ENVIRONMENTAL CHARACTERISTICS
TEMPERATURE RANGE—
Operating: 0°C to +49°C (+32°F to +120°F ).
Storage:
0°C to +70°C (+32°F to +158°F).
RELATIVE HUMIDITY—
0 to 93% relative humidity.
NOTE
Water or other liquids on the face of the detector
may decrease sensitivity.
ENCLOSURE RATING—
IP67.
VIBRATION—
Compliance with FM Approval Standard FM 3260: 2000.
ELECTROMAGNETIC INTERFERENCE—
Highly resistant to radiated and conducted Electromagnetic
Interference (EMI). The detectors are immune to radiated
fields of 100 volts per meter, including amplitude 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.
CERTIFICATION—
FM:
Refer to Appendix A for details.
CE:
See Special Conditions for Safe Use.
Special Conditions for Safe Use:
• The PM-5MPX Detector may only be installed,
connected or removed when the area is known to be
non-hazardous.
• The PM-5MPX Detector may only be used in indoor
applications that are independent of building fire
protection systems.
• The PM-5MPX plastic cover is liable to be damaged by
impact. The unit should be installed in such a manner
as to protect the cover from mechanical damage.
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 (refer to Appendix A for test
result data), and within the 110° field of view (see Figure
2). The PM-5MPX detector can respond to fires in as little
as 25 milliseconds. Actual detection time depends on the
distance between the detector and the fire, the source of
fuel, ignition sources and other aspects of the initial fire
stages. The detector has a typical response time of <0.5
second to the fires specified in Appendix A. The detector
can respond most quickly to closer or larger fires, but is
unlikely to detect fires occurring further than the indicated
distance. The range is reduced when the fire occurs
close to the edge of the field of view of the detector. At
the edge (±55° off axis) the range is reduced no more
than 50%.
NOTE
The detector range to fires not listed in Appendix A
will vary and should be verified by fire tests using
the fuel in question. Please contact Detector
Electronics Corporation for further information.
