4.4 pounds (2.0 kilograms)
C7052J Detector
Aluminum: 6.0 pounds (2.7 kilograms).
Stainless Steel: 14.0 pounds (6.4 kilograms).
OPTIONS
Power supplies are available for operating the R7495D
and C7052J from line (mains) voltage.
The Q4004 Mounting Cage is designed for holding up
to eight micro-module devices and is recommended for
ease of installation and servicing. Mounting cages that
hold fewer modules are also available. See Figure 18.
Optional filler panels (part number 002188-001) can be
used to cover unused sections of the mounting cage.
Locking devices must be used on detector housings to
comply with applicable regulations in some areas
(BASEEFA/CENELEC).
Q1113 Air Shields for areas where there is an abnormal-
ly high level of airborne contaminants. Two Q1113 Air
Shields are required for each detector.
Q9001G Swivel Assembly (part number 004404-001) for
easy mounting and sighting of detector assemblies.
T2P/Q1201 Laser with holder for sighting and identifying
the detector cone of vision.
RESPONSE CHARACTERISTICS
The response time of the detector is a function of fuel,
fire size, distance, orientation of the fire source and the
field programmable controller settings. As with all fire
tests, results must be interpreted according to the indi-
