The 802SB and 901SB MX Addressable Loop
sounder bases provide a sounder function for
MX addressable systems. They produce a user-
selectable tone under control from the Control and
Indicating Equipment (CIE.) via the MX detector or
sounder driver (SAB801 or SAM800) plugged into
the sounder base. The volume can be adjusted
on-site using a special tool. The tones are DIP
switch selectable, including the ISO 8201 tone.
The 802SB is loop-powered and up to 250 are
supported on the MX loop at low volume (refer CIE.
details2). It is identified by a white park clip.
The 901SB is externally powered by a 24Vdc power
source and up to 250 are supported on the MX
loop. It is identified by a blue park clip.
Mounting
The sounder base should be positioned as per the
site plan, fixed to a suitable flat surface strong
enough to support the weight of the base and
detector. Two screws 4mm diameter are required
(not supplied) for fixing the mounting flange.
Feed the wiring through the mounting flange cable
entry hole and secure the flange to the surface.
Feed the wiring through the cable entry hole in
the sounder base and fit the base to the flange.
Connect the wiring as per the diagram on page 2.
Do not block the gap between the flange and the
sounder base.

Features
// Compatible with MX Addressable Loop
on SIMPLEX 4100ESi, VIGILANT MX1 and
VIGILANT MX4428 panels
// MX Loop powered 802SB
// External 24V powered 901SB

series detectors
Removal of the detector or loss of power to the loop
will cause the sounder to cease sounding. The sounder
must be fixed to a flat ceiling or a suitable electrical
backbox with 50mm fixing centres.
