Operation
The Smoke Screen is fitted with a battery to provide power to the electronic circuits and pump (not to the fluid heater)
in the event of a mains power failure. This ensures that 20 minutes after a mains power failure at an ambient
temperature of 20°C the Smoke Screen can provide a minimum 40 second activation. The Smoke Screen is capable
of activating solely on mains power in the event of a battery fault or if the batteries are not fitted; in the latter case, to
avoid battery fault indications, the facility should be disabled (see “Programming”). The Smoke Screen is supplied
with a set of batteries but they are not fitted on delivery. Replacement batteries may be obtained from your Smoke
Screen installer or Concept Smoke Screen.
Battery protection
To prevent damage to the batteries caused by running them to a completely discharged state, the Smoke Screen will
switch off the battery power 1.5 hours after a mains power failure, at which time the unit is too cold to activate; the
Smoke Screen will start up normally as soon as mains power is re-applied.
Battery switch
The Smoke Screen has a switch above the battery compartment to let the batteries be disconnected from the system
whilst remaining in place. The delivery setting is “Off”; select to “On” if intending to use the battery facility.
Be aware of high voltage
in the Smoke Screen. The
electrical supply should be
switched off before
changing the batteries.
If the generator has been
in service the heater block
and connected parts will
be extremely hot and will
cause injury if touched.
Switch off and allow the
heater block to cool.
