众安科外销热款 4回路气体灭火控制器 自动灭火消防系统  气体灭火主机  Fire Extinguishant Control Panel /Suppression Panel 

1. Introduction

The automatic extinguisher control panel is designed in accordance with European standards EN54-2 and EN54-4 Fire Detection and Fire Alarm systems - Control and Indicating Equipment and EN12094-1 Fixed firefighting systems - Components for gas extinguishing systems - Part 1: Requirements and test methods for electricalautomatic control and delay devices.

The control equipment is a combined fire alarm control panel and extinguishing system and has four detection zones, any or all of which are capable of contributing to the extinguishant release decision.Control panels have an integral, mains powered battery charger and power supply designed in accordance with the requirements of EN54-4.
