Intelligent Input Module 952E

I. Overview

The 952E Intelligent input module (952E module for short) isused with MN300,a two-bus fire alarm control panel. It can be connected with a conventionalsmoke detector, a conventional heat detector, a conventional manual call point,a conventional hooter/horn and some other equipment. After the said equipmentstarts to operate, the alarm signal output will be sent by the CFT-952 moduleto the fire alarm control panel through a signal bus to give a fire alarm.
