%/m or %/ft.
Alarm 2, Alarm 1, Pre-Alarm 2 and Pre-Alarm 1 (IIM and Direct Connection).
These boxes will
display the programmed smoke thresholds, in percent of full scale, for Alarm 1, Pre-Alarm 2 and Pre-
Alarm 1 levels. Alarm 2 is display as %/m or %/ft. obscuration. In each case, there are two levels shown,
one for Day and one for Night. If the Day/Night feature is not enabled, the Night value is ignored. Each

This box indicates whether the feature is enabled or disabled. It also displays the
programmed Day Start Time and Night Start Time in 24-hour format. These times are ignored if the

Isolation
Selecting
<Isolation>
isolates or de-isolates the Detector. Isolation allows the Detector to be tested without
generating alarms on the fire alarm panel. When the Detector is isolated, the Isolate indicator lights and the
Detector will be in a fault condition. No alarm conditions will be reported by the Detector when they are
isolated.
When isolated:
On a Detector, the Alarm 2, Alarm 1, Pre-Alarm 2 or Pre-Alarm 1 indicators do not light.
The Isolate light is yellow and a fault message occurs in the status box. The computer will beep until the
isolation is acknowledged.
The real-time smoke level will continue to be displayed on the bar graph and in the Smoke Status
window.
The Alarm and Pre-Alarm relay outputs are disabled.
The Fault relay output will be activated.
If there are active alarms when isolation is invoked, the alarm relays on the Detector will restore and an
alarm-off message will be sent to an IIM.
