Providing Power To Annunciators - Fire-Lite ACM-16ATF Instruction Manual

Appendix C: MS-9200
The EIA-485 circuit is connected between the ACS Mode connector (TB5)
on the main circuit board to terminal TB2 on the annunciator (see Figure 5
on page 25).

Providing Power to Annunciators

The MS-9200's 24 VDC main power supply is contained on its main circuit
board. No more than 300 mA 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 TB4 on the MS-9200 and
terminal TB1 on the annunciator (see Figure 6 on page 26) as shown below.
