Important Safety Information
Connections to the 240V AC mains supply must be carried out by a qualified electrician
or similar competent person, and made in accordance with accepted safety practices.
A two-pole switch (as provided by a Consumer Unit or Switch-Fuse) must be included
to isolate both Live and Neutral during Installation or Maintenance. The circuit must be
protected by a fuse or other current-limiting device, rated according to the capacity of
the cable used, up to a maximum of 10A. Use only mains cable to BS6004 or
equivalent, within the following specified limits:
Min Max
Conductor Diameter 1.0mm (0.8mm

)
Cable Diameter 4.0mm 8.0mm
The power supply is fitted with an internal mains fuse, and a battery fuse; always
replace with the correct type and rating. The fuse must be of the 20mm glass type,
approved to BS EN 60127 or equivalent:
Power Supply Model Mains Fuse (time delay) Battery Fuse (Quick Blow)
M440 T250mA 250V
M540 T250mA 250V

Environment
All equipment except the entrance panel must be placed in a protected indoor
environment.
Lead-Acid Battery (when supplied)
The Lead-Acid Battery for the Standby Power Supply is shipped in separate packaging.
Care must be taken to ensure that the terminals of the battery are not shorted together
by metal objects as this may constitute a Fire Hazard. The Control Cabinet is IP55
rated (to exclude dust) and is vented to avoid the build-up of gases. Do not block any
vents which may be apparent.
Video Telephone
The display module of the video telephone has a high voltage circuit (2KV) which
represents a shock hazard. When the top cover of the telephone is removed,
precautions must be taken to avoid contact with this module.
