ELECTRICAL CONSIDERATIONS

The intelligent reﬂ ective beam detector is loop-

powered and requires no external power supply.

Each beam detector draws approximately 5mA

in quiescent and 9mA in alarm from the ana-

logue addressable loop and, unless proven by

calculation*, it is recommended that no more

than ten beam detectors be powered from each

loop.

*A loop voltage drop calculation program,

known as 'Loop Calculator', has been devel-

oped by Apollo for use by system designers

and is available as a free download from the

Apollo website (www.apollo-ﬁ re.co.uk)

LED FAULT INDICATION

A fault is indicated by the amber LED ﬂ ashing

once a second.

If the drift compensation function has reached

its limit the amber LED ﬂ ashes once every 2

seconds. The detector will continue to function

but maintenance procedures should be carried

out at the earliest opportunity.
