A1446 Addressable Loop Interfaces

| Печать |


A1446

  • Ideal for use with all Control Equipment's Apollo protocol analogue addressable control panels
  • 3 inputs, prioritised in the protocol
  • 1 two-stage programmable alarm circuit rated 1 Amp @ 24V DC
  • 1 programmable relay rated 1 Amp @ 24V DC
  • Loop terminals with test probe locator
  • Normally Open or Normally Closed input selection
  • Selectable type code options
  • The A1447 Zone Module Adaptor board fits to the motherboard to change two of the inputs to fully monitored circuits
  • The highest quality of design, componentry and manufacture for outstanding durability
  • Uses the latest manufacturing technology to ensure consistency and reliability of product supply

Introduction

The Control Equipment range of loop interfaces are designed to allow remote monitoring of 3 voltage free contacts via the loop and communicate their status to the panel using analogue values.

The A1446 Sounder Controller Interface has a single change-over relay and fullymonitored sounder output circuit which can operate in pulsed or continuous mode. It requires a 24V DC supply.
