3 Installation
Before installing the detector the local standards for installation of aspirating detection systems must be
consulted as these standards differ throughout the world. Specific advice for one country may not be
applicable to another. The following is a brief set of guidelines on installing detectors:
 The detector will normally be mounted at a level where there is easy access to the unit for
configuration and programming.
 The exhaust air from the unit must not be impeded in any way. If the unit is mounted in a different
air pressure from where the air is being sampled (for example an air duct), then a pipe must be
taken from the exhaust port back to the same air pressure zone as the sampling holes.
 Sampling holes should be free from burrs and swarf.
 All signal cables must be screened and must be of a suitable type. The specific type of cable will
normally depend upon the local fire regulations.
 The unit must not be placed in areas where either the temperature or humidity is outside the
specified operating range.
 The unit should not be placed in close proximity to any equipment expected to generate high Radio
Frequency levels (such as radio alarms) or units generating high levels of electrical energy (such
as large electric motors or generators).
 In order for the installation to conform to EN54-20, pipes must conform at least to EN61386-1 Class

3.1 Docking Station
The basic principle behind installation of the FIRElink-100 is that all wiring and pipe-work is installed using
a docking station. This is a convenient feature which means that the detector can be dismounted or
replaced without disturbing any wiring or installed pipe-work.
