1 Introduction
1.1 General Description
This PAL-AT®Installation Manual is intended for use as a general installation guide for PAL-AT
alarm/locator panels, sensor cable, cable connectors, and probes. Users (installers) should
independently evaluate the suitability of this information and PermAlert's products for their application
and specific installation. If you receive a PermAlert product that is not described in this manual, contact
PermAlert for the appropriate instructions. Refer to the website, permalert.com (permapipe.com), for the
latest revision of manuals and product data sheets.
1.2 Applications
The PAL-AT system consists of an electronic microprocessor-based alarm/locator panel that monitors
sensor cables and/or probes. The sensor cable may be installed in many applications including:
secondary contained piping, directly in the ground adjacent to pipes or tanks; computer room subfloors;
cleanroom subfloors, or any area where liquids need to be detected. There are several PAL-AT models
available including:
AT20C: Monitors 1 cable up to 2,000 feet.
AT50C: Monitors 1 cable up to 5,000 feet.
AT20K: Monitors up to 2 cables each up to 7,500 feet.
AT40K: Monitors up to 8 cables each up to 5,000 feet.
AT80K: Monitors up to 8 cables each up to 7,500 feet.
1.3 Receiving and Handling Precautions
The following general precautions should be observed:
1. Read this manual carefully before beginning any work. Do not use substitute materials or
short cut recommended procedures. Understanding and following this guide is essential to
avoid installation problems.
2. Collect the needed quantities of all materials well in advance of scheduled work.
3. Check the packing list against received items. Report immediately any shortages or
damaged materials to PermAlert's delivering carrier.
4. All cable must be tested immediately upon receipt following the cable test procedures contained
in this manual. Report immediately to PermAlert any cables that fail this quality control test.
Failure to report within ten workdays of receipt of goods shall waive the purchaser's right to file a
warranty claim.
5. Care must be taken to store all PAL-AT components in a dry and protected area at all times.
Electronic alarm/locator units and sensor cable should be wrapped and sealed with plastic.
6. System drawings, provided by the designer, should indicate the extent, general location, and
arrangement of leak detection equipment, cable, and probes. The contractor (installer) should
become familiar with all details of the installation before proceeding.
7. Electrical work should be performed by a qualified electrician.
1.4 Materials and Equipment Normally Supplied by PermAlert
Each system may include the following items as quoted:
1. Leak detection/location alarm panel
2. Leak sensor cable
3. Jumper cable
4. Cable connector assemblies
5. Adhesive backed cable mounts (CMA) furnished for attachment of sensor cable to flat surfaces

8. Watertight cord grips
9. Shrink tubing for cable connectors
10. RTV adhesive/sealant for cable connectors
1.5 Materials and Equipment Normally Supplied by Installing Contractor
Each system may require the installing contractor to supply the following items:
1. Pull rope, 1/8" diameter, 7 strands, steel wire rope aircraft cable. For installation of cable in
DOUBLE QUIK®, fiberglass, or other plastic piping systems use plastic coated (non-vinyl) wire rope.
Provide pull rope in quantities equal to 120% of system length. (Included with PermAlert piping
systems)
2. Cable spool rack or stand
3. PVC electrical tape
4. Miscellaneous pipe nipples, unions, and fittings, as required to provide watertight jumper cable
connections to sensor cable.
5. 1" rigid or liquid-tight flexible electrical conduit, as required, for installation of jumper cable within
manholes, pits, and buildings. Use 1" conduit hub, OZ Gedney CH-100, connection to junction
boxes.
6. Electrical conduit, junction boxes, and wiring, as required.
7. Ohmmeter for testing jumper cables and sensor cables.
8. 500 volt megger for testing ATP cable only.
9. Hole saw
10. Construction adhesive mastic for attachment of cable mounts to unsealed concrete surfaces
11. Hot air gun for shrink tube application on cable connector assemblies

2 PAL-AT Alarm/Locator Panel
2.1 Alarm/Locator Panel Installation
1. The standard PAL-AT alarm panel must be permanently mounted indoors in a dry area. If the alarm
panel is located outside, it must be installed in a NEMA 3R or 4X enclosure. If PAL-AT is installed
inside another enclosure, a fan is usually required inside the enclosure. The enclosure must not be
located in direct sunlight to prevent excessive heat buildup. In all installations the ambient
temperature must not be less than 0°F and not exceed 120°F
2. A hole is provided for the power conduit entrance (½" conduit) into the alarm unit's enclosure. Use a
knockout punch if larger conduit is required. Inspect and clean the interior of the enclosure before
continuing. Connect all electrical conduits.
3. Wire the unit to an isolated (circuit breaker protected) 120/240 VAC 50/60 Hz circuit. Refer to
Figures 1, 2 or 3 for PAL-AT alarm units wiring diagrams.
4. The PAL-AT alarm unit is connected to the sensor cable using jumper cable (Type JMP-U, JMP-UD,
JPL, or JPP). At least 50' of jumper cable (65' if JPP) must be strung or coiled between the
alarm unit and the connection to the sensor cable. It is recommended to run jumper cable in a
separate conduit for protection of the cable.
5. Remove the partition (cover) over the BNC connector on the PAL-AT panel by removing the 3
mounting screws.
6. Install a standard connector on the jumper cable using the instructions in this manual. A BNC/UHF
adapter is supplied to connect the jumper cable to the BNC connector located under the metal
partition in the PAL-AT panel. The cable must exit the enclosure through the ½" conduit opening
provided. (Use a knockout punch if a larger conduit is required.) Cut the jumper cable to the
required length (minimum 50'), and install a standard coaxial connector as described above.
Replace the partition over the jumper cable connector (see Figures 1, 2 or 3).
