2. Connect AC power (115VAC 60Hz) to the terminals marked [L, N] (Fig. 1, pg. 3). Use 18 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. 5).
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered at 5VDC to the terminals marked [+ 5VDC -- ].
5. Connect devices to be powered at 12VDC to the terminals marked [+ 12VDC -- ].
6. Connect devices to be powered at 24VDC to the terminals marked [+ 24VDC -- ].
7. Connect two (2) 12V Stand-by batteries.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in
the loss of output voltage. Batteries must be lead acid or gel type if used. Two (2) 12V Stand-by batteries
connected in series to the terminals marked [+ BAT -- ] (Fig. 1 , pg. 3).
