Screws for fastening base
1.
Pull the cable through one of the cable bushings
(3)
. A cable tie around the cable sheath
will secure the cable against being pulled out accidentally.
2.
Insert the ceiling mount back box in the false ceiling from below.
3.
A triangular marking (Pos.
M
) is impressed into the outer edge of the ceiling mount back
box. Turn the ceiling mount back boxes so that all markings are in a line. In this way, the
long, middle windows of the detectors will later appear in a line to give a harmonious
overall visual effect.
4.
Tighten the brackets

Notice!
It is recommended that for the usual, soft false ceiling panels, you do not use a cordless
screwdriver.

The base housings (refer to figure) are made of white polycarbonate.
The screw terminals (for cables with cross section from 0.3
mm

to 3.3
mm

) guarantee a
secure electrical connection through the clamped contacts when mounting the detector. The
bases are provided with three mounts for cable ties. These can be used for fastening the base
during the wiring-up.
End-of-line resistor
As the last base on the stub line you always have to place an FCA‑500‑E‑EU detector base.
Inside the base, a suitable EOL resistor has to be mounted between the two screw clamps
(refer to figure, position EOL).
