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 2-4
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.

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-24FE Field
Charger/Power Supply. Surge protection for notification appliances may be provided by using one of the UL listed
compatible surge suppressors listed in the Fire•Lite Device Compatibility Document.
