**Overview:

**

Altronix eFlow104NK8 and eFlow104NK8D convert a 120VAC 60Hz input into eight (8) fuse or PTC protected 12VDC or 24VDC outputs with a total of 10A max. Units include an unswitched aux. output. They also offer a suite of features that includes fire alarm disconnect, over-voltage protection, and low power disconnect which prevents deep discharge of stand-by batteries. Dual input design allows power to be steered from two (2) factory-installed independent low voltage 12 or 24VDC Altronix power supplies to eight (8) independently controlled fuse (eFlow104NK8) or PTC (eFlow104NK8D) protected outputs.

  Enclosure Dimensions (approximate H x W x D): 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 and with all local codes and authorities having jurisdiction. The product is intended for indoor use only.

1.  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, pg. 8). Secure enclosure to earth ground.

2. Ensure all output jumpers [OUT1 – OUT8] are placed in the OFF (center) position marked [•]. (Fig. 1, pg. 4).

3. Connect unswitched AC power (120VAC 60Hz) to terminals marked [L, N] (Fig. 2a, pg.

4. The 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.

5. Set each output [OUT1] – [OUT8] to route power from Input 1 or 2 (Fig. 1, pg. 3).
   Note: Measure output voltage before connecting devices. This helps avoid potential damage.

6. Turn the power off before connecting devices.

7. Output Connections: Connect devices to terminal pairs 1 to 8, marked [P (Positive) – OUT1-OUT8, N (Negative)] on PDS8(CB), carefully observing polarity.

8. Stand-by Battery Connections (Fig. 3, pg. 7):
   For the U.S. Access Control applications batteries are optional. Batteries are required for Canadian installations (ULC-S319). 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 leads to the terminals marked [– BAT +] on eFlow104NB (Fig. 2g, pg. 5).
   Use two (2) 12VDC batteries connected in series for 24VDC operation (battery leads included).
   Use batteries – Castle CL1270 (12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL-recognized BAZR2 and BAZR8 batteries of an appropriate rating.

9. To delay AC reporting for 2 hrs. set the DIP switch [AC Delay] to the OFF position (Fig. 2c, pg. 5).
   To delay AC reporting for 1 min. set DIP switch [AC Delay] to ON position (Fig. 2c, pg. 5).

10. Fire Alarm Disconnect (Fig. 2c, pg. 5):
    To enable Fire Alarm Disconnect set the DIP switch [Shutdown] to ON position.
    To disable Fire Alarm Disconnect set the DIP switch [Shutdown] to OFF position.

11. Turn the main power on after all devices are connected.

12. Installation of Tamper Switch: Mount UL Listed tamper switch (Altronix model TS112 or equivalent) at the top of the enclosure. Slide the tamper switch bracket onto the edge of the enclosure approximately 2” from the right side (Fig. 3a, pg. 7). Connect the tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device. To activate the alarm signal open the door of the enclosure.

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 eFlow104NB: 24VDC nominal rated @ 10A max.
Battery Test: Under normal load, conditions check that the battery is fully charged, and check the specified voltage (24VDC @ 26.4) 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.
