5.1 SCREEN SENSOR
A “Screen Sensor” can be connected to the Sentinel as shown in the “Generic Connection Diagram”. When this is
integrated the system detects a drop in the fog density in the protected area and will re-trigger the Sentinel to
maintain the fog level. When fitted the Screen Sensor is connected to the Hold-off input pins and, consequently, it
prevents the use of a hold-off detector.
NB: It is critical that the Screen Sensor is installed in an area that receives the maximum fog coverage. It will not
operate correctly if this is not achieved. (See 4.2 generic connection diagram).
5.2 ENERGY SAVING MODE (ESM)
When ESM is selected 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. If the Smoke Screen is in ESM mode and
is activated as soon as the alarm is set, i.e. before it has heated to normal operating temperature, it will still
produce smoke but possibly for a shorter period than the set smoke time.
5.3 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. To highlight that the Smoke Screen is in “Service Mode” the tamper output is put
into an alarm state.
FAILURE TO DISABLE SERVICE MODE WHEN NO LONGER REQUIRED WILL PREVENT THE SMOKE SCREEN
OPERATING.
5.4 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.
