Mircom ALCN-792MISO/D Isolated Quad Loop Adder Module
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.
