Description/Application

The Controller, BC-420. serves as a connection unit for

the detection loop, alarm sounders, controls and inputs.

It can accommodate up to a maximum of 12 modules.

The system offers a Loop Driver Module for detection

loops and several types of I/O modules (see Optional

Modules below).

There can be a maximum of 6 Loop Driver Modules

connected to each Controller. All modules are easily

plugged onto each other on a standard mounting rail

inside the unit.

The Controller provides connections for 2 Ethernet ports

and 2 USB host ports.

The Controller communicates with other system units on

the Ethernet-based local area network, AutroNet.
