Trutest 800 Kit
APPLIES TO BOTH CONVENTIONAL AND INTELLIGENT SYSTEMS.
CONVENTIONAL DETECTORS
These detectors have no means of measuring their own sensitivity. Their sensitivity drifts, and so it should be tracked over a period of time, using Trutest.
ANALOG/INTELLIGENT DETECTORS
Interrogating the fire system panel of an intelligent system enables, at best, a check of the value of ‘clean air' response levels. It does not verify the condition of the vents or ability of the detector to receive smoke into its sensing chamber. Correlating an unmeasured smoke source (e.g. hand-held can of smoke) with a panel interrogation also does not produce a quantified test, as US NFPA 72 confirms: "... The detector sensitivity shall not be measured using any device that administers an unmeasured concentration of smoke or other aerosol into the detector". NFPA 722007 (10.4.4.2.6)
By introducing a measured and controlled smoke stimulus into the sensing chamber, Trutest enables cross-references to be made between the independent Trutest readings and the analog readings from the system panel. Only in this way can a true test of intelligent systems be achieved.
Some standards permit sensitivity test frequencies to be extended after proven detector stability. This relies on tracking drift, which can be done only by measuring actual sensitivity readings. Trutest does not need two tests to check the upper and lower limits (which, in itself, does not establish actual sensitivity). Just one test provides an actual reading in % I ft which can be compared year on year to establish drift.
