Ziton ZP3-MB2C-230V-2L 2-loop Motherboard on Chassis

Overview

The Ziton ZP3-MB2C-230V-2L is a 2-loop main motherboard assembly for Ziton ZP3 analogue addressable fire alarm control panel. The Ziton ZP3-MB2C-230V-2L works together with the ZP3-CPU1 processor board to provide two independent fire detection loops, each loop supports up to 127 addressable fire devices including smoke detectors, heat detectors, manual call points and interface modules. The suffix 230V indicates the unit is designed for 230V AC mains supply, and 2L stands for two loops. The Ziton ZP3-MB2C-230V-2L is widely stocked as spare chassis motherboard for maintenance of commercial, industrial and marine ZP3 fire alarm systems.

Features

The Ziton ZP3-MB2C-230V-2L supports dual isolated SLC loops with short-circuit and open-circuit monitoring. It carries integrated power regulation circuit and loop driver circuit, complying with EN 54-2 and EN 54-4 fire alarm standards. The Ziton ZP3-MB2C-230V-2L supports hot swap of CPU and loop interface components during panel shutdown, and works with Ziton Planner software for site configuration, device mapping and firmware upgrade. The Ziton ZP3-MB2C-230V-2L has built-in hardware fault diagnosis, reporting loop failure, earth fault and power supply abnormality to the panel CPU. Matching variants include 1-loop MB2C-230V-1L and 4-loop MB2C-230V-4L for different scale fire systems.

Specs

Device Type: 2-loop chassis motherboard assembly Model: Ziton ZP3-MB2C-230V-2L Applicable System: ZP3 analogue addressable fire alarm panel Loop Quantity: 2 SLC detection loops Max Devices per Loop: 127 addressable units Mains Supply: 230V AC Certification: EN 54-2, EN 54-4 Configuration Software: Ziton Planner Mounting: Built-in chassis assembly inside ZP3 cabinet Protection Grade: IP30 inside cabinet Application: Commercial building, water treatment plant, marine vessel, industrial fire alarm control panel

Principle

The Ziton ZP3-MB2C-230V-2L supplies power and communication signal to each detection loop. It polls addressable fire devices cyclically, receives detector analogue values and status feedback, then transmits all data to the ZP3 CPU board. When smoke, heat or manual alarm is triggered, the motherboard transmits alarm signal to the processor to activate sounder outputs, relay controls and local indication. The Ziton ZP3-MB2C-230V-2L continuously monitors loop integrity and triggers trouble signal when wiring fault occurs.

Applications

The Ziton ZP3-MB2C-230V-2L is used as core loop backplane assembly for Ziton ZP3 fire alarm control panels in factory, hotel, shipboard and public building fire safety systems. It serves two independent detection zones for medium-sized fire monitoring projects. The Ziton ZP3-MB2C-230V-2L applies to spare stock and emergency replacement of legacy ZP3 fire panel chassis assemblies. It also supports fire alarm panel renovation and loop expansion transformation.
