Installing the Decoder Assembly into Back Boxes
Overview

Guidelines
4100U/4100ES
Guidelines
The decoder is a 4100-family "slave" card. It uses six inches of mounting space, and requires
connection to the 4100 POWER and COMM buses, either by harness from an adjacent bay, or
from the "P1" edge connector and an adjacent card on the bus. Decoders must be mounted to the
right of other slave cards, to facilitate access to the programming interface. When used on the
4100 bus, the decoder will take COMM and +24 V power from the P1 connector. When used in an
RUI application, two-wire COMM and +24 V power are connected to TB3.
The decoder module can be mounted to either 4100 Back Boxes (PID series 2975-91xx) or
4100U/4100ES Back Boxes (PID series 2975-94xx).
•
The 4100/4120-0136 version is used for systems with 4100 Back Boxes (non-
4100U/4100ES).
•
The 4100-6045 version is used for systems with 4100U/4100ES Back Boxes.
Review the following guidelines before mounting the assembly into the 4100 , 4100U, or 4100ES.
•
If a power supply is installed in the bay, it must be installed on the far right of the bay
and any relay modules must be installed in the slots immediately to its left.
•
Relay cards must be installed in the rightmost possible slots. This is necessary to allow
for the proper routing of non-power limited wiring (typically 120 VAC wiring), which
could be connected to a relay module.
•
If a 4100/4120-0155 SDACT, 4100-6052 Event Reporting DACT, 4100-6053 Point
Reporting DACT, or a 4100/4120-0153 CCDACT is installed in the bay, it must be
installed in the far left or far right slot. Neither of these modules contains the J1 or P1
connectors, which are used to distribute power and communications to adjacent modules.
Review the following guidelines before mounting the assembly into a 4100 system.
•
Only the 4100/4120-0136 module with a 617-655 Mounting Plate can be mounted into a
4100 Back Box.
•
The mounting plate takes up 6 inches of space in the bay.
•
Master controller bay only: If the 575-274 Master Motherboard is used, it must be
installed in the leftmost position of this bay. If the 575-274 Master Motherboard is not
used, the CPU motherboard must be installed in the leftmost position of the bay.
Review the following guidelines and instructions before mounting the assembly into a
4100U/4100ES system.
•
Only the 4100-6045 module can be mounted into a 4100U/4100ES Back Box.
•
The mounting plate takes up 6 inches of space in the bay.
To mount in this type of bay, standoffs must be used. Follow the instructions below.
1. Screw four metal hollow threaded standoffs into the screwholes on the chassis.
2. Orient the motherboard with the connector labeled J1 on the right and the header labeled P1
on the left.
3. Secure the motherboard to the standoffs using four #6 torx screws and hex nuts.
