NTRODUCTION
1.1 Product description
The FASD700 range of aspirated smoke detectors includes:
FASD710 and FASD712 panels (conventional or analogue addressable detectors).
FASD715 and FASD717 panels (laser detectors).
All panels are IP50 rated. An optional IP65 rating is available to allow use in many harsh
environments and where regular hosing is performed.
1.1.1 FASD710 and FASD712 panels
FASD710 and FASD712 panels have the following features:
Installation of up to two conventional or analogue addressable detectors (not
supplied) providing the ability for failsafe redundancy or mixed detection strategies.
High performance aspirator and flow monitoring circuit. The flow level is displayed on
a 10 element bar graph with adjustments for high and low flow thresholds. Flow
failure is reported to the central panel as a device fault on the primary detector.
In-line air filter to remove dust particles from the air sample. This is housed in a
removable transparent cartridge enabling rapid inspection and maintenance.
Closed loop sampling (the exhausted air can be completely returned to the sampled
area) making in ideal for use in small spaces.
1.1.2 FASD715 and FASD717 panels
FASD715 and FASD717 panels have the following features:
Two laser detectors (supplied) in single or two-channel configurations. This gives a
large monitored area using sampling holes in the place of point detectors. The
FASD717 has two pipes and can cover twice the area of the FASD715.
High performance aspirator and flow monitoring circuit to ensure a constant,
monitored flow level which can be displayed on a 10 element bar graph with
adjustments for high and low flow thresholds. Three alarm levels give warnings at
their pre-set levels.
In-line air filters to remove dust particles from the air samples. These are housed in
removable transparent cartridges enabling rapid inspection and maintenance.
RS232 Modbus port to download all the data that is logged within the unit. This can
then be used to look at events or trends over a period of time.
In addition to the above FASD715 panels also have the following features
Closed loop sampling whereby the exhausted air can be completely returned to the
sampled area.
Can be configured to require both detectors to go into alarm to avoid false discharges
of suppression systems. By using two independent detectors this removes the need
for two separate systems.
