4. Connect devices to be powered:
a. For Power Supply Board: connect to the terminals marked [+ DC -] (Fig. 1, pg. 5).
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) or 1 to 8 marked [1P & 1N] through [8P & 8N] (Fig. 3, pg. 6),
carefully observing correct polarity.
5. 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.
6. Connect appropriate signaling notification devices to the terminals marked [AC FAIL & BAT FAIL] (Fig. 1, pg. 5)
supervisory relay outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay must be used to
provide a visual indication of AC power on.
Wiring:
Use 14 AWG or larger for all power connections.
Note: Take care to keep power-limited circuits separate from non power-limited wiring (115VAC, 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.
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage 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 0.7A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
