Time schedule must be determined with the system operator for the following test sequences: Alarm tests (incl. remote transmission) – Performance check of fire control installations – Any follow-up training – Any clarification – Siemens Building Technologies 007833_a_en_--.doc Fire & Security Products 03.2004...
Replace all detectors in "Drift" conditions. Change of use Inspect all reported changes to the building, especially rooms with new utilization. Make all necessary modifications to the FC700A system with regards to this change. Planned modifications Check whether all modifications have been carried-out, e.g. changes to diagrams,...
Check the lithium auxiliary batteries by disconnecting the power supply for approx. 15 minutes. After switching-on again, check the date, time and fault message. If there is any loss of date, replace the corresponding unit. Siemens Building Technologies 007833_a_en_--.doc Fire & Security Products 03.2004...
Control unit check Control unit check Hardware Assess the condition of the housing, visual check on hardware modules and batter- ies. Check mounting screws, terminals and plug-in connections. Siemens Building Technologies 007833_a_en_--.doc Fire & Security Products 03.2004...
5. Activate 1 ALARM, acknowledge and reset. 6. Activate 1 FAULT, acknowledge and reset. 7. Log-out. Cleaning Clean display window and front panel with mild soap. Do not use abrasive sol- vents. Siemens Building Technologies 007833_a_en_--.doc Fire & Security Products 03.2004...
Check for each line whether a short circuit / open line acti- vates a FAULT signal. Check the loop line function. During the short circuit also check the isolator function. Overhaul at the factory of all automatic fire detectors. See chapter 9.2 Siemens Building Technologies 007833_a_en_--.doc Fire & Security Products 03.2004...
