ADM800 - Overview

The ADM800 displays comprehensive information about the AGM300 network status and enables complete programming control of all system operations. The prominent features of the display module are discussed below.

Display Screen

The display screen is a back-lit LCD.

Control Keys

The 4 keys on each side of the display window are used to navigate between screen displays. A graphic box that is open to the edge of the window indicates that the adjacent control key is active. The 3 keys along the bottom of the window are also used to navigate between screens. A text block directly above the key indicates that the key is active. An active key can be used to navigate to another screen. A graphic box, that is not open to the edge, displays information only and the adjacent control key is inactive.

Cursor Key-Pad

The cursor key-pad is used to move about screens, enter setup information and choose between setup parameters. When entering information the LEFT/RIGHT keys move the cursor across an entry field, while the UP/DOWN keys scroll data entry options. The ENTER key is used to accept data entries.

LED Indicators

The three LED indicators provide an overview of network status.

GREEN

Glows when the system is operational.

RED

Glows when the ADM800 detects a leak, spill, or evacuate alarm

 

condition anywhere on the network.

YELLOW

Glows when the ADM800 detects a system fault anywhere on the network.

Internal Audible Alarm

An internal audible alarm is provided that can be programmed to sound when there is an occurrence of the selected condition (refer to Audible Alarm on Page 35).

External Alarms

Additionally, 2 SPDT alarm contacts are provided for the connection of external alarm devices. These alarms are useful for alerting the user to global conditions anywhere on the network. Each relay can be programmed to respond to alarm, fault, or monitor ON conditions (refer to Setting Relay Parameters on Page 36).
