ImPORTaNT SafETy NOTES

WarnIng

Do not open the detector assembly in a hazardous
area when power is applied. The detector contains
limited serviceable components and should never
be opened. Doing so could disturb critical optical
alignment and calibration parameters, possibly
causing serious damage. This type of damage
could be undetected and could result in failure to
see a fire and/or false alarm.

CaUtIon

The wiring procedures in this manual are intended
to ensure proper functioning of the device under
normal conditions. However, because of the
many variations in wiring codes and regulations,
total compliance to these ordinances cannot be
guaranteed. Be certain that all wiring complies
with the NEC as well as all local ordinances. If
in doubt, consult the authority having jurisdiction
before wiring the system. Installation must be
done by a properly trained person.

CaUtIon

To prevent unwanted actuation or alarm,
extinguishing devices must be disabled prior to
performing system tests or maintenance.

CaUtIon

The UV flame detectors are to be installed in places
where the risk of mechanical damages is low.

attEntIon

Remove the protective cap from the front of the
detector before activating the system.

attEntIon

Observe precautions for handling electrostatic
sensitive devices.

The following is a partial list of compounds that exhibit
significant UV absorption characteristics. These are
also usually hazardous vapors. While generally of little
consequence in small amounts, these gases can restrict
UV detection if they are in the atmosphere in heavy
concentrations. It should also be determined whether or
not large amounts of these gases may be released as a
result of a fire-causing occurrence.

Acetaldehyde

Methyl Methacrylate

Acetone Alpha-Methylstyrene
Acrylonitrile Naphthalene
Ethyl Acrylate

Nitroethane

Methyl Acrylate

Nitrobenzene

Ethanol Nitromethane
Ammonia 1-Nitropropane
Aniline 2-Nitropropane
Benzene 2-Pentanone
1,3 Butadiene

Phenol

2—Butanone Pyridine
Butylamine

Hydrogen Sulfide

Chlorobenzene Styrene
1-Chloro-1-Nitropropane Tetrachloroethylene
Chloroprene Toluene
Cumene Trichloroethylene
Cyclopentadiene

Vinyl Toluene

O-Dichlorobenzene Xylene
P-Dichlorobenzene

If UV-absorbing gases may be a factor in a given
application, precautionary measures should be taken.
Detectors can be placed closer to the potential hazard
area, and/or the sensitivity of the detection system can be
increased. Contact the factory for further details.

Substances such as methane, propane, butane, hexane,
camphor and octane are not UV absorbing.
