AIM-2SL Start up LED Function

After the logic test, the LED test will test all LEDs for proper operation:

1. All LEDs ON Green, .5 second (Including ON LINE LEDs)

2. All LEDs ON Orange, .5 second

3. All LEDs ON Red, .5 second

4. Buzzer ON for .5 second and HOST LED ON for 1 second.

2.2.2 Normal Operation

After initialization and self tests, the LEDs will switch to normal operation and will display

information about the panel operation.

A single tri-color LED per zone indicates Red for Alarm, Orange for Trouble, and Green for

Non-alarm. The LEDs are organized as 4 columns (A,B,C,D,) of 19 each. The LEDs of rows 1-18

are tri-color to display alarm/reader status. LEDs of row 19 (ONLINE) are Green, and show

general panel status. Name plate inserts are provided adjacent to each LED column for user

defined text to describe LED function (See Figure 61).

2.2.3 Host LED

The Green HOST LED indicates the status of communication between the ASA-72 and host (see

Figure 55). The HOST LED functions in two modes: NORMAL mode and TEST mode.

In NORMAL mode, the LED has four states. The four states and the LED activity are shown

below:

In TEST mode, the LED shows the communication activity. TEST mode is entered by depressing

and holding down the TEST push button. When the TEST button is detected as depressed, the

HOST LED will turn on for 1 second to fulfill the LED test function, then, the HOST LED will follow

the host communication activity. TEST mode is exited when the test button is released.
