Overview of Detector Bases

Detectors in the FAP-420/FAH-420 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-420/FAH-420 Detector Head. Cable diameters of up to 2.5 mm
used.
The detector head can be secured against unauthorized removal with a variable lock.
MS 400
Der 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 and MS 400 B 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.
