4.2 MW Anti-Mask Indications
The MW anti-mask is activated if a validated detection of movement (both PIR and MW) has occurred, followed within the next 90n
seconds by a close MW detection without a PIR detection. This will cause the green frame to appear on the
OLED
screen for 90
seconds. The MW anti-mask relay has not yet been activated. If an alarm is triggered as the result of the main
lens’
detection of an
object, during that same period, the blue frame will disappear and a MW anti-mask event will not
occur
. If no alarm is triggered by
detection of the main lens in the 90 second period, a MW anti-mask relay will be
activated
and
the MW anti-mask logo will be
displayed. The MW anti-mask relay and logo will be cleared by an Alarm event triggered by the main lens.
An Active IR anti-mask has a higher display
priority. If Active IR and MW anti-mask events occur simultaneously, then the blue frame
will appear instead of a green frame and the Active IR anti-mask logo will appear instead of
the
MW anti-mask logo. The resulting
relays are not affected by the display
priority
.
MW anti-mask detection appears in Operational Mode after detection of a moving
object and 90 seconds have elapsed from the time the MW anti-mask Notification
was displayed. In test mode, MW anti-mask detection appears immediately on
detection of a moving object.
MW anti-mask notification appears in Operational mode only, immediately on
detection of a moving object for 90 seconds.
4.3 PIR and MW Indications
4.3.1 Pr
e-Alarms
When a movement signal is detected by within a PIR or MW range, the corresponding pre-alarm is
shown.
The detector waits for 16 seconds for the complementary technology’s detection. If no additional movement is detected during
that time, the detector will return to its standby
state.
