The EIA-485 circuit is connected between the ACS EIA-485 connector
(TB6) on the main circuit board to terminal TB2 on the annunciator (see
Figure 5 on page 25).

Providing Power to Annunciators
The MS-9600’s 24 VDC main power supply is contained on its main circuit
board. No more than 3 Amps current can be drawn from these terminals in
standby or alarm. This 24 VDC output is filtered, regulated, power-limited,
and non-resettable.
The power run to the annunciator need not require a Power Supervision Relay
because loss of power is inherently supervised through a communication
loss.
Note: When not using the trouble input on annunciator or expander, jumper Trouble
Input terminals of TB1 on annunciator together.
The power circuit is connected between terminal TB3 on the MS-9600 and
terminal TB1 on the annunciator (see Figure 6 on page 26) as shown below.
