Push Button
Keys
These buttons enable various systems functions but can not be used to
configure the system. The Buttons can be disabled by the Systems
Administrator.
Mode/Test (Dual Function): Selects toggles between the sensitivity, smoke
level and zone number modes. When depressed for more than two seconds it
performs a light test function.
Silence: This button silences any alarm or fault warnings. It also stops the
LEDs from flashing to acknowledge a fault or alarm condition.
Reset: Resets any latched alarms and faults on the detector. Any active
alarms or faults are reported again after the time delays have elapsed.
Isolate: Isolates the detector from any external devices or systems (an isolate
alarm will normally be raised at the Fire Alarm Control Panel (FACP)).
Note:
It is normal practise to signal the Isolate condition to the Fire Control
Panel using the Isolate relay
Numerical
Display
Sensitivity: Shows the level of smoke that must be measured to illuminate the
entire bar graph and always corresponds with the fire alarm level.
Smoke Level: Indicates the current level of smoke in the relevant VESDA
address and is represented as % obs/m or % obs/ft.
Zone Number: This is the VESDA Zone number assigned to the Display
Module.
Note:
The Mode Button is used to select the parameters represented by the
Numeric Display (sensitivity, smoke level, zone number). The values dis-
played in the numerical display represent the current readings for that mode.
