4 zones extinguishant control panel for gas extinguishing system fire suppression panel FM200

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 electrical

automatic 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.
