A1445

  • Ideal for use with all Control Equipment's Apollo protocol analogue addressable control panels
  • 3 inputs, prioritised in the protocol
  • 3 independently programmable relay outputs rated 8 Amps @ 30V 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 A1445 Relay Interface has 3 single pole change-over relay outputs and requires a 24V DC supply.

The A1445 can also be used as a zone monitor interfaces with the addition of the A1447 Zone Monitor Unit. This unit plugs onto the A1445 and provides monitoring on Inputs 1 & 2 for fire, fault and quiescent conditions, with Input 3 operating as an auxiliary fault input. The A1445/47 can also be used to provide remote switch monitoring with fault detection if the inputs being monitored are remote from the interface.
