Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with

Installation Instructions:

all local codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Mount 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 three 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. 7, 8). Secure enclosure to earth ground.

2. Slide [Power ON/OFF] switch t o OFF position.

3. Set SW1 on the power supply board to the desired DC output voltage (Fig. 1c, pg. 5)
(Power Supply Voltage Output Specification Chart).

4. Connect AC power to the terminals marked [L & N], connect ground to the green flying lead (Fig. 1, pg. 5).
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting).

5. Slide [Power ON/OFF] switch to ON position.

6. Measure output voltage before connecting devices. This helps avoiding potential damage.

Keep power-limited wiring separate from non power-limited wiring (115VAC, 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.

7. Slide [Power ON/OFF] switch t o OFF position.

8. Connect devices to be powered:
a. For Power Supply Board connect to the terminals marked [– DC +].
b. For Power Distribution Module(s) connect devices to be powered to the terminal pairs 1 to 4 marked
[1P & 1N] through [4P & 4N] (Fig. 2, pg. 6), 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3, pg. 6),
or 1 to 16 marked [1P & 1N] through [16P & 16N] (Fig. 4, pg. 6), carefully observing correct polarity.
Note: Power switch is used to disconnect the L (HOT) terminal from the rest of the board (Fig. 1a, pg. 5).
When servicing the unit, AC mains should be removed.

9. When using stand-by batteries, they must be lead acid or gel type.
Connect battery to the terminals marked [– BAT +] (battery leads included).
12VDC operation: Use one (1) 12VDC battery.
24VDC operation: Use two (2) 12VDC batteries connected in series.
Note: When batteries are not used, a loss of AC will result in the loss of output voltage.

For supervised models only:

10. Connect appropriate signaling notification devices to AC Fail and Low Bat supervisory relay outputs
marked [NC, C, NO] (Fig. 1b, pg. 5).

11. Slide [Power ON/OFF] switch to ON position.
