WES
3
Installation and Operations Manual V2.0 Ramtech Electronics Limited 2020
During the System Test mode, the WES
3
network isolates all devices
in the network, allowing a full physical test of each unit, without
activating the site-wide alarm. Call Points can be triggered manually,
and Detectors can be triggered using standard test equipment such as
smoke spray or a heat probe.
Cancelling a System Test
Once the System Test is complete, return to the CONNECT unit and
press either the
R
or
Q
button to complete the test. It is important
to be aware that, whilst in System Test mode, the WES
3
network
is inactive and a site wide alarm cannot be triggered from any unit.
System Test mode must be exited from the CONNECT unit in order to
reactivate the network.
Note : Following initial installation, wait for a minimum of 60 minutes
before starting the first system test. During this time, the WES
3
units
will self-calibrate to adjust for background radio noise which may
impact the accuracy of the system test.
The test result is indicated as follows:
Pass
Green LED solid illumination
Radio OK, other fault
detected
Red LED flashes followed by Amber LED
group flashes to indicate fault (see ‘Amber
LED Indication’).
No Radio Signal
Amber LED group flashes to indicate fault
(see ‘Amber LED indication’).
System Integrity Test (Polling)
WES
3
includes a System Integrity Test that can report on changes to
the network configuration, such as when additional or unexpected units
are detected on the network, or when units have been removed.
The Integrity Test is conducted automatically twice daily and can also
be activated on-demand from the WES
3
CONNECT unit. To activate
the Integrity Test, go to the Test Menu and slect System Poll to initiate
the integrity test.
While the Integrity Test is being performed, a message will be displayed
on the screen:
Any additional units that have been found on the network since the last
system poll will be displayed as a ‘NEW’ notification on the CONNECT
unit. Any units that have been removed from the network since the last
system poll will be displayed as a ‘GON’ notification.
In addition to the automatic system integrity test and the on-demand
polling feature, WES
3
provides immediate real-time notification when a
unit is removed from the network, displayed on the CONNECT unit as
a ‘REM’ notification. Note that system polling is limited to the first 128
WES
3
units added to the network. Beyond this number, further units
can be added but will be excluded from the integrity test.
After moving a unit, we recommend that you conduct a system test
to check that the movement has not adversely affected radio
communication. Ensure any site fire plans are updated with any
revisions to WES
3
unit numbering and location.
Before shipping a unit or moving it to another site it must first 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 in.
Hold down ‘A’ and then press ‘B’ three times in quick succession. All
three LEDs will briefly illuminate and then switch off.
Note: units cannot be deactivated while a fire alarm is active.
