• Functional state of power supply units and accumulators (APS) of the control panel and of the system power supply modules.
• State of the batteries of the self-powered devices (sirens, communicators).
• Functional tests of the sensors that make up the system.
• Checks about the state of cleanliness of the analysis chambers of the optical sensors.
• Effi ciency of the control organs of the control panel and repeaters.
• Functional and operational effi ciency of the acknowledgement, evacuation and system recovery procedures.
• Effi ciency of manual alarm button module.
• Effi ciency of optical and acoustic notifi cation module.
• Effi ciency of phone communicators (phone call tests).
• Verifi cation of system actuations entrusted to input and output interface modules, etc.
