standby rechargeable batteries. One RS422/RS485, fibre optic or TCP/IP interface is required per cabinet to enable networking with the rest of the system.

Each NODE mainboard controls up to four analogue addressable detection loops via its own independent processor. In the event of communication failure with the main control unit, the NODE can operate independently, detecting Fire/Fault events and activating connected sounders and internal relays.
