Vedard Security Alarm Technical Support

PIR and MW outdoor intruder detector has strong ability of anti environment interference.
FT-89R has more functions of anti-mask, tamper-resistant, 3-dimensional protection area with 12m*12m wide angle.
There is FT-89SR solar power wirless type as well.
Enterior security is important and essential for residential security, commercial security and industry security.
So, many types enterior security equipment, perimeter security alarm device, detection systems are designed for the purpose.
There are two types of outdoor security equipment. One is beam system which covers an invisible barrier for entrance protection such as garden, yard, farm. Another is PIR and MW double technology Intrusion Detector for a detection area such as 12m *12m.
These two types enterior security equipment can be used according to protection area feature and needs. And they can be combined used as well. Focus alarm Meian tech security system outdoor wireless burglar alarm. Easy installing professional security systems for complete home security.

Passive infrared detector PIR is a type of weak signal detection equipment. There are some notices for attention when install it. For example, the installing height and sensitivity are two key points for attention. There are three steps to prepare and install a PIR detector.
Step 1: Well understand the performance characteristics of the PIR detector.
Step 2: Correctly determine the location for PIR detector installation.
Step 3: Carefully adjust and debug the infrared detector.
Below is the details for attention.
A. Installing location:
1. Determine the correct installing height and angle according to PIR installing instruction manual and using requirement, environment. The protection area, sensitivity and pet immunity effectiveness is different with different installing height. Find out the entrance and exit of the building and intrusion routine, install the detectors at places to cover the areas.
2.Do not install the PIR detector facing glass doors and windows.
PIR detector can anti interference of white light but not 100%. And outdoor passing people and vehicle may cause false alarm. PIR and MW double technology detector can be installed at this place without interference.
3. Do not install the PIR detector facing cold and hot air outlets or cold and heat sources.
PIR detector senses object’s temperature change and triggers alarm. So the air flowing from cold or heat outlet may cause false alarm. If you have to install the detector at these places, you can choose PIR and MW double technology detector.
4. Do not install the PIR detector facing a swinging object. A swing object may cause false alarm by Microwave detector as well. B: Detector choosing and debugging
1.Correct choosing of detector.
There are various types of PIR detector. They are wide angle PIR or curtain PIR with 6m to 60m detection distance, infrared sensor or Microwave sensor, wall mounted or ceiling mounted. It should be correctly chosen according to protection space, intrusion routine characteristics, environment features.
2.Debugging
Debugging is absolutely necessary work after installing of motion sensor. There are two ways for debugging. One way is walking test. The test person walks in the protected area with S routine to check the protected area. The microwave sensor sensitivity and PIR sensor sensitivity should be adjusted separately. Sometimes the sensitivity should be adjusted again in different season. Microwave has penetrability and the sensitivity can not be set too high.
Another way is using instrument to measure. Some detector has noise voltage output interface. Using a multiple meter to measure the noise voltage and adjust the sensitivity.

PB-205R is Focus brand wireless convertor. It is used for the long distance transmission in the enrironment of strong obstancle. It can amplify the signal to the panel. Up to 60 detectors signal can be transmitted. It has tamper resistant switch for itself security.
It is AC power supplied with backup battery.
