Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with
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 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. Set the unit to the desired DC output voltage by setting SW1 (Fig. 1c, pg. 5) to the appropriate position
(Power Supply Output Specification Chart, pg. 2).
3. Secure cabinet to earth gourd. Connect AC power (115VAC, 60 Hz) to the terminals marked [L, N]
(Fig. 1, pg. 5). Use 14 AWG or larger for all power connections (Battery, DC output, AC input).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low Battery reporting).
Keep power-limited wiring separate from non-power limited wiring (115VAC / 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. 6).
4. Measure output voltage before connecting devices. This helps avoiding potential damage.
When servicing the unit, AC mains should be removed.
5. Connect devices to the terminals marked [+ DC –] (Fig. 1, 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 one (1) 12VDC battery to the terminals marked [+ BAT –] for 12VDC operation.
Use two (2) 12VDC batteries wired in series for 24VDC operation.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1a, pg. 5) supervisory
relay outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on. To delay report for 6 hours cut “AC Delay” jumper
(Fig. 1b, pg. 5).
8. Please ensure that the cover is secured with the provided key lock.
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 (refer to Power Supply Voltage Output Specifications chart).
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 discharge is 0.7A.
Note: Expected battery life is 5 years, however it is recommended changing batteries
in 4 years or less if needed.
