An optional Self Contained Power Supply unit can be installed directly below the Detector. This unit will
provide a supervised supply with the addition of battery back-up in case of mains failure. The Self
Contained Power Supply cannot be used when the Detector is either mounted upside down or when flush
mounted into the wall.
Electrical connections to the Detector are possible by using the provided pre-formed conduit knock-outs.
The conduit knock-outs are located top, bottom or rear of the Detector back box. The Self Contained
Power Supply also provides similar conduit knock-outs for use when it is mounted below.

CAUTION
ANTI-STATIC PRECAUTIONS
WHEN HANDLING ANY ELECTRIC COMPONENTS OR
CIRCUIT BOARDS ANTI-STATIC PRECAUTIONS MUST
BE CARRIED OUT. FAILURE TO DO SO MAY RESULT IN
COMPONENT DAMAGE.
Static discharge can be reduced by adhering to the following guide lines.
(1) Always use conductive or anti-static containers for transportation and storage, if returning
any item.
(2) Wear an earthed wrist strap while handling devices and ensure a good earth is
maintained throughout.
(3) Never subject a static sensitive device to sliding movement over an unearthed surface
and avoid any direct contact with the pins or connections.
(4) Avoid placing sensitive devices onto plastic or vinyl surfaces.
(5) Minimise the handling of sensitive devices and Printed Circuit Boards (PCBs).
