SERVICE UPON RECEIPT AND INSTALLATION
Note. Installation and checkout operations applicable to the MWS are assigned to the intermediate (direct support) v by
the maintenance allocation chart. Therefore, this chapter is applicable only to that level of maintenance
Section I. SYSTEMS PLANNING
a. Planning for J-SIIDS installation will include installation of the MWS.
b. J-SIIDS installation layouts will accommodate the special considerations applicable to the MWS (para 2-2) c.
For the purpose of this manual, it is assumed that all operations preparatory to connecting the MWS to the J-SIIDS
Control Unit will have been accomplished. Since the electronics of the MWS require 20 + 1 vdc power from the J-SIIDS
Control Unit for proper functioning, it is further assumed that the J-SIIDS Control Unit will be operational.
2-2. Special Considerations
a. The MWS Signal Processor Unit (SPU) must be located as close as possible to the nearest protected weapons
rack. Three mounting holes are provided in the back surface of the SPU chassis. These holes will accommodate 5/16
inch diameter screws (or studs). Characteristics of the walls in some arms rooms may necessitate the use of toggle-bolt
or expansion-sleeve type fasteners. Use of a mounting panel may be required.
b. The SPU will be interconnected with the J-SIIDS Control Unit by 1/2 inch rigid electrical conduit. Conduit should
be installed, and hookup wires pulled, prior to starting installation of the MWS.
c. Wires from the J-SIIDS Control Unit must be long enough to permit easy hookup to the SPU. They should not be
so long as to interfere with or be damaged by the SPU cover. Unless specified otherwise in the J-SIIDS system-level
manual, these wires will be terminated with solderless, crimped terminals.
d. Between weapon racks, loop sensor wires (twisted pair) may have to cross aisles. In such instances, the wires
will have to be secured against movement (which could cause false alarms) The wires should also be shielded from
physical damage due to pedestrian or equipment traffic.
e. The overall length of a loop sensor will be something less than 500 feet (1000/2 minus transposition allowances).
In some instances, loop sensor configuration, weapons rack arrangement, or both, may have to be altered.
Section II. SERVICE UPON RECEIPT OF MATERIEL
a. The MWS will be packaged, packed, and shipped by the manufacturer in accordance with best commercial
b. Aside from normal handling precautions, no special unpackaging instructions are applicable to the MWS.
2-4. Checking Unpacked Equipment
a. Inspect the equipment for damage incurred during shipment. If the equipment has been damaged, report the
damage on DD Form 6 (Report of Damaged or Improper Shipment) as prescribed by AR 700-5 Note. The MWS cannot
be placed in service if any item is missing.
b. Check the equipment received against the packing slip to see if the shipment is complete. See figure 1-1 if there
is no packing slip. Report all discrepancies on DD Form 6.
c. Check to see if the equipment has been modified. (Equipment that has been modified will have the MWO
number on the inside of the SPU cover near the identification plate.) Check also to see if all currently applicable MWOs
have been applied. (Current MWOs applicable to the equipment are listed in USASA PAM 310-6 or DA PAM 310-7, as
