SAFETY SUMMARY
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 High Sensitivity Smoke Detection system.
Disconnect all sources of power before servicing. The High Sensitivity Smoke Detector (HSSD)
system and
associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while
the unit is energised. Do not attempt to install, service, or operate this unit until this manual is read and understood.
-
Application of the system:
To reduce the possibility of inadvertent alarms caused by “normal” ambient conditions,
the HSSD system must be monitored before final commissioning. Special attention should be given to systems
installed where elevated levels of background ambient smoke or particulate concentrations are present within the
protected area. Examples of such applications would be: kitchens, boiler rooms, manufacturing or other processes
where open flames or unprotected heating surfaces are present.
This monitoring must be conducted for a minimum of two weeks and be conducted during all normal
situations which may cause an elevated level of smoke or particulate to occur in the protected area. This
monitoring process will determine the most appropriate detector sensitivity, alarm threshold and delay
settings for the application.
-
Use with fire suppression systems:
Under no circumstances should the detector be used to directly initiate
the release of a fire suppression system
. When used as detection for a fire suppression system, the detector
should provide one initiation signal of a cross zoned detection system.
-
Static Electricity:
Electronic components and modules can be damaged by small amounts of static electricity.
When handling these components or modules, wear an antistatic wrist strap or grounding device.
GENERAL SAFETY NOTICES
The following must be observed to maintain personnel safety.
The following general safety notices supplement specific warnings and cautions appearing in the manual. The safety
precautions in this section must be understood and applied during operation and maintenance.
TEST EQUIPMENT
Make certain test equipment is in good operating condition. Do not touch live equipment or personnel working on live
equipment while holding a test meter. Some types of measuring devices should not be grounded; these devices
should not be held when taking measurements.
FIRST AID
Any injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention
immediately.
GENERAL PRECAUTIONS
The following general safety precautions are to be observed at all times:
1. All electrical components associated with equipment shall be installed and grounded in accordance with local
regulation requirements.
2. Special precautionary measures are essential to prevent applying power to equipment at any time maintenance
work is in progress.
3. Before working on electrical equipment, use a voltmeter to ensure that system is not energised.
4. When working near electricity, do not use metal rules, flashlights, metallic pencils, or any other objects having
exposed conductive material.
5. When connecting a meter to terminals for measurement, use range higher than expected voltage.
