6.2 Installation Instructions
The flexibility of the Precept EN Output Expansion
System allows many different combinations of
enclosure/PSU/output modules. As such these
instructions cannot cover every single variation and
so provide general instructions only.
1. Carefully remove the panel from the packing and
lay the panel on a flat surface.
2. Open the door of the panel.
3. Locate the spares bag[s] and check contents,
which should comply with Table 1

Matching 25mm knock-outs are provided on the
right hand face of the Precept EN 8/16 fire alarm
panel enclosure and the left hand face of the
Precept EN 4 Exp output expansion enclosure to

is provided for connecting Precept EN 32 control

knock-outs in the adjoining faces of both fire panel

box, aligning the two enclosures via the coupler
then mark. Fix the expansion enclosure to the wall
