●
Do
ensure other wireless devices (like RFID readers) operating
at 868MHz are at least 5m away from any RF devices
[An RFID is an alternative to optical bar code technology that uses
radio waves to capture data from product tags. These tags may be
in concealed locations and transmit data wirelessly via antenna to
an RFID reader]
●
Do
place test devices in a site survey as close as possible to
the final device positions. A site survey kit is available to assist
with this
●
Do
Consider doors as shut in any design and have them shut
during a site survey link measurement
●
Do
check critical links for directional dependency by rotating
devices during a survey. Directional information can be entered
into the device information option in the Agile IQ™ tool
●
Do
ensure when using multiple gateways in an area, that the
main communication channels for the different networks are
not on adjacent channel numbers. It is recommended that they
are separated by at least one channel to avoid any possible
crosstalk. The quality of any separating channels is not
important in this respect
●
Do
always use 4 batteries in devices
●
Do
set the device address before inserting the batteries
●
Do
check an installed, operating system for
Fire
and
Fault
events before leaving the site. A fire can be simulated with a
test magnet on an Agile™ detector (see device installation
instructions for details) and a fault can be created in a system
by removing a device from its base (
Tamper Fault
)
Don’ts
●
Don’t
locate RF devices behind obstructions that can weaken
RF signal and cause poor link quality
●
Don’t
locate Agile™ RF devices back to back where there is
little or no attenuation, as 1m separation is required between
RF devices
●
Don’t
install gateways or Agile™ RF devices near electrical
switch gear
●
Don’t
choose the main and the backup RF channels next to
one another in the frequency spectrum to have the best chance
of avoiding possible channel blocking
●
Don’t
use any RF channels that are categorised as
UNSUITABLE
in the RF energy scan table
●
Don’t
use RF channels that are categorised as
Marginal
unless this is unavoidable, and then preferably only use them
for the back-up channel
●
Don’t
accept any RF links that are categorised as
UNSUITABLE
in a Link Quality measurement
●
Don’t
leave the batteries in a detector that is not part of a mesh,
or being used in a site survey
And finally…
●
Don’t
leave an installed site without first testing the working
system for
Fire
and
Fault
events. On the Agile™ 200 Series
RF Fire System, a fire can be simulated with a test magnet
on an Agile™ detector (see device installation instructions for
details) and a fault can be created in a system by removing a
device from its base (to generate a tamper fault)
