The following units provide non power-limited outputs: eFlow102N, eFlow102NX, eFlow102N8, eFlow102NX8, eFlow102N16,and eFlow102NX16.
The following units provide Class 2 power-limited outputs: eFlow102N8D, eFlow102NX8D, eFlow102N16D, and eFlow102NX16D.
If a power-limited output is required in the end-product application, the DC output from the power supply must be connected to a separately Listed control unit or accessory board that provides power-limited outputs. The product(s) providing the power-limited output(s) must be listed as appropriate for the particular end-product application (fire alarm, burglar alarm, access control), and wired in accordance with the product’s installation instructions. Class 1 wiring methods, separation of circuits, and proper fire-rated enclosures all must be considered when connecting the DC output of the power supply to the end-product devices. The auxiliary output of these units is power-limited.

eFlow102N, eFlow102N8, eFlow102N8D, eFlow102N16, eFlow102N16D:
13.5” x 13” x 3.25”(342.9mm x 330.2mm x 82.6mm).
eFlow102NX, eFlow102NX8, eFlow102NX8D, eFlow102NX16, eFlow102NX16D:
15.5” x 12” x 4.5”(393.7mm x 304.8mm x 114.3mm).
Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, The Canadian Electrical Code, Part 1, and with all local codes and authorities having jurisdiction. The product must be located indoors within the protected premises.
- Mount the unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the two upper screws, level and secure. Mark the position of the lower two holes. Remove the enclosure. Drill the lower holes and install the two fasteners. Place the enclosure’s upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pgs. 11-12). Secure enclosure to earth ground.
- Connect unswitched AC power (120VAC, 60Hz) to terminals marked [L, N] (Fig. 1a, pg. 5). Green “AC” LED on the power supply board will turn on. This light can be seen through the LED lens on the door of the enclosure. Use 14 AWG or larger for all power connections. Secure green wire leads to earth ground. Keep power-limited wiring separate from non-power-limited wiring (120VAC 60Hz Input, Battery Wires). Minimum 0.25” spacing must be provided.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment. There are no user-serviceable parts inside. Refer installation and servicing to qualified service personnel.
For Fire Alarm applications the outputs are “Special Applications” only, see the list (refer to Appendix A, pg. 12). - Measure output voltage before connecting devices. This helps avoid potential damage.
- Connect devices to be powered:
a. For eFlow102N/eFlow102NX connect devices to terminals marked [– DC +] (Fig. 1h, pg. 5).
b. For other Power Distribution Models connect devices to be powered to terminal pairs 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3a & 3b, pg. 6) or 1 to 16 marked [1P & 1N] through [16P & 16N] (Fig. 4a & 4b, pg. 6) carefully observing correct polarity.
For auxiliary device connection, this output will not be affected by Low Power Disconnect or Fire Alarm
Interface. Connect the device to terminals marked [+ AUX –] (Fig. 1f, pg. 5). - For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the loss of the output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type. Connect the battery to terminals marked [– BAT +] (Fig. 1g, pg. 5). Use batteries – Castle CL1270 (12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries, or UL-recognized BAZR2 batteries of an appropriate rating.
- Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1b, pg. 5) supervisory relay outputs.
- To delay AC reporting for 2 hrs. set the DIP switch [AC Delay] to the OFF position (Fig. 1c, pg. 5).
To delay AC reporting for 1 min. set DIP switch [AC Delay] to ON position (Fig. 1c, pg. 5).
Note: Must be set to ON position for Burglar Alarm Applications. - To enable Fire Alarm Disconnect set the DIP switch [Shutdown] to ON position (Fig. 1c, pg. 5).
To disable Fire Alarm Disconnect set the DIP switch [Shutdown] to OFF position (Fig. 1c, pg. 5). - Trigger terminals are end-of-a-line resistor supervised (10k ohms). Opening or shorting trigger terminals will cause [DC] output to shut down (Fig. 1d, pg. 5).
- Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching [Trigger EOL Shutdown] (Fig. 1e, pg. 5).
- For Access Control Applications: mount UL Listed tamper switch (Altronix model TS112 or equivalent) at the top of the enclosure. Slide tamper switch bracket onto the edge of the enclosure approx. 2” from the right side (Fig. 5, pg. 7 or Fig. 7, pg. 9). Connect tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device.
Wiring:
Use 18 AWG or larger for all low voltage power connections.
Note: Take care to keep power-limited circuits separate from non-power-limited wiring (120VAC, Battery).
Maintenance:
The unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level eFlow102N: 12VDC nominal rated @ 10A max.
Battery Test: Under normal load, conditions check that the battery is fully charged, and check the specified voltage (12VDC @ 13.2) both at the battery terminal and at the board terminals marked [– BAT +] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 1.54A.
Note: Expected battery life is 5 years, however, it is recommended to change batteries in 4 years or less if needed.

NEC Power-Limited Wiring Requirements for eFlow102N Models:
Power-limited and non-power-limited circuit wiring must remain separated in the cabinet. All power-limited circuit wiring must remain at least 0.25” away from any non-power-limited circuit wiring. Furthermore, all power-limited circuit wiring and non-power-limited circuit wiring must enter and exit the cabinet through different conduits. One such example of this is shown below. Your specific application may require different conduit knockouts to be used. Any conduit knockouts may be used. For power-limited applications the use of conduit is optional. All field wiring connections must be made employing suitable gauge CM or FPL jacketed wire (or equivalent substitute). Optional UL Listed battery enclosure must be mounted adjacent to the power supply via Class 1 wiring methods. For Canadian installations use shielded wiring for all connections.
Note: Refer to the wire handling drawing below for the proper way to install the CM or FPL jacketed wire (Fig. 6a).

CAUTION: The power supply board is factory set for 12VDC. Use only one (1) 12VDC stand-by battery.
Keep power-limited wiring separate from non-power-limited. Use minimum 0.25″ spacing.
12AH Rechargeable batteries are the largest batteries that can fit in this enclosure.
A UL-listed external battery enclosure must be used if using 40AH or 65AH batteries.
