Connect the 1321 Transformer (1321CN in Canada) to terminals 1 and 2 on the control board. See Wire Run Chart for wire size to use.

•Use caution when wiring the transformer to the control to guard against blowing the transformer fuse (the fuse is non-replaceable).

AC AC

•Wiring to the AC transformer must not exceed 250 feet using 16 gauge wire. The voltage reading between terminals 1 and 2 of the control must not fall below 16.5VAC or an “AC LOSS” message will be displayed.

•Do not plug the transformer into the AC outlet until all wiring connections to the control are complete. As a safety precaution, always power down the control when making such connections.

1.Place the 12-volt backup battery in the cabinet.

2.After all connections to the control are completed and AC power has been applied, connect the red and black flying leads on the control board to the battery. Do not attach these leads to the battery terminals until all connections are completed.

UL For UL installations and Residential fire installations, refer to the chart on page 2-2 at left for the correct battery size required to meet the mandatory standby time.

Battery Saver Feature

Earth Ground

The battery will disconnect from the system after its voltage decreases below 9VDC. This assists the control panel in recharging the battery when AC is restored. IMPORTANT: The panel will not power up initially on battery power only. You must plug the transformer in first, and then connect the battery.

• This product has been designed and laboratory-tested to ensure its resistance to

damage from generally expected levels of lightning and electrical discharge, and does

not normally require an earth ground.

• If an earth ground is desired for additional protection in areas of severe electrical

activity, terminal 25 on the control board, or the cabinet, may be used as the ground

connection point. The following are examples of good earth grounds available at most

installations.

Metal Cold Water Pipe: Use a non-corrosive metal strap (copper is recommended) firmly secured to the pipe to which the ground lead is electrically connected and secured.

AC Power Outlet Ground: Available from 3-prong, 120VAC power outlets only. To test the integrity of the ground terminal, use a 3-wire circuit tester with neon lamp indicators, such as the UL Listed Ideal Model 61-035, or equivalent, available at most electrical supply stores.
