124 H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015
Application Notes Notes for the Development of Systems in Compliance with the EN12094-1 Standard
6.2.14 Resetting the “Activated” and “Released” Conditions
The “activated” and “released” conditions are reset by means of the manual Reset command at
access level 2 (Reset Panel).
6.2.15 Fault Condition
The system can recognize and signal the following fault conditions:
• Interruption of the automatic actuation signal from the central unit (Alarm Module Fault)
• Interruption or short circuit of all monitored input and output lines
• Internal power supply faults
• System faults
• Wrong program running and/or corrupted memory
Faults are signaled as explained below:
• Activation of local audible indication
• Activation of the “Fault” steady light indicator on control panel display
• Detailed information on the fault type and total number of faults on control panel display
• Activation of the output for Fault condition replication
6.2.16 Out of Service Condition
All inputs and outputs relating to the fire extinguishing zones can be enabled/disabled individually
or altogether at access level 2. Any disabling will not be affected by the reset command (Reset).
The “Released” condition is not activated when in “out of order” condition, unless the signal of
extinguishing agent flow is received. (PSH) The condition of “out of order” is indicated at access
level 1 on the S81-F6001 modules by cumulative visual alarm device. The details of all exclusions
are visible at access level 1 on control panel display.
6.2.17 Release Signal Delay
The system can delay the release command for a variable time of 0 to 60 seconds. This time is set
for each fire extinguishing zone in the operator cycle at access level 3 or by Pro-S81 configuration
program.
6.2.18 Signal Representing Extinguishing Agent Flow
The system features inputs for receiving the signal that represents extinguishing agent flow (PSH).
If this signal is received without the “Activated” condition, the “Released” condition activates.
Therefore, all relevant outputs will be activated.
NOTE: The reset of the “activated” and “released” conditions can be inhibited for a certain time,
adjustable from 1 to 30 minutes. This time is set for each fire extinguishing zone in the operator
cycle at access level 3 or by Pro-S81 configuration program.
NOTE: If a function and/or a transmission medium to actuators is enabled when an alarm is
active, the extinguishing agent will be discharged only after the set discharge delay time.
