Altronix AL842ADA220 NAC Power Supply - 4 Class A or 4 Class B Outputs

Altronix AL842ADA220 NAC Power Supply - 4 Class A or 4 Class B Outputs

AL842ADA220 is an extremely cost effective voltage regulated remote NAC Power Extenders. They may be connected to any 24 volt Fire Alarm Control Panel (FACP). Primary applications include Notification Appliance Circuit (NAC) expansion (supports ADA requirements) and providing auxiliary power to support system accessories.

Key Features:

• Input

  • Power input 220VAC (working range 198VAC - 256VAC) 50/60 Hz, 2.5A.
  • Two (2) Class A, Style Z or two (2) Class B, Style W, X, Y FACP inputs.
  • Two (2) NC dry contact trigger inputs.

• Output

  • 24VDC voltage regulated power limited outputs.
  • 8A max total alarm current.
  • 2.5A max current per output.
  • Two auxiliary outputs rated at 1A each (1A continuous, 1A AC disconnect).
  • Two (2) outputs may be paralleled for more power on an indicating circuit.

  • Programmable supervised indicating circuit outputs:

    • Four (4) Class B, Style W, X, Y or Four (4) Class A, Style Z or Two (2) Class A, Style Z and Two (2) Class B, Style W, X, Y.
  • Thermal and short circuit protection with auto reset.

• Battery Backup

  • Built-in charger for sealed lead acid or gel type batteries.
  • Automatic switchover to stand-by battery when AC fails.
  • Zero voltage drop when switching over to battery backup.

• Supervision

  • AC fail supervision (form "C" contact, 1A/28VDC).
  • Factory set for 1 minute with optional 2 hour delay setting (field selectable).
  • Instant local AC trouble reporting relay (form "C" contact, 1A/28VDC).
  • Battery presence and low battery supervision (form "C" contact, 1A/28VDC).

• Visual Indicators

  • Input and output status LED indicators.

• Special Features

  • 2-wire horn/strobe Sync mode allows audible notification appliances (horns) to be silenced while visual notification appliances (strobes) continue to operate.
  • Sync protocols include Potter/Amseco, Faraday, Gentex®, System Sensor®, and CooperWheelock®.
