Table 2 below contains a list of procedural guidelines for installation of the ReadySET
detector.
Table 2: Procedural guidelines
Do Don’t
• Ensure that the ClassiFire alarm factor is
appropriately set.
• Ensure that the power and signal cables are
correctly connected before powering up by
use of cable identifiers or electrical
continuity checks. Incorrect connection could
damage the detector.
• Ensure that cable of an appropriate
approved type is used for interconnection.
• Place sampling points so that the detector
will be able to detect smoke at the earliest
opportunity.
• Ensure that the detector exhaust is in an
area with the same atmospheric pressure
as the sample pipes, either by placing the
detector physically in the protected area or by
leading a pipe from the detector exhaust to the
protected area.
• Ensure that the environment of the protected
area is within the environmental operating
parameters of the detector (32º to 100º F or
0º to 38º C, humidity 0 - 90%, non-
condensing).
• Ensure the detector is properly grounded.
• Remove or connect boards when
the detector is powered up.
• Attempt to adjust or alter detector
settings other than via the user-
programmable functions. Any
attempts to adjust the laser
potentiometer are detectable and will
void the warranty on the product.
• Drop the detector or use excessive
force when fitting sampling pipes as
this may damage the detector.
• Connect internal 0 volt terminals to
local earth.
• Use sampling pipe of less than 1
inch (27 mm) outside diameter
without a suitable 1-inch (27- mm)
pipe adapter. It is important that there
are no leaks where the pipe connects
to the detector.
• Place the detector so close to other
equipment that there is insufficient
room to access and change the dust
separator (filter) or access the RS-
232 connector (if installed).
• Install the detector near high power
RF sources or in damp or exposed
areas.
• Attempt to re-use dust separator
(filter) cartridges once removed.
Removing the front cover
To remove the front cover, unfasten the cover securing screw located on the bottom of
the unit. The cover may then be removed.
