A70E-2 Conventional Zone Interface Module
Installation Sheet
Description
The A70E-2 Conventional Zone Interface Module provides the
interface between a conventional zone of detectors and an
addressable loop. The zone of conventional detectors appears
as a single addressable device on the addressable loop.
The module includes the following features:
•
Red LED to indicate alarm condition
•
Yellow LED to indicate fault condition
•
DIN rail or surface mounting
•
24 V or loop powered
•
Built-in head-out operation
•
Drives intrinsically safe equipment
Installation
The A70E-2 contains no user-serviceable parts and should not
be disassembled.
To install the device:
1. Verify that all field wiring is free of open circuits, short
circuits, and ground faults.
2. Make wiring connections as shown in Figure 2 and
Figure 3.
A P15 or 35 mm DIN rail can be used. See Figure 1 for
mounting hole dimensions and locations. The mounting
hole diameters are 4 mm and centres are at 40.5 and
67.0 mm.
