"High flow" error messages
Check that the pipe is pushed home into the inlet and is not broken or cracked
Check that installed pipework is fitted with an endcap. PipeCalculator pipe modelling software prompts the use
of appropriate end caps. Open bore pipes are not recommended.
Check that the high flow fault threshold is not set too low (see Section 4.29)

Do’s and Don’ts
DO
Ensure that the
ClassiFire
alarm factor is appropriately set.
Ensure that 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 sampling 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 (temperature -10 to +60°C, (humidity 0- 95%, non-condensing).
DON’T
Forget to set the appropriate
ClassiFire
alarm factor for the area to be detected.
Forget to set the Detector Address Switches correctly when used in a network.
Site 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 re-use dust separator cartridges once removed.
Attempt to adjust or alter detector settings other than via the user-programmable functions. In particular, the
setting up of the laser is a precision task, and once set up the potentiometers should be left alone. If it is
suspected that the laser alignment has shifted (e.g. after dropping the detector), it should be returned to
Ampac for recalibration.
Place the detector near high power RF sources.
Operate the detector with the front cover removed, or with one or more of the cover fixing screws loose or
missing.
Test the response of the detector using aerosol synthetic smoke.
