1 System planning The μltraWave Microwave Detection Sensor is designed for exterior perimeter intrusion detection applications. μltraWave consists of a microwave transmitter and receiver, which detect motion in a defined area (see Figure 1). The transmitter sends microwave signals to the receiver, and any motion in the detection zone causes a variation in the received signal strength.
Site planning & design Site planning Conduct a site survey in which you note the physical features of the zone and surrounding area. Include accurate measurements on a detailed drawing. The following is a list of rules to follow when planning a microwave zone: • Line of sight - A direct, unobstructed line of sight is required between the transmitter and receiver. • Depressions and deviations in terrain - Drainage ditches and gullies must be avoided or filled in.
Site planning & design Zone placement The μltrawave system requires a long, flat, detection zone free of obstacles and depressions. The minimum distance between the beam centerline and any object (fences, buildings, vehicles, trees, bushes, shrubs, etc.) is outlined in Table 1. Separation distances are based on typical conditions and can vary depending on site conditions including zone length, unit mounting height, ground cover, type of obstacle, etc. The following separation distances are minimum values.
Site planning & design Microwave offsets The areas immediately above and below the transmitter and receiver antennas are not exposed to the microwave energy. A microwave offset is used to prevent this unmonitored area from being vulnerable to undetected intrusions (see Figure 2). Offsets prevent intruders from crawling under or jumping over a microwave unit to gain undetected access to the protected area.
Site planning & design Mounting heights The recommended method for determining the μltraWave unit mounting height is to use the UCM design tool. However, the mounting height chart (see Figure 4) can also be used to determine the optimal mounting height for the transmitter and receiver. The horizontal axis of the chart represents the separation distance between the transmitter and receiver.
Site planning & design Power and ground requirements The μltraWave sensor system consumes 4 W maximum. Both the transmitter and receiver can operate on a wide range of input voltages (12 to 48 VDC). The required gauge of the power cable depends on the power supply capacity, the number of μltraWave units being powered and the lengths of the power cable runs. In locations where AC power may not be stable or reliable, an uninterruptable power supply (UPS) should be used for primary power.
Site planning & design Relay contact ratings The dry contact relays are single pole, double throw, Form C, latching, rated for 30 V @ 1 A max. In Remote control mode, you can configure the relays as latching (ON by command, OFF by command), in flash mode (ON-OFF-ON-OFF, etc. by command, then OFF by command), or pulse mode (ON for a period, then OFF). For flash and pulse modes, the relay Active/Inactive times are selectable.
Site planning & design Senstar recommends hiring a local fencing contractor to install the μltraWave mounting posts. Note Foundation The foundation for the mounting posts in normal soil should be at least 91 cm (3 ft.) deep and 61 cm (2 ft.) in diameter. If soil conditions are such that a non-shifting foundation is questionable, then a larger footing is required. In areas where ground freezing can cause frost heaving, use a truncated pyramid base foundation.
2 Installation The μltraWave transmitter and receiver units are almost identical, with only minor differences in component layout. Figure 7 shows an μltraWave receiver and illustrates the unit’s features. The receiver’s diagnostic activity LEDs are listed in Table 2 .
Mounting the µltraWave units Mount the transmitter and receiver units on their respective posts, using the hardware provided in the post-mounting kit (p/n E4KT0300, see Figure 8 ). The mounting height of the transmitter and receiver units is measured from the center of the antenna to the ground’s surface. As an alignment aid, the cover over the antenna includes an embossed X-pattern, that indicates the center of the antenna.The μltraWave units can also be mounted on a wall or other flat stable surface.
Figure 9 Post-mounting procedure Post-mount alignment For optimal performance, ensure that the μltraWave transmitter and receiver are aimed directly toward each other, and that the mounting height is correct for both units (see Figure 10 ). 1. Measure and verify the mounting heights of both units. 2. If required, loosen the transmitter’s gear clamp slightly, and then carefully aim the transmitter directly at the receiver. 3. Tighten the transmitter’s gear clamp. 4.
horizontal adjustment vertical adjustment Figure 10 µltraWave alignment Surface-mounting CAUTION For surface mount applications, the two mounting surfaces must face toward each other. Surface mounted μltraWave units cannot be rotated in the horizontal axis. If required, use shims to adjust the horizontal alignment of surface mounted units. The μltraWave mounting bracket can be used to surface mount the transmitter and/or receiver.
2. Using an 11 mm (7/16 in.) wrench and the supplied hardware (bolt, lock washer, flat washer X4) attach the post collar to the mounting bracket with the flat side of the collar to the outside. post collar mounting bracket Figure 11 µltraWave alignment 3. Hold the μltraWave unit against the mounting surface and measure the mounting height of the unit from the center of the antenna to the ground’s surface (see Figure 8 ). Mark the mounting surface at the centers of the two slots in the post collar. 4.

Making the I/O wiring connections 1. Pull the data cable into the enclosure. 2. Prepare the data cable - strip length = 6.4 mm (0.25 in.). 3. Remove the terminal block from T6, make the wiring connections, and then replace the terminal block (see Figure 12 ). Enclosure tamper switch Each μltraWave unit includes a mechanical tamper switch (closed = secure, open = tamper) to indicate if the enclosure cover is removed. Placing a shunt on header T2 overrides the tamper switch (shunt ON = secure).
Silver Network wiring connections A network interface card must be installed on the μltraWave receiver to enable network communications.

3 Setup and calibration μltraWave setup and calibration is done using Senstar’s Universal Configuration Module (UCM). The UCM is a window-based software application that performs the calibration, setup, maintenance and diagnostic functions for Senstar’s line of intrusion detection sensors. The UCM connects directly to the μltraWave unit via USB. Network based μltraWave receivers can also connect remotely via the Silver Network Manager.
Setup Setup μltraWave setup and calibration must be performed by a qualified technician. Note Connecting the UCM 1. Remove the lower cover from the μltraWave enclosure and use a USB cable to connect the UCM computer to T2 on the transmitter PCB. 2. Start the UCM application and establish a connection.
Setup Setting the transmitter/receiver Frequency Pair Note Both the transmitter and receiver must use the same Frequency Pair. If there are other nearby μltraWave sensors, they must be set to different Frequency Pairs. 1. Connect the UCM to the transmitter unit. 2. On the μltraWave main menu, select the Config tab. 3. In the Frequency Pair field, use the arrows to specify the Frequency Pair that will be used for this μltraWave sensor (transmitter and receiver). 4.
Setup Specify the Auxiliary I/O control mode This section details the procedures for configuring the outputs and input for Local control and Remote control operation. 1. Select the Aux Cfig tab. 2. Use the Aux Control arrow to specify the control mode (Local or Remote). 3. Select the Download button to save the configuration changes to the μltraWave unit.
Setup Input configuration procedure (Remote control mode) 1. Select the Aux Cfig tab on the UCM window. 2. From the Supervision drop down, select the desired supervision scheme for the input. 3. Select the Resistor 1 value, if applicable. 4. Select the Resistor 2 value, if applicable. 5. Set the Noise Tolerance, if required. 6. Set the Line Drop, if required. 7. Set the Filter Window. 8. Save the UCM configuration file. 9. Select the Download button to save the configuration changes to the receiver.
Receiver calibration Setting the receiver’s address The receiver address can be set only by using a direct USB connection between the UCM computer and T3, the USB port on the receiver. Systems that do not use network communications can use the default address of 1. 1. In the Program field select the Address button. The change Device Address dialog displays. 2. In the Change Device Address dialog, specify the New Address for the connected receiver. 3. Select the Program button.
