Summary/ Overview


The shop monitor unit (MSU840) is designed to enable small units with conventional fire detection to be fully integrated with a main intelligent addressable fire system.

Product Description/ Features/ Specifications


An extensive range of interfaces are available to support the Cooper range of control panels, providing solutions for most design requirements.

The shop monitor unit (MSU840) is designed to enable small units with conventional fire detection to be fully integrated with a main intelligent addressable fire system.

This unit is ideal for applications such as connecting individual shop units into a main shopping centre system.

An external power supply is required to drive the 2 conventional sounder circuits. This power supply must be regulated for fire and current limited.

Features

  • Soft addressed
  • Integral short circuit isolator
  • Single address
  • Provides 2 conventional sounder circuits
  • Accepts a zone of Cooper conventional detectors and a zone of conventional callpoints
  • Includes output changeover contacts (fire relay)
  • Inputs monitored for open, short circuits and earth contact faults

Benefits

  • Quick and simple to install
  • No hard addressing required (Plug and play)
  • Easy to expand a system using existing wiring
  • Reduced installation cost by using the 2 sounder circuits
