Overview of Detector Bases

Detectors in the FAP-425/FAH-425 series are operated in one of the detector bases listed
below.
The detector bases are suitable for surface and flush mounting, and provide separate fixing
points for ceiling and flush mount back boxes. They also fit all common bore patterns.
The bases are made from white ABS plastic (color similar to RAL 9010) and have a matte
surface finish.
The bases have screw terminals for connection of the detector and its accessories to the fire
panel. Contacts connected with the terminals guarantee a secure electrical connection when
installing the FAP-425/FAH-425 Detector Head. Cable diameters of up to 2.5 mm
The detector head can be secured against unauthorized removal with a variable lock.
MS 400
The MS 400 is the standard detector base. It has seven screw
terminals.
MS 400 B
MS 400 standard detector base with Bosch-branding.
FAA-420-SEAL
For using the FAP/FAH detectors in damp environments you can
supplement the MS 400, MS 400 B and FAA-MSR 420 detector
bases with the FAA-420-SEAL damp room seal. The damp room
seal is made of TPE and prevents condensing water from entering
the detector.
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.
