Standard Relays
The MS-9200 provides a set of Form-C alarm and Form-C trouble contacts rated for 2.0 amps @ 30 VDC (resistive).
The panel also provides a Form-A supervisory contact rated for 2.0 amps @ 30 VDC (resistive). Refer to Figure 2-7
on page 27 for UL power-limited wiring requirements.
Note that relay connections may be power-limited or nonpower-limited, provided that 0.25" spacing is maintained
between conductors of power-limited and nonpower-limited circuits.
2.4
Notification Appliance Circuits
The MS-9200 provides two Notification Appliance (bell) Circuits configurable for Style Y or Style Z. Each circuit is
capable of 2.5 amps of current. Total current drawn from these as well as other DC power outputs cannot exceed 6.0
amps. Use UL listed 24 volt notification appliances only. Circuits are supervised and power-limited. Refer to the
Fire•Lite Device Compatibility Document for a listing of compatible notification appliances. The two NACs (Notifi-
cation Appliance Circuits) located on the main circuit board may be expanded via the Fire•Lite FCPS-24F/E Field
Charger/Power Supply.
2.5
Annunciator and PC/Printer Circuits
Connectors are provided for Terminal Mode and ACS Mode annunciators as well as a Personal Computer for
programming or a printer for hardcopy printouts of system information. Note that the TB7 Out and In polarities are
used for connection to a Terminal Mode annunciator. Refer to page 35 for information on PC/Printer wiring.

If using both power-limited and
nonpower-limited circuits,
leave one unused terminal
between power-limited and
nonpower-limited circuits.
Note: If relays are used as power-limited circuits,
paste supplied label to terminal block to indicate
use of power-limited wiring.
