C
collective effect A phenomenon common only to air sampling
smoke detection systems. The sensitivity of the
individual detection points (smoke sampling
points), in contrast to point-type detectors, does
not remain constant. The sensitivity of the
individual air sampling points depends on the →
response sensitivity and the number of air
sampling points.
collective fault
A non-differentiated, i.e. non-localisable → fault
signal which reports to a superior system.
contact load Contact load describes the maximum load at
which a relay contact can be switched.
D
detection line
Monitored transmission line ( → primary line) to
which the smoke detectors are connected with the
→ central fire panel.
detection reliability This is the measure of reliability with which
phenomena are detected and reported and for
which a detection system is used.
detector group
Collection of smoke detectors in a → detection line
for which a separate display is installed in the
→ central fire panel.
detector module
modular
→
scattered light smoke detector
optimised for use in air sampling smoke detection
systems and equipped with a special air feed, a
Flow-Init button for initialisation of the integrated
→ air flow sensor, a diagnostic LED with flash code
for indicating faults and a → DIL-switch
detector module sensitivity
also: sensitivity
The detector module sensitivity is adjustable
between the levels 1 to 4 and is the generic term
for → response sensitivity.
DIL switch D
ual
I
n
L
ine; e.g. to set the response sensitivity, the
air flow sensor, the delay period for → alarm and fault,
to set the fault display to latched or non-latched and
to activate or deactivate → LOGIC · SENS .
drift Method of compensating detector soiling which
could change the quiescent signal by moving the
zero point.
E
electromagnetic compatibility (EMC) This is the ability of an electrical or electronic
system to operate correctly in its electromagnetic
environment and have no adverse affect on this
environment.
End-of-line resistor
Element at the end of a → detection or control line
to check the line for broken wires and short
circuits.
