114 H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015Start-Up and Fault Management Start-UpAudible Alarm Device Control Cables (S81-F5003 Modules)1. Make sure that both conductors (+L/+L) are insulated from the earth.2. Make sure that the resistance between the positive and negative of the line is of approximately5600 Ohms.Solenoid Control Cables (S81-F5001, S81-F5004 Modules)1. Make sure that both conductors (+L/-L) are insulated from the earth.2. Make sure that the resistance between terminals +Lout and +Lin exceeds 40 Ohms.25 VDC Power Cables1. Make sure that both conductors (+L/-L) are insulated from earth ground.4.1.4 Start1. Make sure that the disconnect switch supplying 25 VDC voltage to the system and fielddevices is disabled.2. Activate the disconnect switch S1 that connects the batteries to the power supply set.3. Activate the main switch powering the power supply set.4. Use a voltmeter to measure the Vload voltage from the power supply set and check that it is25VDC.5. Use a voltmeter to measure the Vbat voltage from the power supply set and check that it is27VDC approximately.6. Activate the disconnect switch supplying field devices and the system and wait forinitialization cycle conclusion.7. During this stage, possible faults, if any, will be shown on the central unit display.8. Cut power supply set power. Make sure that central unit display shows the message: “Primaryvoltage fault”.9. Use a voltmeter to measure the Vload voltage on bus bars and check that it is 25VDC.10. Supply voltage to the power supply set. Fault condition must reset.11. Disconnect battery positive. Make sure that the central unit display shows the message:“Secondary voltage fault” within 30 seconds.12. Connect battery positive again. Fault condition must reset.4.1.5 Functional TestsFunctional tests aim to check all system features and its compliance with customer requirements.Utmost care must be taken in checking the logics of the extinguishing zones to make sure that thesystem carries out the required operations in case of fire alarm.The functional test of a safety system is deemed to be 100% valid if the following points are com-plied with:1. All inputs are tested in all of their possible operating statuses.2. All outputs are tested in all of the statuses defined by the application program.3. All program logical paths are tested.4. All preset delays are checked.5. All combinations of digital signal permutations are checked - fault conditions included.NOTE: Before carrying out any functional test, disconnect all the solenoids controlling theextinguishing systems. If necessary, replace the solenoids with a 25 VDC, 2Watt bulb to check theproper implementation of the logics.
