4.13.7 NOTIFICATION APPLIANCE CIRCUIT WIRING (P8 & P9 )
P8 and P9 are two separate notification appliance circuits (NAC’s) that provide the ability to activate
compatible, UL-listed notification appliances listed in Fike document 06-186, “Device Compatibility manual”.
The NAC circuits are supervised, power-limited, and can be wired Class B (using 1.2K EOL) or Class A (no
EOL), as shown in Exhibits 4-21 and 4-22. Shielded wiring is not required, however if used, land at the panel
terminal block and pass through at each device similar to SLC device wiring.
The NACs can be configured to initiate the Gentex Commander Series or System Sensor SpectrAlert Series
sync protocol. This allows all devices (strobes and horns) connected to the circuit to operate in unison. It
also allows the audible devices to be silenced while the visual signals remain operational or silence both
audible and visual devices. This is accomplished without requiring purchase and installation of a separate
sync module. Both circuits must be programmed to use the same manufacturers sync pulse if this option is
used.
4.14 INITIAL POWER-UP WITH FIELD WIRING CONNECTED
1. Energize AC power to Cheetah Xi 50 controller and field power supplies (if installed) with field wiring
connected.
2. Connect batteries to the Cheetah Xi 50 controller and field power supplies (if installed).
3. Validate that all devices begin to function appropriately and wiring is connected properly.
4. Correct all circuit faults.
I
Caution
Immediately power down the system (DC followed by AC) if
the display shows improper characters, you smell smoke, or if
you see sparks. Each of these conditions indicates improper
connections or malfunction of components. After power is
removed, investigate for source of malfunction by checking
module connections in the area of the malfunction.
