FAA-MSR 420
The FAA-MSR 420 is a detector base with a change-over contact
relay (type C).
The FAA-MSR 420 Detector Base with Relay can only be used in
connection with the Local Security Network improved version
(FPA-5000 Modular Fire Panel).
MSC 420
The MSC 420 Additional Base was designed specially for
surface-mounted cable feed via cable protection conduits and
has two opposing pre-cut entry points of 20 mm diameter and
two additional opposing and prepared entry points for
diameters up to 28 mm.
The additional base has a diameter of 120 mm and a height of
36.7 mm. To protect against condensed water penetration, a
seal is placed on the bottom of the MSC 420.

Installing the Base

The detector bases are screwed to the even, dry surface using two screws approx. 55 mm
apart.
To feed cables through for surface mounting, punch out the prepared entry points (X) on the
housing.
For flush-mounted cable insertion, feed the cable through the opening in the middle of the
base.
The long holes marked in the sketch with "Y" are intended for base installation in a flush
mount back box and should only be used for this purpose.
NOTICE!
Cables can be fed in and out on the same side.
On the MSF 400 and MSC 420, punch out the integrated seal with a sharp tool. Do not cut
with a knife.
