12/24 VDC (field selectable), 8 power supplies for systems integration. Common access control and
security system applications include powering door strikes, mag locks, card readers and other
accessory devices.
II. Installation Instructions
1. Mount cabinet/board per mechanical dimensions and knockouts given in section III / VII.
2. Connect 120VAC,60 HZ., single phase to the black and white leads of the transformer in
accordance with Article 725 of the National Electrical Code , Article 16 of the Canadian Electrical
Code or other applicable codes.
3. Low Voltage AC Input - Connect to Secondary winding of the transformer. Transformer output
voltage is approximately 28VAC
4. Configure power supply output by positioning the appropriate jumpers

Output Voltage
5. Verify Output voltage by measuring output present at “DC1” output and “Battery “ terminals.
6. If optional batteries are present, connect battery set to “Battery” terminals (see Fig. IV). CAUTION:
Observe polarity; incorrect polarity may damage batteries. Recommended battery type -
PowerSonic (PS Series) or YUASA (NP - Series) sealed lead acid/gel cell.
7. Connect user system to “DC1” and/or FAI controlled “DC2” terminals. Caution: Observe polarity;
incorrect polarity may damage user system. Refer to Section 1 for Maximum Allowable Current.
8. FAI controlled Output (DC2) operation:
a. For power presence with a n/o circuit to FAI connector, set S1 to 1 & 3. (Default setting)
b. For power present on a n/c circuit to FAI, connector, set S1 to 2 & 3
9. AC and DC fault outputs are reported via Form “C” relays;
a. “AC” fault relay maximum contact switching : 30VDC/5A
b. ‘DC’ fault relay maximum contact switching : 30VDC/5A
10.Visual Indicators:
a. Green AC LED (D5) Low Voltage AC Presence
b. Green DC OK LED (D17) Regulator Voltage Output Presence
c. Red DC1 LED (D11) DC1 Output Voltage Presence
