ENVIRONMENTAL CHARACTERISTICS
TEMPERATURE RANGE—
(Operating and Storage) 32° F to +158° F (0° C to +70°
C).
RELATIVE HUMIDITY—
0 to 100% relative humidity.
NOTE
Water or other liquids on the face of the detector
may decrease sensitivity.
ENCLOSURE RATING—
IP67.
VIBRATION—
Compliance with FMR Approval Standard 3260.
CE—
Conforms to all relevant European norms.
ELECTROMAGNETIC INTERFERENCE—
Highly resistant to radiated and conducted Electromag-
netic Interference (EMI). The detectors are immune to
radiated fields of 100 volts per meter, including ampli-
tude and frequency modulated (AM & FM) signals in the
frequency range of 1 MHz to 1 GHz. The detectors can
operate in the presence of conducted noise levels up to
1.0 VRMS in the frequency range of 30 Hz to 250 kHz
while the input voltage, including noise, remains
between 9 and 30 volts.
DETECTOR PERFORMANCE
DETECTION RANGE AND RESPONSE TIME
Best performance is achieved when the detector is
mounted so that the protected area is within the range,
or detection threshold distance, given in Table 2 for var-
ious flammable hazards, and within the 110° field of view.
See Figure 2. The PM-5MP and PM-5MP+ detectors can
respond to fires in as little as 25 milliseconds. Actual
detection times of fires depends on the source of fuel,
ignition sources and other aspects of the initial fire
stages. The detector has a typical response time of one
second to the fires specified in Table 2. The detector can
respond most quickly to closer or larger fires, but is
unlikely to detect the fires specified in Table 2 when they
are further away than shown. The range is smaller for
sources when they are close to the edge of the field of
view of the detector. At the edge (±55°) the range is
reduced no more than 50%.
NOTE
The detector range to fires not listed in Table 2 will
vary and should be verified by fire tests using the
fuel in question. Please contact Detector
Electronics Corporation for further information.
