5.8 BATTERY MANAGEMENT
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 the Smoke Screen can provide an effective
activation for at least 1 hour after a mains power failure (further detail is on the relevant Smoke Screen datasheet).
The Smoke Screen is capable of activating 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 and replacement batteries may be obtained from your Smoke Screen
distributor 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 on the PCB to permit the batteries to be disconnected from the system whilst
remaining in place (see the picture above). The delivery setting is “Off”; select to “On” if intending to use the
battery facility
.
Removal and replacement
Disconnect the mains power supply. Take off the Smoke Screen front cover, the battery compartment cover on
the left side and the mains power cover on the PCB. Disconnect the battery plugs from the PCB. Slide out the
old batteries, replace with new units and refit the plugs and covers
THE SMOKE SCREEN WILL NOT FUNCTION AT ALL DURING A MAINS POWER FAILURE IF THE BATTERIES
ARE DISABLED.
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.
