FlexPI™ Quick Start Installation Guide
Introduction
This document provides an overview of FlexPI
™ installation,
setup, and calibration. It is intended as a guideline for
experienced installation technicians. Refer to the FlexPI
Product Guide and the UCM help files for complete details on
installing, setting up, and calibrating FlexPI.
Installing a FlexPI sensor is a four step process:
1. Design the system, and obtain the components.
2. Install the processor, enclosure, and power supply.
3. Install the sensor cable, terminator, and alarm data cables.
4. Setup, calibrate and test the system.
The typical FlexPI system includes a processor in a plastic
enclosure, sensor cable and a terminator. Customer-supplied
cable fasteners, alarm data wiring, alarm annunciator, and a
power supply are also required.
Optional components include non-sensitive lead-in cable,
splice kits, and Windows-based Universal Configuration
Module (UCM) software.
Cable spacing and fastening
recommendations
FlexPI sensor cable spacing depends on the type of building
material, and the required level of security. Using multiple
cable passes with reduced cable spacing provides the best
detection sensitivity, and the highest level of security. Materials
that conduct vibrations well require fewer cable passes than do
surfaces that have a dampening effect on vibrations.
For security cages and fencing:
cable spacing up to 1 m (3.3 ft.) fastened every 30 cm (1 ft.)
For walls:
cable spacing up to 1.25 m (4 ft.) fastened every 30 cm (1 ft.)
For roofs with steel beams:
cable spacing up to 1.8 m (6 ft.) fastened every 30 cm (1 ft.)
For roofs with wooden trusses:
cable spacing app. 60 cm (2 ft.) fastened every 30 cm (1 ft.)
The minimum recommended cable spacing is 30 cm (1 ft.).
Installation rules
Mount the enclosure indoors at the start point of the sensor
zone. OR mount the enclosure up to 30 m away from the zone
and use lead-in cable to make the connection to the processor.
Use one processor and sensor cable to protect one type of
surface.
Keep walls, roofs, ceilings and floors separate.
DO NOT allow the sensor cable to fall off the reel during
installation.
DO NOT bend, twist, stretch, jerk, knot, or kink the sensor
cable.
DO NOT place objects on the sensor cable.
Sensor cable MUST NOT be nicked, or scraped.
Secure the cable to the surface at a constant height above
ground.
The sensor cable must be in close contact with the protected
surface.
Install fasteners so they hold the cable firmly against the
surface without pressing into, or distorting the cable jacket.
Avoid tight turns in the sensor cable. The smallest allowable
bend radius for MEX sensor cable is 4 cm (1.5 in.).
Apply consistent light tension (2 kg, 4.5 lb) to the cable while
attaching it to the surface, to prevent the cable from sagging
between fasteners.
For installation in areas where the cable may be subject to
damage from equipment or vandalism, install the cable inside
metal conduit.
Use cable loops for increased sensitivity near support
structures and around corners.
For security cages and fences:
Attach the sensor cable to the secure side of the cage/fence
(the side opposite the threat).
Attach the sensor cable at least 30 cm (1 ft.) away from
horizontal support bars and other cables.
Hand tighten the cable ties until the cable is snug against the
cage.
DO NOT use mechanical tighteners, or over-tighten the cable
ties.
DO NOT allow the sensor cable to be pinched between the
cage and a support post, or any other object.
