sounder spacing, placement and special applications please refer to BS 5839 Pt1 : 2002 + A2 : 2008.

Device Installation

The base moulding should be positioned so that access to the locking feature is concealed from general view to
lessen the possibility of unauthorised removal of the device.
Drill the cable entry region(s) in the base moulding as required.
Drill out the desired mounting holes through hole / slot guides as required. Affix the base moulding to a flat surface
using a minimum of 2 screws.
All wiring must be installed in compliance with the recommendations laid out by BS 5839 as well as any special
recommendations documented in the control panel installation manual. The cabling used should be of a 2-core

1.5mm screened, fire resistant type, with the following characteristics:
Max Capacitance Core to Screen ................................................... 180pF / m
Max Capacitance Core to Core....................................................... 100pF / m
