The SENTRI4 panel
(SENTRI4) is an
analogue addressable
fire alarm panel
designed to the
requirements of
EN54-2 : 1997
and
EN54-4 : 1997
The panel can
accommodate up to 4 loop circuits for the
connection of Sentri range of analogue
and addressable devices. The panel has
an integral mains derived power supply
and integral batteries. The batteries
supply standby power in the event of
mains power failure. A lockable front door
prevents unauthorised access to fire
alarm controls but allows all of the
indicators to be seen. The panel has
integral zonal indicators to provide zone
fire or fault indications. Two push button
controls are located on the front door
below the display that enable Fire
messages to be scrolled in the event of
multiple fires. The panel is designed for
surface or semi-flush mounting with rear
and top cable entry points.
