Viewguard Series DUAL
1.
Introduction
The Viewguard DUAL motion detector comprises two systems that operate fully
independently: Passive infrared detector plus Microwave detector. The functioning principle
of the detector is based on the intelligent linkage of a passive infrared sensor and
microwave. This type of linking renders the detectors particularly insensitive to air and
thermal turbulences. (Microwave module see Fig.
They are delivered with the following main features:
5
-
Volumetric mirror optic
(see Fig. 3- , Fig. 6)
-
Anti-masking up to 30 cm from the detector
-
Microwave sensor inactive in the "disarmed" state.
-
FAI (First Alarm Indication):
When multiple detector on a single zone, Indicate the first detector in alarm

Installation Guide line
Maximum sensitivity is achieved when mounted crosswise to the horizontal detection
zones of the PIR sensors. Therefore, select a mounting site that runs crosswise to the
expected direction of motion. (See Fig.
6-A
Due to the additional microwave, the dual detector has a very high detection capacity even
with diagonal movement. (See Fig. 6-B).
Minimum distance to ceiling: 2 cm
Avoid:
* Mounting above radiators
* Mounting near air discharge openings (e.g. air conditioning systems)
* Direct sunlight
* Mounting near to fluorescent lamps
* Mounting near to light bulbs

Installation
Open housing
(see Fig. 1)
If necessary, break the seal with a small screwdriver or similar object and pull downward
1
. Press the notch (at the bottom in the middle, see Fig.

press off the front of the housing
. Lift off the housing front
Mounting options
• 0° Vertical
• Vertical at a 3° downward angle
• Horizontal at a 45° angle to the left or right
• Corner mounting
The detector can be mounted by using the optional swivel bracket (see "Accessories").
Recommended mounting height 2.5 m for optimal operating sensitivity.
If the detector is not mounted at the recommended mounting height, this will have a negative
effect to the monitored area. In this case please get in contact with our technical support.
Carry out a walk test for each detector in all cases

Backtamper
(see Fig. 4)
Required for installation according to EN 50131-2-4 grade 3.
The backtamper can be used if installed as illustrated in Fig. 5/1, 5/2, 5/3a, 5/3b and 5/4.

Note:
In this operating mode no alarm indication is available.

Anti-Mask function always active
Minimum of required connections: Alarm output and operating voltage (= 4 wires).
The usage of the "Walk test" input is optional. The detector is automatically in walk test mode
for 10 minutes after applying the operating voltage (see 6.2 and 6.3).
