Explanation of the abbreviations and pictograms
Wn = nominal width
Hn = nominal height
Dn = nominal diameter
E = integrity
I = thermal insulation
S = smoke leakage
Pa = pascal
ve = vertical wall penetration
ho = horizontal floor penetration
o -> i = meets the criteria from the outside
(o) to the inside (i)
i <-> o = fire side not important
V AC = Volt alternating current
V DC = Volt direct current
E.TELE = power supply magnet
E.ALIM = power supply motor
V = volt
W = watt
Auto = automatic
Tele = remote controlled
Pnom = nominal capacity
Pmax = maximum capacity
GKB (type A) / GKF (type F): "GKB"
stands for standard plasterboards (type
A according to EN 520) while "GKF"
plasterboards offer a higher fire resistance
for a similar plate thickness (type F
according to EN 520)
Cal-Sil = calcium silicate
OP = option (delivered with the product)
KIT = kit (delivered separately for repair or
upgrade)
PG = connection flange to the duct
Sn = free air passage
ζ [-] = pressure loss coefficient
Q = air flow
∆P = static pressure drop
v = air speed in the duct
Lwa = A-weighted sound power level
Lw oct = sound power level per octave
midband
dB(A) = A-weighted decibel value
∆L = correction factor
240
fire resistance 240 minutes
suitable for built-in installation
intermediate dimensions on request
