2 INTRODUCTION
The instructions given in this document are common to all the ‘MZX125
and MZX250’ fire controllers, any differences being outlined as
appropriate This document is written for Firmware Version 14.
The MINERVA MZX 125/250, form a comprehensive and compatible
range of modular and flexible EN54 approved addressable fire controllers
using Tyco MZX Technology
TM
.
Both variants fully comply with the requirements of EN54 parts 2 and 4 and
may be installed in a system which complies with the requirements of BS
5839 : Part 1.
