Chapter 1: Introduction

Tri-metallic cores

Protective coating

Advanced temperature-sensitive polymer

Overview

Alarmline II Digital Sensor Cables are a flexible durable and cost-effective form of
fire detection, suitable for protecting a wide range of commercial and industrial
applications.

They provide flexibility in installation enabling them to be used for general area
protection or proximity detection close to a specific point of risk. A wide range of
alarm temperatures, protective coatings, and installation fixings ensure system
design and installation is specific to the risk. Alarmline II Digital Sensor Cables
are especially suited for use in confined areas or areas with harsh environmental
conditions where the use of other forms of detection is limited.

Alarmline II Digital Sensor Cables can be easily integrated to any fire control
panel through a moni to r ed inp ut (a conventional detection zone, zone monitor
unit, or switch monitor unit, etc.). The Digital Location Control Unit provides
additional functionality to the Alarmline II Digital Sensor Cable system by being
able to determine the alarm location along extended lengths of digital sensor
cable (up to 3000 m).

This manual provides technical information, installation guidelines, and design
recommendations for a selection of typical applications (it does not cover all
possible applications – contact Kidde Prod uc t s Ltd. technical support for further
design and installation advice).

Operation

Alarmline II Digital Sensor Cables are constructed from a twisted pair of tri­metallic conductors covered with an advanced temperature-sensitive polymer. A
protective outer coating is then extruded over the twisted pair.

The two inner cores of the sensor cable are tightly twisted together to provide a
mechanical tension bet ween them. When the temperature-sensi ti ve polymer
reaches a specified temperature it begins to soften, the tension between the two
inner cores forces the two conductors together creating a short circuit.

The simplistic operation of the Alarmline II Digital Sensor Cable makes it
compatible with any control equipment capable of accepting contact closure type
initiating devices.

Product range

The Alarmline II Digital S ensor Cable range consists of five fixed-temperature
alarm cables, each with a range of protective coatings.
