Ampac

Switch Monitor Plus

Product Overview

The Switch Monitor Plus with Isolator is designed to monitor the state of one or more single pole, volt free contacts connected on a single pair of cables and to report the status to Ampac compatible analogue control equipment. Additional circuitry is incorporated to monitor flow switches and provide a time delay. It can also be used to reset a beam detector.

Features

  • Output for resetting a remote detector
  • Four input states – ’normal’, ’fault’, ’pre-alarm’ and ’alarm’
  • Two visible LEDs
  • Selectable alarm delay for monitoring flow switches – 30 seconds
  • Built-in short circuit isolator
