The Passive Infrared (PIR) Sensor provides thermal indoor/outdoor motion of intruders within detection area. This Sensor is passive, non-contact type sensor and is designed to operate with battery power supply. Microprocessor signal processing is using for adaptive threshold adjustment and reduction of false alarms. The PIR Sensor is equipped with wireless module for transmission of alarm signal.
The PIR Sensor can be used as a module of monitoring perimeter systems for military, industrial, nuclear and civil installations. The combination of PIR Sensor with Seismic Sensor filed increases the probability of object detection. The PIR sensor can be used as part of the larger sensory system or as a standalone devise.
PASSIVE INFRARED (PIR) SENSOR MAIN COMPONENTS
The set of the PIR comprises:
1. Sensor Unit – 1 pc
2. Stand holder 2 pieces – 1 for the Transmitter and 1 for the Receiver Unit
3. Battery 2 pieces – 1 for the Transmitter and 1 for the Receiver Unit
STORAGE AND TRANSPORTATION
PIR composite parts can be stored in unheated storehouses and in field conditions in transportation packing. In field conditions it is necessary to use underlying surface or grate.
Mine composite parts can be transported by any kind of transport.
OPERATING INSTRUCTIONS FOR MWB
Mounting: Bringing MWB in armed state is performed after the two stand holders are placed at distance of 120 m from each other. The microwave transmitter unit is mounted at the first stand holder by using three screws. After mounting the transmitter unit at the first stand holder the unit is powered by connecting it to the battery as shown in fig. 4. The microwave receiver unit is mounted at the second stand holder by using three screws. After mounting the receiver unit at the stand holder the unit is powered by connecting it to the battery. When the battery connection procedure is conducted properly, a photo indicator must light in red or blue.
After several second the photo indicator must turn off which shows that barrier has self-adjust to the current levels of the microwave beam.
To reach the maximal distance coverage the transmitter and receiver units must be mounted at equal height above the ground and directed coaxially to each other.
MOUNTING ALGORITHM
Microwave receiver modulus mounting:
1. Stretch stand for fixing the Microwave Receiver Modulus.
2. Mount the Microwave receiver modulus to the stand, by screwing the 4 screws as it is shown in the figure.
3. Plug the battery to the receiver modulus and drop it inside the groove of the stand as it is shown in the figure.
4. Move our hand Check for the presence of light indicator on the back panel.
Microwave transmitter modulus mounting:
1. Move away up to 120 meters from the place where you mounted the Microwave Receiver Modulus.
2. Stretch stand for fixing the Microwave Transmitter Modulus.
3. Mount the Microwave transmitter modulus to the stand, by screwing the 4 screws as it is shown in the figure.
4. Plug the battery to the transmitter modulus and drop it inside the groove of the stand as it is shown in the figure.
5. Mount the Microwave transmitter modulus so that its front panel is targeting directly the Microwave Receiver Modulus front panel. The good targeting is a guarantee for good coverage.
Microwave beam check: To ensure that the barrier units are mounted properly and the system is working correct should observe the photo indicator at the back side of the receiver unit while some object or person is crossing the microwave beam near to the transmitter unit. If the photo indicator turns red or blue it means that the barrier is working properly.
If the photo indicator doesn’t change its condition (stays dark) you should check the battery connection and/or readjust the direction of receiver and transmitter units to each other. Then repeat the check.
Radio communication check: Each time when the photo indicator at the back side of the receiver unit is lighting in red or in blue the unit sends a message to the command post radio unit.
