6.1 OPERATION
While the Smoke Screen is heating up the LCD display will show a “Live Status” in code format and the LED
indicator will be yellow. If the cover is open “Tamper Fault (Ti)” will be displayed on the LCD and the LED indicator
will flash yellow once every 5 seconds; a tamper indication will not, on its own, prevent the Smoke Screen from
producing smoke. When the Smoke Screen reaches the correct working temperature, and a full smoke fluid
consumable has been correctly installed, the LED Indicator will go Green and the LCD Display will show the
current status on the machine (see ‘Codes for live status’).
Stopping smoke
If the ‘Hold-off’ is closed during an activation the Smoke Screen will continue to produce smoke for the set
Smoke Time. Once initiated an activation can be stopped only by closing the ‘Alarm Set’.
Re-triggering smoke (hold-off attached)
If, after it has made smoke for the pre-set time, the Smoke Screen receives another hold-off alarm with open
‘Alarm Set’ and ‘Trigger’ inputs it will ‘re-trigger’ and make smoke again.
6.2 TESTING
Full alarm test
Where possible a full alarm test should be conducted to check all inputs, outputs and wiring
connections to the Smoke Screen are correct. The Smoke Screen will fire for the designated ‘Smoke Time’ once
the ‘Alarm Set’, ‘Trigger’ and ‘Hold-off’ (if fitted) contacts are open. It will re-trigger if the ‘Alarm Set’ remains open
and either the ‘Trigger’ and/or the ‘Hold-off’ inputs are cycled after the set ‘Smoke Time’. It will stop producing
smoke if the ‘Alarm Set’ contacts are closed.
Panic test
Where possible a full Panic test should be conducted to check the wiring connections to the Smoke Screen are
correct. The Smoke Screen will fire for the designated ‘Panic Time’ once the Panic input changes state.
NB: A Panic activation can be stopped before the end of the programmed smoke time only if the ‘Set’ is cycled
to alarm and back to restore.
Smoke Screen standalone test
The Smoke Screen can be tested when it is ready to operate (indicated by a steady green LED) and it is not in
“Service Mode” by pressing the buttons on the PCB marked “PB1” or “PB2” (see the section “Circuit Board Layout”
for the location and function description for these buttons).
NB: this does not check that the inputs and connections to the Smoke Screen are correct.
