2. Use a wire nut (not supplied) to splice this earth ground wire to the green

flying lead located inside of and bonded to the transformer enclosure. Push

3. Connect the green flying lead which emerges from the top of the transformer

enclosure to the 5110XM's earth ground terminal (Terminal 8).

4. Replace the transformer enclosure cover after wiring is complete.

Powering Up the System

Apply AC power to the control. Following power-up, Busy-Standby (alpha

keypads) or NOT READY (fixed-word keypads) will be displayed.

After approximately 1 minute, the initial displays will revert to SYSTEM

NORMAL for alpha keypads, or AC for fixed-word keypads (if there are no

faulted zones).

To bypass this delay, press: [#] + [0].

Connecting The Back-Up Battery

In the event of an AC power loss, the control must be supported by a back-up,

rechargeable 12V, 7AH min/14AH max sealed lead acid (gel cell type) battery.

The battery's capacity must be sized to provide 24 hours (UL Central Station

Fire) or 60 hours (UL Remote Station Fire) of standby time followed by 5

minutes of alarm time. Use the steps below to calculate the required battery

capacity.

Calculating the Battery Size Needed

Use the worksheets below to determine the total standby and alarm loads and

the required battery capacity. Then select a battery having a capacity greater

than or equal to the calculated capacity.
