Multiplexer Module - BeaconMedaes TotalAlert 2 Installation, Operation And Maintenance Instructions

Multiplexer Module

Press and hold the front panel TEST but-
ton for 5 s to initiate the following
sequence:
• Audible alarm sounds for 1 s.
• Each green LED is displayed in
sequence for 0.5 s.
• Each red LED is displayed in sequence
for 0.5 s.
• Software revision is displayed as
follows:
- Expressed as a three digit number
(e.g. 1.0.2).
- Each digit of number is displayed
separately for 2 s and separated
from the next digit by a 1 s flashing
of all indicators.
- Each number is displayed in a
binary code where each LED
indicator has a binary value
(Figure 109.).
- Example: Software revision 1.0.2
would be displayed as follows:
• First digit is determined by 2 s
illumination of top left LED (bit 0
= number 1).
• All LEDs illuminate for 1 s.
• Second digit is determined to be
0 because no LEDs are
illuminated for 2 s.
• All LEDs illuminate for 1 s.
• Third digit of is determined by 2
s illumination of 2nd red LED (Bit
1 = number 2).
• After all three digits of software revision
have been displayed, all LEDs
illuminate for 1 s before displaying the
module's network address.
