Altronix AL802ADA220 NAC Power Extender

Overview:

Altronix AL802ADA220 is an extremely cost-effective 8A remote power supply/battery charger. It may be con-nected to any 12 or 24 volt Fire Alarm Control Panel (FACP). Primary applications include Notification Appliance Circuit (NAC such as strobes and horns) expansion support to meet ADA requirements. It also provides auxiliary power to support system accessories. The unit delivers electronically regulated and filtered 24 volt power to Class B, Style W, X, Y or Class A, Style Z NAC loop circuits. Additionally, a separate 1.0A auxiliary output for four (4)-wire smoke detectors is available. The 8A max. alarm current can be divided between the four (4) outputs for powering NAC devices. Each output is rated at 2.5A max., and can be independently programmed for Steady, Temporal Code 3 or Strobe Synchronization. All outputs may be programmed for Input to Output Follower Mode (output will follow input). In non-alarm condition independent loop supervision for Class A, Style Z and/or Class B, Style W, X, Y FACP NAC circuits is provided. In the event of a loop trouble, the FACP will be notified via the steered input (Input 1 or Input 2). In addition, there are common trouble output terminals (NC, C, NO) which are used to indicate general loop/system trouble. A common trouble input is provided for optional NC (normally closed) devices to report trouble to the FACP. Two (2) FACP signaling outputs can be employed and directed to control supervision and power delivery to any combination of the four (4) outputs.

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. 12). Secure enclosure to earth ground (Fig. 1, pg. 3). Small terminal block wire gauges range from 16 AWG to 24 AWG, all others range from 14 AWG to 24 AWG.
2.  Connect the line (L) and neutral (N) terminals to a separate unswitched AC circuit (220VAC, 50/60Hz) dedicated to the Fire Alarm System. Secure ground wire lead to ground lug (Fig. 1, pg. 3).
3.  Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Connect battery to the terminals marked [+ BAT –] on the Power Supply Board (battery leads included). Use two (2) 12VDC batteries connected in series.
5.  Set output selection switches marked [OUT1 through OUT4] to follow corresponding input [IN1 & IN2] and desired output signal type (Output Programming Selection Table, pg. 4).
6. Connect FACP output to the desired AL800LGK9E logic board inputs, and notification appliances to the desired AL800LGK9E logic board outputs (see Application Guide).
   Note: The 2-wire horn/strobe sync mode will only synchronize horns, horn/strobes, strobes with synchronization capability.
7.  For connection of smoke detectors, digital dialer see Optional Hookup Diagram, pg. 8.

Class A, Style Z Class B, Style W, X, Y, SW1 & SW2 Settings:

Output Programming Selection Table:

For the above modes DIP Switch 4 determines which Input controls the corresponding output: Switch 4 in the ON position causes output(s) to be controlled by Input 1. Switch 4 in the OFF position causes output(s) to be controlled by Input 2. Note: It is required to control visual notification appliances (strobes) via Input 1 (IN1) and audible notification appliances (horns) via Input 2 (IN2).

Note: Unit is equipped with 1A max. auxiliary output: “AUX” will remain battery backed up during power outage. For loads connected to “AUX” please refer to battery “Stand-by Specifications”, pg. 3 for ratings. When loads are connected to “AUX” output during alarm condition, the remaining outputs may not exceed 8A total alarm current (example: AUX = 1A, outputs up to 7A).

*Power Board Parameter Specifications:

• AC Fail condition will report approximately 30 seconds after loss of AC. To delay report for 2.5 to 3 hours cut jumper AC DELAY 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.
• Low battery condition will report at approximately 21VDC.
• Battery presence detection will report within 180 seconds after battery remains undetected (missing or removed). A restored battery will report within 30 seconds.

LED Diagnostics:

AL800ADA – Power Supply Board

AL800LGK9E – Logic Board

• Indicates current trouble condition. When trouble (open, short or ground) occurs on a specific output, the corresponding red output LED, [OUT1-OUT4] will blink. The corresponding green input LED will blink as well. Loop trouble will report within 30 seconds.
• Indicates trouble condition memory. When a trouble condition restores, the units red output LED, [OUT1-OUT4] will blink with a shorter and distinctly a different duration. The green input LEDs will be off (normal condition). To reset the memory depress the reset button (Fig. 2c, pg. 8). The LED(s) will extinguish.

Note: If indicating circuits have been restored, memory reset is not required for normal operation of the unit.

Battery Calculation Worksheet

Units are capable of recharging 40AH battery max. If total ampere – hour required exceeds 40AH, decrease AUX current to provide enough stand-by time for the application.

Hookup Diagram:

Optional Hookups:

1.  Battery and AC monitoring: AC or Battery Fail condition will cause the common trouble input [C “FAULT” NC] to report back to the FACP via Input 1 and Input 2. The common trouble input may also be used for other optional supervisory monitoring. (see Power Board Parameter for use of AC Delay, pg. 6) To report AC and Battery Trouble connect the battery and AC Fail relay output shown in (Fig. 2a) to the common trouble input.
2.  Dry contact input [C “DRY1” NC] [C “DRY2” NC] can be used to alarm output from an addressable module (these inputs are unidirection and cannot report back to trigger module). Connection to triggering devices must be made within 20 ft. of distance and using conduit for wiring.
3. Auxiliary output [– AUX +] 24VDC at 1A max.
4. AC Local [NC, NO, C] should connect to the host control panel for local annunciation of the trouble condition. Note: If common trouble input, terminals marked [C “FAULT” NC] are not used, these terminals must be shorted (connect jumper) to remain inactive. For optional hookups see Fig. 2b.

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 (26.2-26.4VDC recommended range).
• 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.
• Fuses: Check input fuse on the power supply board, replace if necessary. Input fuse rating is 5A @ 250V.

Note: Maximum charging current is 3.2A. Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
