Output Control
The module provides up to 32 open collector control outputs for activating devices such as relays,
indicators, or other on/off devices. The outputs can be active high (off) or active low (on). Additionally,
they can be momentary (pulsed) or maintained type activation. The programming of the system master
controller defines how the outputs are activated. Each output is individually programmed to activate
during a certain system event.
Accessory Device to the GAI-Tronics AMI
There are two ways the device can be used with the AMI:
• Input/output extension module - This application provides 32 additional switch inputs to the AMI
that can be programmed for alarm activation, alarm reset, muting, or telephone interface control
switches.
• Serial data alarm control - This application allows the system master controller to activate and reset
alarms on the AMI from a remote location without using contact closure inputs wired directly to the
AMI.
Each allocation requires a unique data connection to the AMI. Refer to the Installation section for wiring
diagrams.
Data Line Selection and Settings
The Model 12584-002 I/O Control Module supports both RS485 and RS232 data connections. The
RJ232 connection is accessed from a male DB-9 connector. There are two different RS485 data
connections. RS485 #1 is accessed from terminal block TB1 and TB2, and RS485 #2 is accessed on an
RJ45 receptacle.
• Data connection to system master controller must be made using either the RS485 #1 data connection
OR the RS232 data connection. Both cannot be used simultaneously.
A 3-position jumper (J6) selects either RS232 or RS485 #1 data communication.
- Short pins 1 and 2 to select RS485 data on TB2.
- Short pins 2 and 3 to select RS232 data on DB9 connector.
RS485 #1 data connection is made to terminal blocks TB1 and TB2. Refer to Table 7 and Table 8 in
the Installation section of this manual for data line connection details.
RS232 data connection is made to the male DB-9 connector. A null-modem cable should be used for
connection to the master controlling device.
• The RJ45 receptacle connection is used exclusively for serial data control of the AMI as mentioned
above. Refer to Table 9 in the Installation section of this manual for data line connection details. Do
not use this data connection for the system master controller.
After selecting the data line type, there are several other switches on the I/O Control Module that must be
set to the proper data format to communicate with the controlling device. Each switch is labeled on the
module case. The following sections describe each switch in detail.
