Installation guidelines
The following is a brief set of guidelines on installing detectors:
• The detector should normally be mounted at a level where there is easy
access.
• The exhaust air from the unit must not be impeded in any way. If the detector
is mounted in a different air pressure from where the air is being sampled (for
example an air duct), then a pipe must be routed from the exhaust port back
to the same air pressure zone as the sampling holes.
• All wiring must comply with NEC, NFPA 70, CSA C22.1, local codes and
standards, and the requirements of the local AHJ. All signal cables must be
suitable for the application.
• The detector must not be placed in areas where either the temperature or
humidity is outside the specified operating range.
• The detector 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).
Table 3 on page 17 contains a list of procedural guidelines for installation of the
Nano detector.
