8 Warning MESSAGE 1 ALARM LEVEL 1 ALARM LEVEL 2 INCIDENTS • Interior temperature >50 °C Possible causes: • Temperature build-up due to battery charging processes • Ventilation system failure • Smoke detector detects incipient smoke development Possible reasons: • Smoke detection without simultaneous temperature rise • Alarm level 1 has been triggered • Interior temperature >70 °C Possible reasons: • Fire development SYSTEM REACTIONS CORE • Acoustic signalling with medium tone interval • The potential-free switching contact forwards an alarm PRO • The warning light (red LED) is activated and lights up permanently, the function indicator (green LED) goes out. • Alarm triggers with slow sound interval • The socket strips switch off • The potential-free alarm contact forwards an alarm • The warning light (red LED) is activated and lights up permanently, the function indicator (green LED) goes out. • Alarm triggers with medium sound interval • The potential-free alarm contact forwards an alarm In the PRO CHARGE model • Switching off the technical ventilation and power strips • The warning light (red LED) switches from steady light to flashing light • The alarm switches to a fast sound interval • The fire suppression system trips In the PRO CHARGE model • Switching off the technical ventilation and power strips ULTRA • Function indicator changes from green to flashing yellow • Alarm triggers with slow sound interval • The fan increases its speed for a short time • The socket strips switch off • The potential-free alarm contact forwards an alarm • The function indicator flashes red • Alarm triggers with rapid sound interval • The ventilation flaps close • The fan and the socket strips switch off. • The potential-free alarm contact forwards an alarm • The function indicator flashes red • Alarm triggers with rapid sound interval • The ventilation flaps close • The fan and the socket strips switch off • The potential-free alarm contact forwards an alarm • The optional fire suppression system trips SUBSEQUENT MEASURES • Immediate inspection caused by qualified inhouse personnel • At an internal temperature below 50 °C, return to normal operation, the visual and acoustic signalling is switched off Immediate inspection caused by qualified personnel (e.g. fire brigade) to initiate further measures if necessary If the smoke detector does not detect any further smoke inside the cabinet, the system can be reset to normal operation caused by briefly disconnecting it from the mains voltage The overall system can then only be assessed by an authorised asecos service technician and reset to normal operation if possible. At least the fire suppression unit and smoke detector must be exchanged before doing so. ION-LINE OUR asecos ION-LINE SAFETY CONCEPT ION-LINE safety storage cabinets offer you the safety you need for storing and charging lithium-ion batteries. The CORE, PRO and ULTRA models immediately detect any fires that occur in the cabinet. This allows employees to evacuate the building quickly if an alarm sounds. Resulting from the connection to a permanently manned building control system, rescue services can: • to receive an alarm and be on site quickly. • to immediately take further measures, for instance evacuating the building, to minimise subsequent damage caused by smoke or extinguishing water. ION-LINE cabinets are equipped with a transport base and quick-release power supply for safe evacuation. When the cabinet is removed from the setup location, this plug connection disconnects independently.
