Installation Instructions:
The AL600ULB should be installed in accordance with article 760 of The National Electrical Code as well as NFPA 72 and all applicable Local Codes.
- Mount the AL600ULB in the desired location/enclosure (mounting hardware included).
- Set the AL600ULB to the desired DC output voltage by setting SW1 to the appropriate position (refer to Power Supply Output Selection chart).
- Connect two (2) 28VAC/100VA transformers (connected in parallel) to the terminals marked [AC].
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.
CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel. - Measure output voltage before connecting device. This helps avoiding potential damage.
- Connect devices to be powered to the terminals marked [+ DC –] (Fig. 1, pg. 2). When servicing the unit, AC mains should be removed.
- 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 battery to the terminals marked [+ BAT –] (Fig. 1, pg. 2). - Connect appropriate signaling notification devices to [AC FAIL & BAT FAIL] (Fig. 1, pg. 2) 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.
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 Specification 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.
