Introduction
The self-contained MXCE panels provide all the
required monitoring and control functions to
install a complete fire detection, alarm and
extinguishing system. The MXCE T540 and T550
controllers support 2 and 4 detection zones
respectively. Coincidence operation is available
as standard on zones 1 and 2. Additionally on
the T550, zones 3 and 4 can be used for
extinguishing (coincidence) or as independent fire
alarm zones.
The exceptionally priced T540 and T550
controllers are designed as feature enhanced,
aesthetically modern replacement for the current,
more expensive and heavily dated T530 and T520
Extinguishing panels. Additionally, the
introduction of 2-wire sounder capability
(detectors and sounders on the same 2-wire
circuit) to the extinguishing systems market will
achieve significant cost and installation savings.
Installation Features
The MXCE offers flexible mounting arrangements,
with easily removable door, multiple conduit
entries and large terminations, designed
specifically for simplified installation.
• Reversible back-box for top or bottom conduit
and cable entry
• Surface or semi-flush mount
