Stratos EX Hazardous Area Aspirating Smoke Detection System Installation Manual 3
General precautions
The following general safety precautions are to be observed at all times:
• All electrical components associated with equipment should be installed and
grounded in accordance with NEC and local regulatory requirements.
• Special precautionary measures are essential to prevent applying power to
equipment at any time maintenance work is in progress.
• Before working on electrical equipment, use a voltmeter to ensure that the
system is not energized.
• When working near electricity, do not use metal rulers, flashlights, metallic
pencils, or any other objects having exposed conductive material.
• When connecting a meter to terminals for measurement, use a voltage range
higher than the expected voltage to be measured.
Installation precautions
Adherence to the following will aid in problem-free installation with long-term
reliability.
Several different sources of power can be connected to this detector.
WARNING: Disconnect all sources of power before servicing. Control unit and
associated equipment may be damaged by servicing while the unit is energized.
Do not attempt to install, service, or operate this control unit until this manual is
read and understood.
Like all solid-state electronic devices, this system may operate erratically or can
be damaged when subjected to lightning induced transients. Although no system
is completely immune from lightning transients and interference, proper
grounding will reduce susceptibility.
Thise manual gives information likely to be needed for most installations, but for
more detailed information on subjects such as programming, networking, and
pipe networks, please refer to the SenseNET Software User Manual, Remote
Configuration Software Manual, and PipeCAD System Design and Installation
User Manual.
The label located on the laser chamber signifies that the unit is a Class 1 Laser
product as specified in IEC 60825-1. The unit incorporates a Class 3B embedded
laser which must not be removed from the detector as retinal damage may result
if the laser beam enters the eye.
WARNING: The use of overhead or outside aerial wiring is not recommended
due to the increased susceptibility to nearby lightning strikes. Consult with the
Technical Support department if any problems are anticipated or encountered.
