H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015 121
Notes for the Development of Systems in Compliance with the EN12094-1 Standard Application Notes
The S81-F3002, S81-F4001, S81-F4002, S81-F4003, S81-F5001, and S81-F5004 modules can be
used in redundant configuration to increase system availability. The maximum number of fire
extinguishing modules in the various configurations must not exceed the values shown in the table
below:
6.2.1 Processing of signals and indicators
The H-S81-HS system receives and shows the signals relating to the different extinguishing zones.
The central unit processes the logics. The information is sent to the display unit. Both compulsory
and optional functions are carried out by the modules as described in Sections 6.2.2 and 6.2.3.
6.2.2 Compulsory Functions
The H-S81-HS system can carry out the following compulsory functions:
• Receiving and processing the Sequence Start signal from the detection module
• Monitoring of one monitored input line for manually operated equipment
• Monitoring and control of output lines for solenoid control
• Monitoring and control of output lines for visual/audible alarm devices
• Unequivocal visual indication of the various statuses
• Control of a fault open collector output
• Control of an open collector output and visual indication of the released status
6.2.3 Optional Functions
• The H-S81-HS system can carry out the following optional functions:
• Control of release delay
• Signal representing extinguishing agent flow
• Emergency hold
• Activation of a secondary flooding sequence
• Manual only mode (Aut-Off)
• Actuation commands to equipment inside the system
• Release signals to reserve cylinders
• Actuation commands to equipment outside the system
• Emergency shutdown
• Activation of alarm devices with different signals
