General Notes:
• Refer to the Notifier Device Compatibility Document for a list of Notification Appliance Circuits and Releasing Circuits. Refer to Section 6,
"Compatible Equipment", on page 67 for SLC devices that are compatible with the NFS2-3030.
• Refer to the Section 6, "Compatible Equipment" for a list of external accessories that are compatible with the NFS2-3030.
• SLC connection provided through the LCM-320/LEM-320. Refer to page 5 for wiring the SLC and the Notifier SLC Wiring Manual for
additional information.
• For NAC applications: NAC support provided via the FCPS-24S6/S8 or the ACPS-610. Refer to documents provided with these products for
NAC application information.
• For Releasing Applications:
The AMPS-24 can provide up to 3A for releasing applications, limited by the FCM-1-REL.
The APS2-6R can provide up to 6A for releasing applications, limited by the FCM-1-REL.

1.1.2 Memory-Backup Battery

The lithium battery on the CPU provides backup of the CPU's on-board memory during
power loss.
The CPU ships with an insulator to prevent its lithium battery from discharging. To preserve
the battery, this insulator should be left in place as long as possible before applying AC
power. Some installers may find it convenient to remove the insulator before mounting all
equipment.
If the insulator is not removed before applying AC power, a trouble will be displayed on the
control panel.
To replace the battery:
1. Make a full backup of all system settings to prevent loss of programming data.
2. Disconnect all power sources.
3. CPU2-3030D only: Disconnect wiring and remove CPU2-3030D from backbox (3 screws at the top, lift board and tabs out of slot) and remove
keypad.
4. Remove battery from under the clip.(use fingers, tools could damage components)
5. CPU2-3030D only: replace keyboard, reinstall CPU2-3030D into chassis and reconnect wiring.
6. Power up the system.
7. Dispose of the used battery promptly. Keep away from children. Do not disassemble and do not dispose of in fire.
WARNING: RISK OF FIRE AND BURNS
!
THE BATTERY USED IN THIS DEVICE MAY PRESENT A RISK OF FIRE OR CHEMICAL BURN IF MISTREATED. DO NOT
RECHARGE, DISASSEMBLE, HEAT ABOVE 212°F (100°C) OR INCINERATE. REPLACE BATTERY WITH RAYOVAC
LITHIUM 3 VOLT BR2335 OR EQUIVALENT ONLY. USE OF ANOTHER BATTERY MAY PRESENT A RISK OF FIRE OR
EXPLOSION.

• Illuminates when AC power is within normal operating limits
• Illuminates when at least one fire alarm event exists. It will flash if any of these events are
unacknowledged.
• This LED is for factory use only
• Illuminates if there is an abnormal hardware or software condition. Contact technical support.
The panel is out of service when this LED is illuminated or flashing
• Illuminates when at least one trouble event exists. It will flash if any of these events are
unacknowledged
• Illuminates when at least one security event exists. It will flash if any of these events are
unacknowledged
• Illuminates when at least one pre-alarm event exists. It will flash if any of these events are
unacknowledged
• Illuminates when at least one supervisory event exists. It will flash if any of these events are
unacknowledged
• Illuminates if the NFS2-3030 Notification Appliances have been silenced. If flashes is some
but not all the NFS2-3030 NACs have been silenced
• Illuminates when at least one device has been disabled. It will flash until all disabled points
have been acknowledged
• Illuminates for MNS alarms, process monitor, CO alarm, CO pre-alarm, hazard alert or
weather alert. It will flash if any of these events are unacknowledged
• On keypad only. Illuminates when the panel assumes control of local operation as primary
display. For MN applications, will illuminate when controls are available
