1 Overview Introduction The Series 24000 Microwave Intrusion Detection System is designed for exterior perimeter intrusion detection applications. The Series 24000 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 100 m (328 ft.) • Terrain must be level to grade, ± 7.6 cm (3 in.) • Terrain finished with crushed rock (2.5 cm {1 in.} max.
CYdU cU\USdY_^ Movement Movement of objects (trees, brush, shrubs, etc.) in the detection zone may cause the system to alarm. The detection zone should not include water, such as lakes, streams or ponds which, if moving, may result in alarms. Depending on the level of security desired, the presence of wildlife (rabbits, cats, dogs, deer, cows, etc.) may result in nuisance alarms. The motion of semi-rigid objects (metal buildings, fences, materials, etc.
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 24000 Intrusion Detection System is shipped in one carton. Immediately after unpacking, identify all components and report any shortages to Senstar-Stellar. The components in each carton are as follows: Transmitter unit Antenna enclosure assembly. Transmits microwave beam. Receiver unit Antenna enclosure assembly (see Figure 3-1). Receives microwave beam. Mounting hardware One set per unit.
D__\c Q^T UaeY`]U^d Wall mounting brackets Facilitates mounting the unit directly to a wall. Transit damage Although the transmitter and receiver are carefully packed, check for possible transit damage. If any damage has occurred in shipping, leave the packing carton and components intact and notify your carrier. Senstar-Stellar is not responsible for shipping damage.

This height chart is intended to furnish a preliminary mounting height only. The final operating height will be determined during electrical alignment and final adjustment.

It is recommended that primary power be brought to the base of each unit's mounting post and terminated in a weatherproof enclosure.
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 11 VDC, when the receivers are not in alarm (maximum current draw). Transmitter wiring Refer to Figure 3-4 for a wiring diagram of the transmitter unit. It is suggested that an installation wiring diagram be made before wiring the transmitter.

4 Operating instructions Once the following preliminary check, alignment, and sensitivity adjustments are accomplished, the Series 24000 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.
@bU\Y]Y^Qbi SXUS[ Sensitivity jumper The position of the Sensitivity Jumper is determined by the application requirements: • 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.
@bU\Y]Y^Qbi SXUS[ Antenna with 16 patches covered (11º) Antenna with 32 patches covered (16º) Figure 4-1: Antenna patterns Electrical alignment An electrical alignment requires the antennas of both the transmitter and receiver units to be aimed head-to-head. Verify initial mechanical alignment. Once this initial mechanical alignment is done, a more precise electrical alignment is required.
@bU\Y]Y^Qbi SXUS[ AGC measurement At the receiver, connect a digital voltmeter between TP-10 (+) and TB1-1 (-). This is the automatic gain control (AGC) voltage. After final alignment, as outlined below, the AGC voltage should be between 1.7 and 7.3 VDC. Put the SHORT-LONG jumper in the LONG position to increase the AGC voltage. Put the SHORT-LONG jumper in the SHORT position to decrease the AGC voltage. Receiver Slowly move the receiver unit up and down the post while monitoring the receiver AGC voltage.
@bU\Y]Y^Qbi SXUS[ Sensitivity adjustment Before beginning a sensitivity adjustment, make sure the receiver “ALARM” LED is not lit. Connect an ohmmeter between TB1 - terminals 10 and 11. It will read less than 0.5 ohms when the system is operational (armed) and infinity when the unit is in alarm. Leave the ohmmeter connected. Alarm test A preliminary alarm test requires walking across the detection zone to ensure the unit goes into alarm (“ALARM” LED lit, ohmmeter to infinity).
5 Troubleshooting The following are procedures for troubleshooting the Series 24000 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 24000 is very likely. Return for repair procedures A Return Material Authorization number (RMA) 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.
