1 Overview Introduction The Series 14000 Microwave Intrusion Detection System is designed for exterior perimeter intrusion detection applications. The Series 14000 detects movement within a microwave field between the Transmitter and Receiver and initiates an Alarm to alert responding personnel. General description The Senstar-Stellar Microwave Intrusion Detection System consists of a microwave transmitter unit and receiver unit.

2 Site planning & design NOTE: Refer to Appendix b, Application notes for additional information on microwave site planning and design. Site preparation The amount and type of site preparation required depends on the level of security desired. The physical specifications for a high security detection zone are: • Transmitter/receiver separation distance no longer than 122 m (400 ft.) • Terrain must be level to grade, ± 7.6 cm (3 in.) • Terrain finished with crushed rock (2.5 cm (1 in.) max.
CYdU `bU`QbQdY_^ Line of sight A clear, direct line-of-sight between receiver and transmitter unit must be maintained at all times. The sensor system will work best in a long, flat, detection zone. Movement Movement (trees, brush, shrubs, etc.) in the detection zone will cause the system to alarm. The detection zone also should not include water, such as lakes, streams or ponds which, if moving, may result in unwanted alarms.
CYdU TUcYW^ Site design Detailed site design drawings for the microwave sensor system should be prepared as soon as possible after the site survey. Dimensions and elevations should be shown on these drawings, as well as the location of the physical objects noted during the survey. After the site drawings have been completed, the next step is to plot each microwave zone. Zone placement, zone length, and offsets are essential to the design of a reliable microwave security system.

3 Installation Unpacking and inspection The Series 14000 Intrusion Detection System is shipped in two cartons. Both cartons are packed identically, with the transmitter unit being in one and the receiver unit in the other (see Figure 3-1). Immediately after unpacking, identify all components and report any shortages to Senstar-Stellar. The components in each carton are as follows: Transmitter unit Parabolic antenna and weatherproof electronic enclosure. Transmits microwave beam.
D__\c Q^T UaeY`]U^d 10-Line RFI filter Provides filtering for radio frequency interference. Power distribution box Provides convenient wiring interface between units and alarm reporting panel. Tamper switch and 115 V outlet receptacles are available. Power supply with standby battery Plugs in to 115 VAC outlet, provides 2 A continuous power with 5 AH standby battery. Transit damage Although the transmitter and receiver are carefully packed, check for possible transit damage.

The mounting height of the transmitter and receiver units is measured from the center of the parabolic antenna to ground. Refer to Determining mounting height on page 3-6 for the approximate mounting height of the microwave units. For high security applications mount the units at 61 cm (24 in.) centerline to ground.

4UdUb]Y^Y^W ]_e^dY^W XUYWXd Node curves The node curves (N1, N2, N3 and N4) represent the pivot point for coordinating distance (horizontal axis) to mounting height (vertical axis). Those mounting height and distance coordinate lines that meet in the area between the node curves should be avoided. Coordinate lines that meet on the node curves are preferred because they will result in higher signal strength at the receiver and a wider fade margin.

DbQ^c]YddUb gYbY^W CAUTION: When using one DC power supply to power more than one system, insure the wiring between the power supply and the unit is sufficient to prevent the input voltage at the unit from dropping below 11VDC. Transmitter wiring Refer to Figure 3-5 for a wiring diagram of the transmitter unit. It is suggested that an installation wiring diagram be made before wiring the transmitter. This will standardize the wiring of transmitters in a multiple system installation.

4 Operating instructions Once the following preliminary check, alignment, and sensitivity adjustments are accomplished, the Series 14000 Intrusion Detection System is ready to operate. There are no controls or indicators for operating the sensor system, and no alternate operating modes during emergency conditions. Preliminary check Once the system is mounted and wiring installation completed, a preliminary check is recommended before applying power to the system.
@bU\Y]Y^Qbi SXUS[ Sensitivity jumper The position of the Sensitivity Jumper is determined by the application: • L = Low Security • M = Medium Security • H = High Security (See page 2-1 for definitions of these terms.) This jumper effectively reduces the maximum alarm sensitivity, preventing excessive sensitivity that may result in nuisance alarms. Electrical alignment An electrical alignment requires the parabolic antenna of both the transmitter and receiver units to be aimed virtually head-to-head.
@bU\Y]Y^Qbi SXUS[ Final alignment Before securing the mounting hardware, repeat the transmitter and receiver unit electrical alignment steps for obtaining maximum AGC reading on all rotational axes. Secure hardware Secure the mounting nuts and parabolic-to-enclosure bolts. Ensure the AGC voltage remains high after the hardware is tightened. Put the timed-latched jumper (white wire) into the “timed” position.
@bU\Y]Y^Qbi SXUS[ High security zone Adjustment for a typical high security application requires the detection of a prone human crawling through the detection zone with the length of the body parallel to the line of sight. A 30.5 cm (12 in.) metal sphere (see tools on page 3-2) represents approximately the same target to the microwave sensor. When adjusting the sensitivity to high security specifications, slowly (2.4 cm {1 in.
5 Troubleshooting The following are procedures for troubleshooting the Series 14000 Intrusion Detection System. If, after checking out these conditions, you find your system is still not functioning, then the possibility of a faulty condition on another system on the premises besides the Series 14000 is very likely. Return for repair procedures A Return Authorization number must be obtained from Senstar-Stellar before any items will be accepted for return.
Troubleshooting Test points The boards containing the electronic circuitry in the transmitter/receiver unit enclosures may be tested for readings required for normal operation of the system. Figures 5-1 (receiver) and 5-2 (transmitter) show the location of the test points on the boards. These tests should be done under the following conditions: 1. 12 VDC (nominal) power applied to both transmitter and receiver units. 2. The same channel selection for both transmitter and receiver. 3.

Bistatic microwave sensors have been used in security applications for many years.

Figure 4: Top View- Intermediate Overlap The detection coverage is largest midway between the transmitter and receiver.

E6DA0109-001, Rev A page 3 Site Rules - DO’s and DON’Ts • DO use bistatic microwave sensors in clear, flat areas that provide a clean line-of-sight. Bistatic microwave units are line-of-sight sensors that require a reasonably long and flat detection zone.
page 4 E6DA0109-001, Rev A • The detection zone must be completely free from vegetation, for the full width of the microwave pattern. • Perform all routine site maintenance, as required. 2. Check the alignment. For Intelli-WAVE, if the received signal is adequate (LED 6 or greater on the alignment aid, or a voltage measurement of 2.5 VDC at tp6 and tp12) the selected mounting height is correct.
Intelli-WAVE & Series 14000, 16000 and 24000 Microwaves Application Note #2 September 27, 2002 E6DA0209-001, Rev B Stacking bistatic microwave units Introduction help prevent interference between the two sets of microwave units. Bistatic microwave sensors have been used in security applications for many years. Typically, microwave sensors provide a detection zone with a limited height.
page 2 5. 6. E6DA0209-001, Rev B For multiple zone configurations, carefully plan the layout, ensuring that there are no possible conflicts or interference in modulation frequency or polarization. Use a minimum 10 cm (4 in.) post to ensure stability. Each post must be installed in a concrete base that is at least 61 cm (24 in.) in diameter and either 91 cm (36 in.) deep, OR, 15 cm (6 in.) below the frost line, whichever is greater.
