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.
1. Mount unit in 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.
2. Set desired DC output voltage by setting SW1 to the appropriate position on the power supply board (Fig. 1i, pg. 5).
3. Connect unswitched AC power (120VAC 60Hz) to terminals marked [L, N] (Fig. 1a, pg. 5). Use 14 AWG or
larger for all power connections. Secure green wire lead 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.
For Fire Alarm applications the outputs are “Special Applications” only, see list (refer to Appendix A, pg. 12).
4. Measure output voltage before connecting devices. This helps avoid potential damage.
5. Connect devices to be powered:
a. For eFlow4N/eFlow4NX connect devices to terminals marked [- DC +] (Fig. 1h, pg. 3).
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) carefully observing correct polarity.
For auxiliary device connection this output will not be affected by Low Power Disconnect or Fire Alarm Interface.
Connect device to terminals marked [+ AUX -- ] (Fig. 1f, pg. 5).
6. For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the loss
of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to terminals marked [-- BAT + ] (Fig. 1g, pg. 5). Use two (2) 12VDC batteries connected in series for
24VDC operation (battery leads included). Use batteries - Casil CL1270 (12V/7AH), CL12120 (12V/12AH),
CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2 batteries of an appropriate rating.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1b, pg. 5) supervisory
relay outputs.
8. To delay AC reporting for 2 hrs. set dip switch [AC Delay] to 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.
9. To enable Low Output Power Shutdown set dip switch [Shutdown] to ON position (Fig. 1c, pg. 5).
To disable Low Output Power Shutdown set dip switch Shutdown] to OFF position (Fig. 1c, pg. 5).
eFlow4N Series - 3 -
10. Trigger terminals are end of a line resistor supervised (10k ohms). Opening or shorting trigger terminals will cause
[DC] output to shutdown (Fig. 1d, pg. 5).
11. Place a jumper for non-latching FACP. A momentary short on these terminals resets FACP latching
[Trigger EOL Shutdown] (Fig. 1e, pg. 5).
12. For Access Control Applications: mount UL Listed tamper switch (Sentrol model 3012 or equivalent) at the top of the
enclosure. Slide tamper switch bracket onto the edge or the enclosure approx. 2” from the right side
(Fig. 4, pg. 7 or Fig. 6, 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:
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
eFlow4N: 12VDC or 24VDC nominal rated @ 4 amp max.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage
(12VDC @ 13.2 or 24VDC @ 26.4) both at battery terminal and at the board terminals marked [-- BAT + ] to insure
there is no break in the battery connection wires.
Note: Maximum charging current under discharges is 1.54 amp.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.

Trouble/Time Limited Warning of Stand-by Batteries:
For compliance with ULC S318-96, the Time Limited Warning circuit must be connected for local or remote annunciation
with an Amber or Red LED to indicate DC Trouble (low battery, loss of battery or when 95% of the stand-by battery has
been depleted). Connect the circuit to the Batt Fail relay contacts to an appropriate input of a UL Listed Burglar Alarm
or Access Control Panel. The following figure shows the circuitry needed for local annunciation.
