Expansion Power Supply (EPS) Installation Instructions
Panel interconnections
Use the following steps and the figure on the next page to
connect the EPS to the Main System Board (MSB).
1.
Remove AC and battery power from the panel.
You
will be wiring to the AC line.
Be sure the circuit
breaker is OFF and tagged.
2.
You have the option of removing the Depleted Battery
Cutout jumper (
R76
) on the EPS. Removing the
jumper has the following effects:
-
The system will NOT initiate an alarm if the first
alarm occurs after the depleted battery state has
been detected.
-
The system will shut down 60 seconds after the
depleted battery condition is detected.
Remove the jumper if required. Note that there is a
corresponding option in the programmer that must be
set; see the
Front Panel Installing, Operating, and
Programming Instructions
(579-704 for 4006,
579-716 for 4008).
3.
Connect the data flex harness (166-438) from
J1
on
the EPS to
-
J8
on the 4006-9801
-
J3
on the 4008-9801
4.
The AC harness (734-179) is used to connect AC
power from the MSB to the EPS.
-
AC source is 120 VAC, 60 Hz (single phase)
or
240 VAC (nominal), 50 Hz (single phase).
-
Strip 3/8" insulation from the black and white
wires.
-
Connect the black wire lead to the LEFT MSB
AC power terminal (
TB4
) marked “LINE.”
-
Connect the white wire lead to the RIGHT MSB
AC power terminal (
TB4
) marked “NEUTRAL.”
-
Connect the snap-on AC harness connector to
P6
on the EPS.
5.
Connect the battery harness (734-180) from
P3
on the
EPS to the battery connector on the MSB (
P13
on the
4006;
P14
on the 4008). Do not connect the harness to
the batteries until you are ready to power up the
system. Connectors should be aligned such that:
-
On P13 or P14 on the MSB, the red wire is on the
left and the black wire is on the right.
-
On P3 on the EPS, the red wire is on the bottom
and the black wire is on top (closer to R76; see
the figure on the next page).
