Section 5 – Recorder Setup
Page 62 09/11/2008 REV 0.99
Event Message: Enter a message in the entry box (up to a maximum of 20 characters) that will be
appended to the alarm/event log message if the check box to the left is checked. This message will also
be appended to the email if the notify box is checked (see above).
Audio File: The recorder can play a .wav file (PCM type only) instead of the standard alarm sound.
These audio files must be saved in the system internal memory (SD Card). The drop down box shows
available files. Select the file to be played or none to use the default sound.
Contact: This is the relay output contact that will be activated when the alarm is true. You need to have
an optional digital I/O board in the system which needs to be set up correctly. The contact has to be
enabled. If no contact output is required, set this to None. If you need to set up the contact, press the
Setup button alongside the contact number to get to the Digital Output Setup window.
5.5 Digital Input/Output
The Digital Input/Output features require an optional card which is plugged into the rear of the recorder. This card
will have some combination of up to 12 relays (outputs) and 6 opto-isolated inputs, depending on model number.
Check the specifications of the card you have for the output ratings and type of the relays and the input voltage of
the opto-isolated inputs.
In order to make use of the Digital Input/Output capabilities of the recorder, these need to be setup and initialized
before use. Setup can be done through the Utility Setup Menu when defining or editing widgets.
The status of the digital outputs is indicated by the icon on the Task Bar which also doubles as the Alarm Reset
button. The Alarm Reset button will drop out any contacts that are latched and no longer in alarm, or any alarm
that is set to drop out on reset. The status is indicated as follows:
- Relay outputs all reset – safe condition
- One or more relay outputs active – alarm condition
The relay outputs can be configured in a number of ways. It is up to the user to ensure that connection and
external circuitry agree with what is set up in the relay configuration menus. The output types are as follows:
Normal: The relays are normally not energized but will energize in an alarm condition and return to normal
when the alarm clears, or will clear when the Acknowledge button is pressed if this option is set.
Latching: The relays are normally not energized but will energize in an alarm condition and will NOT return to
normal when the alarm clears, until the Acknowledge button is pressed or unless the Acknowledge button is
pressed if this option is set.
Reflash: The Reflash option programs the relays to momentarily open and reclose each time an additional
alarm that is programmed to close the contacts is acquired.
Failsafe: This is an option that can be applied to each relay output. The Failsafe option allows the relay
outputs to function as Failsafe Contacts. This reverses the logic so a contact which is normally OPEN will be
energized normally CLOSED. The Failsafe contact will drop out in the event of a power failure and indicate an
alarm.
The digital inputs are opto-coupled led types. They typically operate from 3 to 12 volts DC but can be wired for
higher input voltages. Each input has an isolated positive (+) and negative (-) connection. Check the information
that came with the card for further details.
