2.5 - Connecting Speaker/Amplifiers
The Millennium System Master is capable of driving a total of 200
(64 of which can be addressable) 5532M Series speaker/amplifiers.
Connect the console to the speaker/amplifiers as described below
(See Figures 3 and 7).
1. Connect 10V RMS audio line (or 5V RMS for live voice
evacuation) from "Main Out" (terminal block TB10) to the first
5532M speaker/amplifier. For connections to the 5532M
speaker/amplifier, refer to the instructions supplied with the
unit.
2. Continue to connect remaining 5532M series speaker/
amplifiers as shown in Figure 7 ending the loop with a 2.2K
end-of-line resistor (Part Number EOL-2.2).
3. For 5532M-485 Series speaker/amplifiers, connect the RS485
wire from +TX/RX (TB10) on the console board to terminal
+TX/RX on the RS485 COMM board. Connect the RS485 wire
from -TX/RX (TB10) on the console board to -TX/RX on the
RS485 COMM board. For further installation details for 5532M-
485 series, refer to installation instructions P/N 3100345.
2.6 - Connecting External Initiating Inputs
The initiating contacts operate on a pyramid-type priority system.
Output from a contact closure on Input 1 overrides the output from
a contact closure on Inputs 2, 3 and 4. The output from a contact
closure on Input 2 overrides the output from a contact closure on
Inputs 3 and 4. Likewise, the output from a contact closure on
Input 3 overrides the output from a contact closure on Input 4. The
output from a contact closure on Input 4 cannot override the out-
put from any other external input.
1. Remove all test resistors from the input terminals. Install 4.7K
ohm resistors, Cat. No. EOL-4.7, on terminals that will not have
initiating contacts connected to them.
2. Connect normally-open initiating contact(s) to input terminals
IN1, IN2, IN3, IN4 on External Input terminal block, TB14 (see
Figures 3 and 8) as required. Install 4.7K ohm resistors, Cat.
No. EOL 4-7, at the end of each circuit as shown in Figure 8.
NOTE: If connecting an external input to a Fire Alarm Panel, refer to
Section 2.8.
