HOW TO USE THIS MANUALThe variation number appears following the (V)

in the equipment nomenclature. The variationnumber is used to identify the operating frequencyof the Detectors and Receivers. All of the Detec-tors and Receivers, which operate on the same fre-quency, have the same variation number.

In this manual, when official nomenclature isused but operating frequency is not important, thevariation number will not be used. For example,when you see AN/TRS-2(V) without a numberfollowing the (V), you will know that it means allvariations and all frequencies.

1-8. DIFFERENCES IN EQUIPMENT.

The PEWS is available in six different operatingfrequencies. The var ia t ion number in thenomenclature is used to designate the operatingfrequency.

Detectors and receiver variation numbers must bethe same.

1-9. TECHNICAL PRINCIPLES OFOPERATION.

SYSTEMThe AN/TRS-2(V) has two modes of operation, an

RF mode and a wire mode. In the RF mode, detec-tor DT-577(V)/TRS-2(V) detects the presence of anintruder and determines the type of intrusion (per-sonnel or vehicle). The detector then transmits acoded signal to Receiver R-1808(V)/TRS-2(V). Thesignal is processed by the receiver which pro-duces an audible tone, digital display or both,identifying the detector that is sensing anintrusion.

In the wire mode the detector is connected tothe receiver via field wire using Wire Link MX-9738/TRS-2(V). The wire link provides for connec-tion of up to nine detectors to a single receiver.Received signals are processed in the same man-ner as described for the RF mode.

CHECKS AND SERVICES

2-4. GENERAL.

To be sure that equipment is always readyfor your mission, you must do scheduledpreventive maintenance checks and ser-vices. (PMCS).

PMCS TABLE

There are three categories of PMCS: B, D, and A.They are at the top of the INTERVAL column of thePMCS table. A check mark in one or more of theINTERVAL columns indicates the check and/orservice that you should perform at a particulartime.

a. B means before. B-PMCS is performedBEFORE operation to make sure that thesystem is ready to work.

b. D means during. D-PMCS is performed DURINGoperation.

c. A means after. A-PMCS is performed AFTERoperation.

2-5. ROUTINE CHECKSRoutine checks consist of cleaning and dusting

checking for damaged equipment and missingparts. These are things you should do anytime yousee they are required. Routine checks are notlisted in the PMCS table.

2-8. SYSTEM PLANNING AND INSTALLATIONa) Installation Planning

(1) System Planning

The PEWS will be installed in accordance withparticular security requirements of a site.

Site Considerations:

Size of area to be protected (How manydetectors you will need).

Type of terrain.

Type of soil in area.

Noise level in area.

Tactical considerations (whether there arepaths or roads to be monitored, location ofcamp site etc.).

2 RECEIVER POSITION

TYPICAL PEWS CAPABILITY

2-26

TM 11-5895-1047-10● Size of area.Maximum detection range of each detector is a 10meter radius.

Maximum distance from Detector to Receiver is

1500 meters.

(2) Transmission Path Planning

Effective operating ranges will be less if there isnot a CLEAR PATH between the detector andreceiver (RF mode).

Terrain should be level as possible or receivershould be elevated above detectors (RF mode).

FIELD WIRE should be laid where it will not bedamaged by rocks or other hazards (Wire Mode).

FIELD WIRE should be camouflaged as much aspossible.

(3) Detector Site and Layout

PEWS will be used to provide early warning toriflemen and weapons positions.

Areas where there is no Clear Path should benoted. These are areas where trees, rocks, hills,etc. block your view. In general, detectors shouldbe installed in areas where you cannot see enemyapproaching.

2-27

TM 11-5895-1047-10b) Installation of Detectors

After choosing detector sites, install as-sembled detectors.

• Dig shallow hole at detector location aboutone inch deep, slightly larger than detector.

Ž Sketch out the location and ID numbers ofeach detector you install to be sure that youhave fully covered area to be protected. Youmay sketch on the writing area located on thereceiver.

NOTE

TM 11-5895-1047-10c) Optional Use of Detectors in Wire Mode.

For quick set-up of detectors, or special tac-tical situations, detectors may be set-up so thatonly one field wire pair is required to connectseveral detectors. This is called Hot-Loop.

l Field wire IS run to first detector in Hot-Loop group. Other lengths of field wire connect other detectors with each other in“Parallel”.

Using screwdriver, connect one pair of wiresfrom each detector to numbered terminal onwire link (installed on receiver).

Using screwdriver, connect wire lead fromground rod to GND terminal on wire link.

Push ground rod into soil in area wherereceiver is to remain operating.

CAUTION

Grounding rod should always be connectedto the wire link during operation to prevent elec-

• To operate PEWS, set DPSL-TONE-OFF switchto either the DPSL or TONE position.

• When intruder is detected the display win-dow will indicate alarm in the DPSLposition. In addition a tone will be heardin the headset.

Ž For tone operation only, set the switch tothe TONE position. When an intruder isdetected tone will be heard in headset

NOTE

Use TONE position to conserve battery duringlong periods of monitoring.

If battery is low, an “L” will be displayeddisplay window even if TONE position isselected.

2. Display should then clear.You can check receiver for proper display or low

battery at any time during operation by using TESTRESET but ton. Press but ton in and ho ld ;

3. When detector senses intruder, message issent to receiver.

Detector ID number appears on receiver display.

Intruder classification displays (P = personnel,C = vehicle).

Decimal points will always light when a new in-trusion is displayed.

Tone will sound in headset.

4. Information is stored in receiver memory.

When new messages from other detectors arereceived, they will be momentarily displayed onreceiver with decimal points and tone.

When no new messages are being received,previously received (old) messages (withoutdecimal points) are repeated in display window inrotation (starting with lowest number).

2-35

TM 11-5895-1047-10

If both personnel and vehicle intrusions aredetected, they will both be displayed and repeatedin rotation, starting with the lowest detector IDnumber.

Turning DSPL-TONE-OFF switch to TONE willmake display go blank, but will not erase receivermemory.

To erase memory, press TEST RESET button on receiver.

5. If you see the same ID numbers (withdecimals and audio alert) displayed morethan once, there may be more than one in-truder near detector.

2-36

TM 11-5895-1047-10Detecting an intruder (TONE position).

Operation in TONE position is the same as inDSPL position, except that no display will ap-pear in WINDOW.

If tone is heard in headset while monitoring forintruder, turn DSPL-TONE-OFF switch toDSPL position.

ID number and classification of intruder will ap-pear on display.

Any messages stored in receiver memory will bedisplayed in rotation.

Switching from DSPL to TONE or TONE to DSPLwill not erase receiver memory.

Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it. Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it... They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
