Table 2 below contains a list of procedural guidelines for installation of the
detector.
Table 2: Procedural guidelines
Do
Don’t
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.
P
lace 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 prot
ected 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.
Close unused pipe inlet ports on the detector to
ensure opt
imal operation.
Set the appropriate ClassiFire alarm factor for
the area to be detected.
Set the detector
address switches correctly
when used in a network.
Ensure
that the detector is properly grounded.
Drop the detector.
Install detectors in damp or exposed areas.
Remove or connect boards when the detector is
powered up.
Connect internal 0 volt terminals to local earth.
Attempt to reuse dust separator (filter)
cartridges once removed.
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.
Place the detector near high power RF sources.
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.
Use sampling pipe of less than 27 mm (1 inch)
outside diameter without a suitable 27 mm (1
inch) pipe adapter. It is important that there are
no leaks where the pipe connects to the
detector.
Use excessive force when fitting sampling pipes
as this may damage the detector.
Installation
Mechanical installation
The docking station is connected to the installed sampling pipework and fixed to
the mounting surface using three screws of a type appropriate to the mounting
surface. Ensure that the sampling and exhaust pipes are securely seated in the
pipe ports before securing. If using a piped exhaust docking station, be sure that
the sampling and exhaust pipes are fitted into the relevant ports as shown in
Figure 4 on page 10.
Removing the front cover
To remove the front cover, unfasten the six attachment screws on the front of the
unit. The cover may then be removed.
