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 all

variations and all frequencies.

The PEWS is available in six different operatingfrequencies. The variat 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.

a) 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.).

TYPICAL PEWS CAPABILITY



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

Maximum distance from Detector to Receiver is1500 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 should



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

When emplacing detector, observearrow and note on detector case.

When detecting vehicles, the detectormust be aligned so that arrow

is parallel to expectedtravel of vehicles.



TM 11-5895-1047-10

• Pack soil firmly against sides of detectorcase. Do not cover top of detector case.

• If detector is to be used in wire mode, strip in-sulation from ends of field wire with wire cut-ters.

• Insert each wire end into terminal posts ondetector by pressing down top of post in-serting wire into post

Ž Run field wire to receiver location;camouflage as necessary.



TM 11-5895-1047-10NOTE

Detector antennas are NOT required for wiremode of operation. Do NOT allow any plants or

other objects to touch detector antenna or datapost.

Turn detector on - set RF-OFF-W switch to RF(for radio mode) or W (for wire mode).

Camouflage detector as necessary.

Repeat the above steps for installation ofother detectors.



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

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 connected
