The LAN Power Supply is a dual 2A supervised power supply producing 4A nominally split evenly between system power and dedicated battery charging.

Up to three additional LAN Power Supplies can be slaved to one LAN Power Supply. Each slave can be configured ifferently to tailor power output to system requirements.

Ganged LAN Power Supplies come into their own in installations where express charging of large back up battery banks is needed.

The LAN Power Supply connects to the Concept system LAN, communicating status of the supply and is applicable where battery backed 12V supplies are required to power other unpowered Inner Range modules, detectors, readers and auxiliary devices such as strobes, sounders, locks, etc.

Features:

  • Dual 2A power supply (2A system power + 2A battery charging)
  • Up to 4 units can be linked in a master / slave layout to provide 14A dedicated for charging or detector power. Slaves can be configured as:
    • Split (2A power / 2A charging)
    • Charger only
    • Power only
    • Spare
  • Reports status of fault, tamper plus input and output conditions to Control Module through Concept LAN
  • Contains 2 general purpose zone inputs
  • Additional switched 12V output auxiliary with current monitoring for use with satellite sirens
  • 12V auxiliary can be used as 12V power source for strobes, 12V lamps when current monitoring switched off
