I/O Modules

Each Input/Output (I/O) module can accept up to two field contact inputs, with
field contact voltage (FCV) provided either internally by the Annunciator or
externally by the customer. Each input includes optical coupler isolation and can
be selected for Normally Open (N/O) or Normally Closed (N/C) Field Contact
Inputs through the software configuration or module jumpers. The I/O module
provides outputs to the Display Module. Optional relays can be added to the I/O
module for repeating the alarm status. Up to two I/O cards can be inserted into
Card Slots 1 & 3 of a single cell for a maximum of 4 points per cell. The Cell with
the Common Service Module can also support one I/O Module (in slot 3), in
place of the Integral Pushbuttons.
There are two versions of input modules. One version has headers and jumpers
used to configure the FCV and the CSM address, while the other versions are
designed with an input circuit capable of accepting an input range of 24vDC to
125vDC and use a rocker switch for the CSM Address.
Both versions of the I/O module are configured via jumpers for: (NO/NC) and
Form A, B, C Relay Contacts.
Refer to the following table and to the part number affixed to the module to
determine the type of module. Note that all modules in a systems shipped from
the factory will contain the same type of configuration.

Field Contact Type

The I/O module supports both N/O & N/C inputs through the software
configuration, as detailed in the next section. N/O refers to Normally Open Field
Contacts (open in Normal State, Closed in Alarm State) and N/C refers to
Normally Closed Field Contacts (closed in Normal State, open in Alarm State)
As an alternative, the N/O and N/C settings may be selected via jumper P5 & P6
on the I/O Module.
NOTE: The NO/NC setting must only be configured via one method (hardware
or software). It is recommended to use the software method to avoid any
confusion.
