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 not described in this manual, contact PermAlert for the
appropriate instructions. PermAlert is a division of Perma-Pipe, Inc. Refer to the PermAlert website,
permalert.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 fuel 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:
AT30C: Monitors 1 cable up to 3,000 ft [900 m].
AT75C: Monitors 1 cable up to 7,500 ft [2300 m].
AT30K: Monitors 4 cables each up to 7,500 ft [2300 m].
Applications monitoring cables in hazardous locations must use a Zener Barrier Panel (see section 3).
1.3 Receiving and Handling Precautions
The following general precautions should be observed:
1. 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 the 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 the tests. Failure to report
within ten workdays of receipt of goods shall waive the purchaser's right to file a warranty claim.
5. The recommended minimum bend radius for all sensor and jumper cables is 1.5” [38mm].
6. Care must be taken to store all PAL-AT components in a dry and protected area at all times.
Electronic alarm/locator panels and sensor cable should be wrapped and sealed with plastic.
7. 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.
8. Electrical work should be performed by a qualified electrician.
