| Voice Recording / Warning
Functions ( VX-402REC
only ) |
| The VX-402REC provides great flexibility in
detector-activated voice applications. As well as the
ability to record any message in any language, with its
superior playback settings, it allows the right message
to be played in every situation. |
|
 |
Easy Voice Recording
|
|
| By using either the built-in microphone or external
recording equipment such as a PC, the VX-402REC allows two
messages of up to eight seconds to in length to be recorded.
|
|
|
|
Voice Warning Function
|
|
|
|
| When the VX-402REC first detects someone
in the area, it delivers a caution message.
If someone is detected in the same area a
second time within 30 seconds of the first
message being given, it is repeated. On a
third detection within 30 seconds, the
caution message automatically changes into a
warning message. |
|
|
|
|
|
| When the VX-402REC is used with another
detection device such as an outdoor PIR,
active photobeam or a magnetic contact,
different messages can be set to make double
sure intruders are deterred. The caution
message is generated at the first detection,
and the warning message generated at the
second detection. |
|
|
|
|
|
| Changes the message automatically in
daytime and nighttime, for example giving a
welcome message in daytime and an alert
message at night. |

External Speaker
Terminal |
|
The VX-402REC has a voice output terminal
allowing an external speaker to be connected. The most common
applications for this are either when a high-volume announcement
is needed or when the best position for the speaker is away from
the detector unit.
|
|
A
Variety of Applications |
- Intruder Prevention: An alarm is
activated when an intruder enters
the property or prohibited area.
- Warning Alert: A safety warning
is activated. For example, when
children go near a dangerous area
such as a swimming pool.
- Shop Entrance: A welcome message
is given when customers enter a
premises.

|
|
| The VX-402 Series utilises Multiple Detection
Pattern Technology two double-layered detection patterns
(upper and lower) both have to be activated to generate
an alarm condition. This reduces false alarms,
particularly those caused by temperature changes, light
reflection and small animals. |
|
|
|
Flexible Detection
Range Function |
|
| By limiting the detection range, false alarms due
to unwanted movement, e.g., cars, people or animals outside the
protected area can be reduced. |
|
|
|
|
Size Judging Function |
|
|
The size judgment function virtually eliminates
false alarms due to small animals.
|
|
|
|
|
| When only the lower zone detects a
moving object, the unit is not activated. |
When only the upper zone detects a
moving object, the unit is not activated. |
When both the upper & lower zones
detect a moving object, the unit is activated. |
|
|
|
|
|
Advanced Temperature
Compensation |
|
| At higher ambient temperatures, the difference
between the background temperature and that of a human
body is reduced. In such cases an ordinary PIR might
fail to accurately detect the human body. The VX-402
uses advanced temperature compensation to automatically
increase the detector's sensitivity under high
temperature conditions, especially where the background
temperature ranges from 35-37?C, close to that of the
human body. |

|
Double Conductive
Shielding |
|
| Patented Double Conductive Shielding
Technology utilises a special conductive filter to cover
the element window, allowing infrared energy to pass
through, while blocking and grounding out unwanted light
and RFI sources. This helps reduce false alarms caused
by car headlights and reflected sunlight in particular. |
 |
|
|
|
Multiple Detectors for Improved
Functionality |
| For advanced functionality
and reliability without the need
for a control panel, the VX-402
can be connected to another
detector, e.g. PIR, photobeam or
magnetic contact. Various
configurations are possible.
|
|
 |
Wiring two VX-402 series
sensors together and selecting
the "OR"Mode enables the
detection pattern to be
effectively doubled.
|
|
 |
| By selecting the "AND" Mode
and programming which sensor
should be activated first (using
DIP Switch Programming), the
VX-402 Series can sense
direction and will only be
activated if motion is in a
specified direction. |
