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.
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).
