Technical Specification

Features:
  • Make: Gallagher
  • Model code: 4H Module
  • Voltage: 13.6 V DC

The 8H and 4H modules allow HBUS devices to be star-wired back to a secure controller cabinet. Star-wiring can remove the risk of one faulty connection taking down all downstream devices as on a daisy-chained run, and each HBUS port can support multiple HBUS devices. Gallagher 8H and 4H modules have on-board inputs and outputs for door monitoring and control or general I/O functions. Gallagher 8H and 4H modules monitor and report the state of balanced inputs, and enforce decisions to switch output relays.
