ПРИБОР ПРИЕМНО-КОНТРОЛЬНЫЙ ПОЖАРНЫЙ АДРЕСНО-АНАЛОГОВЫЙ NEXUS

TECHNICAL DESCRIPTION

The nexus analogue addressable panel is available as a 1-8 loop panel using plug-in loop driver cards. Each loop is rated at 200mA and will control up to 126 Apollo XP95 devices. All addresses may be configured as cause/effect outputs, with up to 255 different programmable groups and 3 independently programmable output bits per address. Panels are housed in well-designed enclosures and are finished in a hard-wearing epoxy paint.

The motherboard electronics are fixed to a detachable chassis thus facilitating a completely empty enclosure for first fix installation. Top entry plastic grommets, bottom/rear entry plastic grommets (for mains) and rear entry knockouts are designed to assist with cable installation.

The nexus has a 4 line x 20 character backlit LCD display, showing device address, zone, type, status and location text. The LCD display is also used as a menu-driven engineers' configuration display. User controls are accessed by means of keyswitch enabled membrane controls with password protection for engineering purposes.

64 zonal LEDs and 'plug-in' printer are available as options.

The panel provides 2 common fire changeover relays and 1 common fault changeover relay, each rated at 1A, 30V DC. Six normally open inputs provide for remote silence, reset system, evacuate, silence fault buzzer, class change and remote fault input.

The nexus panel may control up to 13 additional duplicate displays, with full user and engineer capability via RS485 data comms (24V DC power also required). Up to 31 x 8-way programmable panel expansion boards may be connected to the panel via an RS485 I/O data link (24V DC power also required). Each 8-way board may provide either 8 programmable open inputs and 8 programmable relays or 8 programmable open inputs and 8 programmable two-stage alarm circuits.

Extensive panel and network cause/effect programming is achieved via the PC programming package.

Full networking with other nexus panels, konex network repeaters and graphics package may be achieved with an additional plug-in network driver card. Network cause/effect may be programmed between nexus panels and active konex network repeaters.
