Altronix AL100UL User manual

Overview:
The AL100UL power supply converts 16.5VAC, 20VA to a 12VDC power-limited output (see specifications).
The AL100UL is UL Listed for Burglar Alarm applications.

Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local
codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount the unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two upper
screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 4). Secure
enclosure to earth ground (Fig 1, pg. 2).
2. Connect a 16.5VAC, 20VA Class 2, UL Listed plug-in transformer to the terminals marked [AC, AC] (Fig 1, pg. 2).
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect devices to be powered to the terminals marked [--- D C + ] (Fig 1, pg. 2).
5. Connect the stand-by battery to the terminals marked [--- B A T + ] (Fig 1, pg. 2) (battery leads included).
6. Connect appropriate signaling notification devices to the AC Fail and Low Bat supervisory relay outputs
terminals marked [LOW BAT - NC, C, NO, AC FAIL - NC, C, NO] (Fig 1, pg. 2).
Note: To meet UL requirements, AC Supervisory outputs must be connected to the zone of Alarm Control Panel
or to visual AC trouble indicator.
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. When the use of stand-by batteries is desired, they must be lead acid or gel type.

The lightning flash with arrow head symbol within an equilateral triangle is intended to alert the user to the
presence of an insulated DANGEROUS VOLTAGE within the product’s enclosure that may be of sufficient
magnitude to constitute an electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the literature accompanying the appliance.
CAUTION: To reduce the risk of electric shock do not open enclosure. There are
no user serviceable parts inside. Refer servicing to qualified service personnel.
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
(Stand-by Specifications Chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the bat-
tery terminal and at the board terminals marked [--- B AT + ] to ensure that there is no break in the battery connection wires.
Note: Maximum charging current under discharge is 500mA.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
LED Diagnostics:
Red (DC) Green (AC) Power Supply Status
ON ON Normal operating condition.
ON OFF Loss of AC. Stand-by battery supplying power.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or no stand-by battery. No DC output.
