Expansion Power Supply (EPS)
Installation Instructions
Introduction
The 4008/4006-9801 Expansion Power Supply (EPS) is an option module
that installs into the main fire alarm control panel. The EPS provides two
additional NACs, and filtered/regulated 24 VDC, alarm power.
The 3 A alarm power may be split between the two NACs and the
0.5 A auxiliary 24 VDC power tap. Refer to the NAC ratings section of these
instructions for circuit loading restrictions. The expansion power supply is
mounted to the right of the main system board (MSB) at the bottom of the
chassis, and is connected by the installer via three separate harnesses.
One EPS per system is allowed.
Figure 1, below, is an illustration of the EPS assembly.

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).

EOLR
SYSTEM
BOARD
• NAC wiring from the EPS is ro uted within th e
cabinet as shown above.
• NAC terminals accept 18 AWG to 12 AWG
wire. Larger wire reduces line loss and
allows longer wiring distance from the FACP
to the notification applia nces.
• Use a VOM to test conductors for grou nds
and stray voltages before connecti on to
appliances and panel.
• All wiring is supervised and Power Limited.
• Circuits must not be “T”-tapped.
• Terminate each Class B circuit with a
10 k, 0.5 W resistor (733-894). For Canadian
applications, mount the end-of-line resistor
to TEPG-US Model 431537 EOL Plate per
Standard
ULC-5524.
• Wire Class A (Style Z) NACs from “B+” and
“B-” to each appliance. No end-of-line is
needed for Class A. Connect wires fro m “+”
and “-” on the last appliance to “A+” and A-”
on the EPS.
• The 10 k, 0.5 W (brown/black/ orange)
resistor (factory installed) should remain
installed across “B+” and “B-” on unused
NACs to keep them in the "normal" state.
• Current rating: Each NAC supplies 2 A
(special application). EPS provides 3 A,
which is split between AUX 24 V and NAC
loads. Refer to the NAC ratings section of
these instructions for circuit loading
restrictions.
• Terminal designations are for the alarm state (+/-).
• If wiring is routed outside the bui lding, use of a listed secondary
protector is required. Use 2 081-9028 or 2081-9044. A protector
must be installed at each bu ildin g exi t/ent ra nce. Each20 81- 9028
adds 0.2 Ohms wiring resistance. 2081-9044 adds 6 Ohms
resistance.
• The wiring chart to the right gives the maximum distance for 0.25
A to 2 A loads.
For Class B, distance = panel terminals to the last appliance.
For Class A, distance = EPS terminals to the las t appliance and
back to the EPS terminals.
• When using non-addressable Series 4901, 4903, and 4904 twowire audible/visible applianc es , max i mum wi rin g capacitance is
0.22 uF. Determine wiring capacitance by adding wire-to-wire
capacitance plus wire-to-shield capacitance (if shield is used).
Multiply the result by the wire length in feet. Example: A 12 AWG
FPLR is rated at 100 pF/foot, with no shield. The 0.22 uF limit
allows a maximum length of 2,200 ft. Also check th e wiring
distance chart, right, to determine that the voltage drop will not
be excessive.
• Max. number of Smart Sync appliances = 2 A divided by the
current draw amperage of the appliances used.

• If wiring is routed outside the building, use of a listed secondary protector is required. Use 2081-9044or 2081-9028. A
protector must be installed at each building exit/entrance. Each 2081-9044 adds 6 Ohms resistance at 200 mA. Each
2081-9028 adds 0.2 Ohms wiring resistance, and is rated for more than the 0.5 A aux 24 V capacity.
• If the circuit is used to power the Model 4098-9682 Four-Wire Base, the auxiliary 24 V power must be routed through the
2098-9735 End-Of-Line Relay, as shown in Figure 6 (below).
