A1446 Addressable Loop Interfaces
|
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.
