Altronix AL842ADA220 NAC Power Extender Installation Guide

Altronix AL842ADA220 NAC Power Extender

Overview

Altronix AL842ADA220 is an extremely cost-effective 10A 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 1A auxiliary output for 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. i.e. March Time Input, March Time Output). 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 ground wire lead to earth ground lug (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.

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] and [IN2] and desired output signal type (Output Programming Selection Table, pg. 4).

6. Connect FACP output to the desired AL842LGK logic board inputs, and notification appliances to the desired AL842LGK logic board outputs (see 42 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.

Output Programming Selection Table

Outputs must be programmed independently (OUT1 – OUT4)

the corresponding input (i.e. FACP Sync module – maintains synchronization of notification appliance circuit).
Temporal Code 3 Mode| 3| 1, 2| Enables Temporal Code 3 signal generation output. This mode will accept a steady or a pulsing input.
Steady Mode|  | 1, 2, 3| A steady output signal will be generated.

This mode will accept steady or pulsing input.

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). This allows audible notification appliances (horns) to be silenced while visual notification appliances (strobes) continue to operate. The FACP must be capable of a visual annunciation to the silencing status of the output or zone(s) to which the AL842ADA220 (NAC Power Extender) is connected.

(Supervised)

| These terminals connect to the 24VDC FACP notification appliance circuit outputs. (Class A, Style Z or Class B, Style W, X, Y) Input trigger voltage is 8-33VDC @ 5mA min. Terminal polarity is shown in alarm condition. During an alarm condition these inputs will cause the selected outputs chosen to drive notification appliances. The designated outputs are set by

output switches [OUT1 through OUT4] (Output Programming Selection Table, pg. 4). A trouble condition on an output loop will cause the corresponding input to trip the FACP by opening the FACP loop. An alarm condition will always override trouble to drive notification appliances.

(Supervised)

| For Class A, Style Z hookups these terminal pairs return to FACP NAC1 and/or NAC2. For Class B, Style W, X, Y hookups the FACP EOL resistor from the NAC1 and/or NAC2 outputs are terminated at these terminals. Optionally, other notification appliances or additional signal- ing circuit power supplies may be connected to these terminals. If this option is chosen, the EOL resistor must be terminated at the last device.

| An open across these inputs, will cause the selected outputs chosen to drive notification appliances. The designated outputs are set by output switches [OUT1 through OUT4] (Output Programming Selection Table, pg. 4).

  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 with in 180 seconds after battery remains undetected (missing or removed). A restored battery will report within 30 seconds.

• Indicates existing trouble condition. When a trouble condition (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.
• Indicates trouble condition memory. When a trouble condition restores, the units red output LEDs, [OUT1] – [OUT4] will blink with a shorter and distinctly different duration.
  • The green input LEDs will be off (normal condition).
  • To reset the memory depress the reset button located on the AL842LGK logic board (Fig. 2c, pg. 8).
  • The LED(s) will extinguish.
    Note: When indicating circuits have restored, trouble memory reset is not required for normal operation.

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 20ft 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 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 10A @ 250V. Output fuse rating is 15A @ 32V.
• Note: Maximum charging current is 3.2A.
• Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
