INSTALLATION AND MAINTENANCE INSTRUCTIONS
A300 SERIES ASPIRATED SMOKE DETECTOR
should be monitored using a separate monitor module to
return the fault.
A300E Series smoke detectors are powered by an external
24Vdc power supply.
With the use of an exhaust pipe, the system is IP65 rated,
allowing its use in many harsh environments, and
applications where regular hosing is performed.
CAUTION!
The A300 Series has been independently tested and
certified to CEA4022 and must be installed in strict
compliance with these instructions if the certification
is to be maintained.

INTRODUCTION
There are many instances where aspirated smoke
detectors are specified, but where the very high sensitivity
that is normally inherent in these devices is an
unnecessary expense. The A300E Series Aspirated Smoke
Detector provides the perfect solution.
A300E Series aspirating smoke detectors are available in
single or dual channel formats giving a large monitored area
using sampling holes in the place of point detectors.
The A310E single channel unit has a single detection pipe,
and may be used with one smoke sensor, or two sensors
which can be configured for alarm coincidence at the panel
to simulate a ‘Double Knock’ type operation. (Note: Not
included in VdS approval).
The A320E unit is equipped with two detection pipe
channels and should be fitted with one sensor for each
channel and can thus cover a greater area than the A310E.
A high performance aspirator and flow monitoring circuit
ensure a constant, monitored flow level which can be
displayed on a 10 element bar graph with adjustments for
high and low flow thresholds.
The A300E Series units incorporate in-line air filters to
remove dust particles from the air samples.
A300E Series Aspirating smoke detectors provide closed
loop sampling whereby the exhausted air can be
completely returned to the sampled area making them
particularly suitable for prison cells.
A300E Series Aspirating smoke detectors use one or two
standard intelligent or conventional smoke sensors which
communicate their status directly with the control panel
(Recommended: 7251 Laser Sensor). The A300E monitors
its own systems and uses relay contacts to signal system
faults. If using an intelligent fire system, these contacts
