Elimination of False
Alarms
The combination of multiple sensors and wavelength range settings makes the IPES ‐ IR/UV an
excellent choice for elimination of false positive indicators caused by non ‐ flame sources of
radiation such as artificial lighting, direct and indirect sunlight, lightning, arc welding and
metal grinding.
See additional important considerations for eliminating false alarms in section 3.0 Safety.
An Alarm condition will normally override a Fault condition unless a loss of operating power
impairs the detector’s ability to generate or maintain an alarm. The IPES ‐ IR/UV reports both
Fault and Alarm conditions exclusive of each other. This means both a Fire and Fault can be
reported at the same time if they occur simultaneously.
Serviceability The IPES ‐ IR/UV remains serviceable in non ‐ heated rooms or under sheds at temperatures
from –40°F to +185°F (–40° to +85°C).
LED Normal, Fire and Fault conditions are indicated by two red LEDs located on the cover. Refer to
Table 4 ‐ 1: Determining LED Conditions, below.
Optical Integrity To maintain reliability of the IPES, the optical devices are automatically self ‐ tested for
radiation transmission every 25 to 45 minutes. This routine test does not require the use of a
test lamp. This test determines whether any dust or other contamination has formed on the
detecting windows which would scatter the infrared radiation.
