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).
• 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. Splice one end of a 3-conductor cable
to the wire ends of the SA4120XM-1
Cable.
2. Connect the SA4120XM-1 cable plug
to the 8-pin connector on the control
(see the Summary of Connections
diagram for location of the 8-pin
connector).
3. Connect the other end of the
3-conductor cable to the 1361X10
Transformer, as shown in Figure 4.
Canadian Installations: See
Powerline Carrier Device section for
connections to the PSC04 X-10 Interface
and trigger pins.
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.
U L
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.
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.
