Section 9. FINAL POWER UP

This section provides the following information:
• Connecting the AC transformer
• Making earth ground connections
• Applying power to the control
• Installing the backup battery
• Backup battery calculations
In Section 2, you made temporary power connections for the purpose of
programming and testing the installation. This section provides information
about final power-up procedures and battery size calculations.

AC Power Connections

The 5110XM has a built-in, enclosed AC power transformer with manually
resettable circuit breaker protection, located in the lower lefthand corner of the
control's cabinet.
1. A dedicated 120VAC circuit must be used for fire applications.
U L
2. Wires must be rated for 90 degrees C or higher operation.
Follow the steps below to make AC power connections.
1. Remove the cover from the transformer's enclosure.
2. Remove the lower knockout on the lefthand side of the cabinet. Run 120VAC
power wires into the transformer enclosure via this knockout.
Make sure that the dedicated AC circuit is not powered at this
time. Apply AC power only after all other wiring, except the backup battery
wiring, has been completed.
3. Use wire nuts (not supplied) to splice the 120VAC wires to the transformer's
black and white flying leads.
transformer enclosure.
4. Connect the transformer's 18VAC BLUE flying leads which emerge from the
top of the enclosure to the 5110XM's AC terminals (Terminals 1 and 2).
5. Make earth ground connections as specified below.
Earth Ground Connections
The 5110XM requires connection to a good earth ground in order to provide
proper 120VAC shock hazard protection, lightening transient protection, and
earth ground fault detection.
Refer to the National Electrical Code for proper earth grounding methods.
To make earth ground connections, do the following:
1. Run an earth ground wire into the transformer enclosure via the same
knockout used for 120VAC wiring.
Push the mated wires back into the
