Installation Instructions Instruction Manual

Overview:
OLS120 power supply/charger converts 115VAC, 60Hz or 230VAC, 50Hz input into a 12VDC or 24VDC @ 4 amp of
continuous supply current (see specifications). This general purpose power supply has a wide range of applications for
access control and security system accessories that require additional power.

12VDC SW 1 - Closed 4 amp
24VDC SW1 - Open 4 amp
Installation Instructions:
The OLS120 should be installed in accordance with The National Electrical Code and all applicable Local Regulations.
1. Mount the OLS120 in the desired location/enclosure.
2. Slide [Power ON/OFF] switch t o OFF position.
3. Set the OLS120 to the desired DC output voltage via SW1 (Voltage Output Selection Table).
4. Connect AC power to the terminals marked [L & N], connect ground to the terminal marked [G].
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. Measure output voltage before connecting devices. This helps avoiding potential damage.
6. Connect devices to be powered to the terminals marked [-- DC+].
7. When the use of stand-by batteries is desired, they must be lead acid or gel type.
Connect battery to the terminals marked [-- BAT +] (battery leads included).
Use two (2) 12VDC batteries connected in series for 24VDC operation.
8. When batteries are not used, a loss of AC will result in the loss of output voltage.
9. Connect appropriate signaling notification devices to AC Fail & Low battery supervisory
relay outputs marked [NC, C, NO].
10. Slide [Power ON/OFF] switch to ON position.
