Normally Energized: The Normally Energized or Normally De-Energized setting of each relay can be
configured using the checkbox in the Normally Energized row:
If checked the relay is set Normally Energized.
l
If unchecked the relay is set Normally De-energized.
l
In the Normally De-energized mode no drive is applied to the relay coil until the assigned condition such as
Alert or Fire 1 occurs. The Normally Energized mode is the opposite. Drive is removed from the relay coil
when the condition occurs.
The default mode of the relays is listed in Table 4-2.
Latching: If the cause of a condition is removed (for example, smoke decreases below the threshold) and
latching is enabled, the detector "remembers" the condition and holds the corresponding relays and displays in
the active state as though the cause of the condition were still active.
Latching can be enabled for any alarm condition or for urgent or minor fault by checking the corresponding
latching checkbox to the right of the condition.
Beep: The detector's buzzer can be configured using the checkboxes under heading "Beep". If checked the
buzzer will beep when the condition occurs.
