Configuring Global Alarm Settings
The Global Alarm Set Up screen is accessed by selecting the Global Alarm Set Up
option from the Alarm menu. It is used to control the overall alarm setup, how responses
are reset and the state the system returns to when all responses are clear.
Response Modes
In this screen, the user can choose from five different Display mode settings, which are
used to define how triggered alarms, and hence triggered responses, appear on monitors.
However, these modes operate differently depending on the selected Response mode.
The available response modes are ACK (Acknowledge), TRANSP (Transparent) and
TIMEOUT:
ACK - Acknowledge Alarm Responses
The response is active from the time the alarm is triggered to the time it is manually
cleared by an operator (by selecting the monitor displaying the response and pressing
the ALARM ACKNOWLEDGE
key).
TRANSP - Transparent Alarm Responses
The response is active until it is manually cleared (by pressing the ALARM
ACKNOWLEDGE key) or until the alarm contacts return to their resting state. The
Transp. T/O Mode menu item is used to specify the minimum time (between 2 and 99
seconds) which a transparent alarm’s response is displayed for when the contacts reset
immediately.
TIMEOUT - Timeout Alarm Responses
The response is active until it is manually cleared (by pressing the ALARM
ACKNOWLEDGE
key) or until the timeout period specified in the Timeout menu item
expires (between 2 and 99 seconds). The timeout operates regardless of whether the
alarm contacts have returned to their resting state or not.
