8.2 Inputs
The Audio Line Splitter has the following inputs:
Input Description
IN1 - IN4
(TB1)
These inputs are used to manually active the applicable Zones 1-4 when using 3
rd
party paging
consoles. (See DIP switch setting 8.5 below)
Active low input. Short to 0V to activate (non-latching).
100V in
BRD60AMP
(TB3)
Version 3 Splitter (BRD60LMU3)
For the 25W, 50W or 120W amplifiers 100V line out then EOL K2 link must be fitted to last
splitter.
For the Tone generators on 250 and 500W 100V line out then do not fit EOL K2 link.
Version 2 Splitter (BRD60LMU2)
If the ASL is being connected to the 25W, 50W or 120W amplifiers, the 100V line out from the
Amplifier (25W & 50W) or Tone Generator (120W) is to be connected here.
100V in
From TXFR
(TB4)
Version 2 splitter boards (BRD60LMU2) Only
If the ASL is being connected to the 250W or 500W amplifiers, the 100V line out from the
amplifier is to be connected here
Note: When 3 or more (Max is 6) ASL board’s are used or the inputs are hardwired, the DIP
switch settings 0, 13, 14 and 15 are used to determine the operation of the ASL inputs (Refer to DIP switch
settings below).
8.3 Relay Output
The Audio Line Splitter has a single relay output:
Output Description
Fault Relay
(TB2)
Fault:
No Fault:
No Power:
Relay Open (De-energised)
Relay Closed (Energised)
Relay Open (De-Energised)
Note: When 3 or more ASL boards are used, the DIP switch settings 0, 13, 14 and 15 are used
to determine the operation of the ASL fault relay (Refer to DIP switch settings below).
8.4 Audio Line Outputs
The four split line outputs function as follows:
Zones 1-4
Provides 4 x 100VAC 100W maximum Audio Outputs.
Combined total of the four outputs should not exceed 250W.
Each output is monitored. EOL value is between 10K - 47kΩ 5% 1/3 Watt.
