ALCN-792MISO/D Isolated Quad Loop Adder Module

Mircom ALCN-792MISO/D Isolated Quad Loop Adder Module Owner's manual

  • Hello, I'm your chat assistant. I have reviewed the datasheet for the Mircom ALCN-792MISO and ALCN-792D Loop Adder Module and Daughter Board. This document describes how these modules provide addressable loops for fire alarm systems, with the capability to support up to 1272 devices. I am ready to answer any questions you may have about this device.
  • How many addressable devices does the ALCN-792MISO module support?
    How many addressable devices does the ALCN-792MISO with the ALCN-792D daughter board support?
    What type of wiring is required for the loop circuits?
    What is the max loop resistance?

Description
The ALCN-792MISO Isolated Quad Loop Adder Module
provides two addressable loops plus an additional two
loops as part of the daughter board ALCN-792D which
is mounted over the ALCN-792MISO. The quad loop
adder module provides Signaling Line Circuits (SLC) to
the Flex-Net Addressable Fire Alarm system consisting
of 159 Sensors and 159 Addressable Modules per loop.
Each ALCN-792MISO Loop Controller Module has a
dedicated Central Processor Unit (CPU) and will support
two fully loaded SLC lines which will provide up to 318
addressable devices per SLC line, for a total of up to
636 addressable devices per ALCN-792MISO Quad
Loop Controller module.
The ALCN-792MISO occupies one module space on
any FleX-Net FX-2000N Series control panel chassis
The ALCN-792D daughter board provides two additional
SLC lines for up to 318 addressable devices per SLC
line, for a total of up to 1,272 addressable devices per
combination ALCN-792MISO with ALCN-792D.
Features
Isolated
Dedicated Central Processor Unit (CPU) per
module
Expands system capacity to 636 addressable
devices on 2 loops, 159/159 per loop
With the addition of the ALCN-792D this expands
module an additional 2 loops bringing module
capacity to 1272 addressable devices.
