2. General Description
The FIRECLASS DUO-CEL Panel range is fully
compliant with the mandatory requirements and
selected optional requirements of EN54 parts 2 and
4.
The FIRECLASS DUO-CEL equipment range
consists of the following:
 Standard Panels:
1, 2, 4 and 8 zone versions.
 Twin-Wire Panels:
1, 2, 4 and 8 zone versions.
 Repeater:
8 zone 24Vdc & 230Vac versions.
Each panel in the range is housed in an
Acrylonitrile Butadiene Styrene (ABS) Plastic
enclosure with a combined display & control board
mounted to the back box. An ABS cover is fixed
over the display/control board, leaving the field
terminals, configuration switches, links and user
controls easily accessible.
The front cover of the enclosure clips onto the back
box and is fixed by one screw on the top and two
screws on the bottom.
The PCB cover is fitted with a polyester overlay
providing user controls and indications. All display
text is printed on the overlay, with an insert for the
zone location text that slides into a pocket in the
overlay.
User controls are locked & unlocked via a plastic
key which is inserted through a keyhole in the cover
and cannot be removed when in the ON position.
All indications are implemented using LEDs, three
of which are not visible when the enclosure front is
fitted.
The power supply and standby batteries are
housed within the panel enclosure. The power
supply is fitted underneath the PCB with the mains
supply cable terminals accessible for easy
installation. The batteries are fitted in the back box
and retained by a plastic bar which is fixed to the
back box by a single screw.
Field cable Earth shields can be terminated to a
functional earth bar located in the rear of the panel
enclosure.
