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.

1. Mount the AL600ULB in location/enclosure.

2. Set the AL600ULB to the desired DC output voltage by setting SW1 to the appropriate position

(refer to Power Supply Output Selection chart).

3. Connect two (2) 28VAC / 200VA transformers (connected in parallel) to 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 .25” spacing must be provided.

4. Measure output voltage before connecting device. This helps avoid potential damage.

5. Connect devices to be powered to terminals marked [+ DC –] (Fig. 1).

When servicing the unit, AC mains should be removed.

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 battery to terminals marked [+ BAT –] (Fig. 1).

7. Connect appropriate signaling notification devices to [AC FAIL & BAT FAIL] (Fig. 1) 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: PTC2

RLY1

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

AC both at battery terminal and at the board terminals marked [+ BAT –] to insure there is no break in the battery connection wires.

Note: Maximum charging current under discharge is 0.7 amp.

AC

Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.

Function/Description

Connect 28VAC to these terminals from 2 connected in parallel transformers.

12VDC or 24VDC @ 6 amp continuous non-power limited output.

Used to notify loss of AC power, e.g. connect to annunciator/alarm panel. Relay normally energized when AC power is present.

Contact rating 1 amp @ 30VDC. AC Fail condition will report approximately one (1) to one minute after loss of AC. To delay report for 6 hours cut jumper J1 on the

Power Supply Board (AC trouble output delay option). If this mode is selected the Power

Supply Board must be reset by removing all power to it for 30 seconds.

Used to indicate low battery condition, e.g. connect to alarm panel.

Relay normally energized when DC power is present.

Contact rating 1 amp @ 30VDC. Low battery conditions will report approximately 21VDC

(24VDC output setting) or approximately 10.5VDC (12VDC output setting). Battery presence detection will report approximately 1 minute after battery remains undetected

(missing or removed).

Stand-by battery connections. Maximum charge current 1.2 amp.
