It is recommended that the re system is tested weekly or whenever
a signicant change has been made to the installation or the building
under construction. WES+ is equipped with a silent test function that
allows you to test the radio link between units without activating an
audible re alarm. You can therefore ensure each unit in the system
has a robust radio link with sufcient capacity to allow for
environmental uctuations without disturbing the site.
Initiating a silent test
Press and hold the B button on any error free unit for more than 1
second to initiate a silent test. The amber LED will illuminate for up to
30 seconds to indicate that the unit has begun a test. The Silent Test
message is propagated by radio around the system.
The test result is indicated as follows:
Pass Green LED solid illumination
Radio OK, other fault
detected
Red LED ashes followed by Amber LED
group ashes to indicate fault (see ‘Amber
LED Indication’).
No Radio Signal Amber LED group ashes to indicate fault
(see ‘Amber LED indication’).
Inspection of other system units
After a silent test has been initiated, all other units should be inspected.
The test result can be determined by examining the LEDs on each unit:
Pass Green LED solid illumination
Radio OK, other fault
detected
Red LED ashes followed by Amber LED
group ashes to indicate fault (see above).
No Radio Signal Alive Indication or Red LED ashes
followed by Amber LED group ashes to
indicate fault (see above).
Cancelling a silent test
The silent test can be cancelled from any unit, except those which are
indicating the Alive Indication, by pressing and holding the B button for
more than 1 second.
The silent test will automatically cancel 20 minutes after activation.
The unit will detect that it has been removed from its installed position
and then reinstalled. Check that after reinstallation the unit is not
displaying any fault warnings on its amber LED.
After moving a unit, we recommend that you conduct a silent test
to check that the movement has not adversely affected radio
communication.
Before shipping a unit or moving it to another site it must rst be
deactivated, in order to:
• prevent accidental triggering
• preserve battery unit life
• clear site information which would prevent it forming or joining
another site
First, remove the unit to be deactivated from the wall/ceiling and
ensure the back tamper button is not pressed.
Hold down ‘A’ and then press ‘B’ three times in quick succession. All
three LEDs will briey illuminate and then extinguish and remain off.
Note: units cannot be deactivated during a re alarm.
