Installation Relays
28 MS-9600 PN 51335:E 7/9/03
2.3 Relays
The FACP provides two programmable Form-C relays and one fixed fail-safe Form-C
trouble relay, all with contacts rated for 2.0 amps @ 30 VDC (resistive) or 0.5 amps @
30 VAC (resistive). The Alarm and Supervisory silk-screen labels reflect the factory
default programming for the two programmable relays.
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. Refer to UL Power-limited wiring requirements.
2.4 Notification Appliance Circuits
The control panel provides four Style Y/Class B or two Style Z/Class A NACs
(Notification Appliance Circuits). Each circuit is capable of 3.0 amps of current. Total
system current in alarm cannot exceed 7.0 amps (refer to "Calculating the System
Current Draw" on page 137). Use UL listed 24 VDC 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 NACs, which are
located on the main circuit board, may be expanded via the Fire•Lite FCPS Series field
charger/power supplies.
The following sections describe the configuration and wiring of Style Y and Style Z
Notification Appliance Circuits on the MS-9600 main circuit board. The NACs are
configured for Style Y (Class B) from the factory. Refer to "Configuring NACs" on
page 29 for information on changing the NAC configuration to Style Z (Class A) and
preparing the NACKEY configuration card located in JP8, when installing a 4XTMF
Transmitter Module.

Note that the relays labeled as Alarm
Relay (Relay 1) and Supervisory Relay
(Relay 3) reflect the factory default
programming for these relays which are
programmable.
The relay labeled Trouble Relay (Relay 2)
is fixed and cannot be changed. It is a fail-
safe relay which will transfer on any
trouble or total power failure.
