ENERGY SAVING MODE (ESM)
When ESM is set
and the Alarm Panel input to the Smoke Screen is “Unset” the Smoke Screen
lowers its running temperature to a standby level to reduce power consumption and cost. When
the Smoke Screen
receives an ‘Alarm Set’ input it automatically heats to its normal operating
temperature.
SERVICE MODE
Setting dip switch No 3 of the bank
marked “On – Service Mode” (see diagram under “Circuit
Board Layout”) to “on” puts the Smoke Screen into “Service Mode”. This setting prevents the
Smoke Screen from making smoke whilst work is conducted with power applied.
FAILURE TO DISABLE SERVICE MODE WHEN NO LONGER REQUIRED WILL PREVENT
THE SMOKE SCREEN OPERATING.
TURBO SMOKE MODE
When
“Turbo Smoke Mode” is set (see section under “Programming”) the Smoke Screen produces
a high-volume burst of smoke to provide rapid obscuration of a local, high value protected area. In
“Normal Smoke Mode” the Smoke Screen produces a short full-output burst followed by a lower
output over a longer period.
TAMPER
There are 4 tamper circuits on the Smoke Screen, one on each cover (front, battery and fluid) and
an external tamper input on PCB Terminal Block “B”. The external tamper input can be disabled if
not in use by selecting Dip Switch 3 (marked “TAMP”) to “On”, which bridges the input pins on the
PCB. A “Tamper Status” output is provided on PCB Terminal Block “C”. A tamper ‘open’ state
provides only an indication of the event; it
does not
automatically activate the Smoke Screen or
prevent it from activation.
FLUID MANAGEMENT
Fluid capacity.
There are 2 sizes (500ml or 1000ml) of
transparent bag containing ‘Smoke Fluid’ for
the Smoke Screen. It can also be operated with an external 5000ml bottle
– please contact Concept
Smoke Screen if you wish to use this facility.
Fluid monitoring.
The Fluid Level is monitored using an on-board timer that measures the amount of
fluid used by timing consumption when the Smoke Screen is activated. Each time the bag clamp is
unfastened and the fluid bag is replaced the micro switch is cycled which resets the timer and the
Smoke Screen will calculate this as a new fluid bag.
See the section on “Programming” to set the
volume of fluid available to the Smoke Screen.
External reservoir.
When a 5-Litre external fluid bottle is used and the timer is set to 5000ml via
the LCD control panel the function of the micro switch on the fluid bag holder is changed and a bag
should not be fitted. In this mode, with power applied to the Smoke Screen, pressing and leaving
open the micro switch on the fluid bag holder resets the fluid timer to 5000ml available.
Changing a fluid bag:
Ensure that power is applied to the Smoke Screen. Open the right-hand
access panel. Unscrew the bladder neck holder retaining screw and the bag support screw. Push
the fluid
probe into the “out” position in the bag neck. Place the other end of the bag onto the
support and insert the retaining screw.
